Treatment and Prevention of Sports Injuries

Essentials

  • Recovery is based on quick and effective first aid. This article describes new international treatment protocols for the acute and post-acute phases.
  • Sports injuries can be prevented, and doctors may play a significant role there.

Epidemiology of sports injuries

  • Sports injuries are the biggest class of accidents causing injuries.
    • In 2017, the Finnish population (5.5 million people) experienced 420 000 cases of sports injuries. Medical attention was needed in 121 000 cases.
  • More than one in four sports injuries involves the knee or ankle. Back injuries are also common in both men and women.
  • The most common chronic complaint is osteoarthritis subsequent to a joint injury.
    • An injury to the anterior cruciate ligament of the knee increases the future risk of osteoarthritis many times compared with a healthy knee.
  • Exercise obtained through daily activities and recreational sports is safe: the average individual risk is 0.7 injuries / 1 000 hours of exercise.
  • Fitness training and competitive sports carry an average a risk of 3.1 injuries /1 000 hours of exercise.
    • The risk of injury shows significant variation depending on the type of fitness training or competitive sport.
  • The average risk of sustaining an injury during exercise is slightly higher in men than in women, but the incidence of severe knee injuries is higher in women than in men.
  • Individuals from 15 to 34 years have the highest risk of sports injuries. With age, the risk of injury decreases. However, the risk of exercise-related cardiac events increases with advancing age.
  • Competitive and contact sports are associated with a significantly increased risk of injury compared with ordinary exercise.

Injury risk and typical injuries for different exercise types

  • Injuries typical for different exercise types are presented in table T1.
  • The safest exercise types for a beginner are walking, Nordic walking, swimming, gym workout, aerobics, ice skating, cross country skiing, rowing, dancing, golf and bicycling.
  • The majority of sports injuries are soft tissue strains, tears, bruising or soreness.
    • Injuries are often the result of sudden trauma.
    • Overuse injuries are also very common; they account for 35% of all injuries in women and for 22% of those in men.

Knee and ankle injury mechanisms

  • Ligament injuries to the knee are, in the majority of cases, the result of sudden stopping or a sudden change in direction.
    • At the moment of injury the person's weight is usually borne by one leg with the knee bent and turned inwards (dynamic valgus). This may cause the knee to give way, exerting a sudden pulling and shearing force to the knee ligaments.
  • Factors impairing the control of knee position include knock knees, poor proprioception, inadequate muscle strength, faulty technique as well as deficits in lower limb muscle balance, coordination and mobility.
  • The most typical sprain injury affecting the ankle is an inversion injury: the foot rolls underneath the ankle or leg.
  • The risk of an ankle injury is increased by ligamentous laxity (loose ligaments), previous sprains as well as deficits in both running technique and control of ankle position.
    • Essential for the control of ankle position are the following: good proprioception, strength of the muscles that affect the foot position and their correctly timed activation, as well as correct running and jumping technique.
  • The positions of the knee and ankle are also influenced by the position and control of other parts of the body, e.g. the upper and lower torso and the hips.

Recovery from soft tissue injury

  • The stages of healing in soft tissue injuries, including ligament, tendon and muscle injuries are:
    • haemostasis stage (hours from injury): blood vessels at the site of injury constrict and blood coagulation system is activated.
    • inflammatory stage (0-7 days from injury): circulation and vascular permeability increase at the site of injury and inflammatory cells are directed towards the site of injury; there is pain, swelling, redness and warmth around the injured soft tissue
    • repair and regeneration stage i.e. proliferation stage (1-3 weeks from injury): new weak scar tissue starts to form at the site of injury
    • maturation and remodelling stage (> 3 weeks from injury) the proteoglycan and water content of the tissue starts to decrease and stronger type I collagen starts to replace the weaker tissue in which type III collagen is overrepresented.
  • Injured ligaments and tendons begin to be able to withstand normal workloads about 6-8 weeks after the injury.
    • However,total maturation of soft tissues will take 6-12 months. For example, the anterior cruciate ligament remains very weak 2-3 months after surgical repair, and gentle running should usually not commence until about 3 months post surgery.

Treatment process

  • The RICE treatment principle, i.e. Rest, Ice, Compression and Elevation has been long utilized. According to a newer recommendation, the immediate treatment of an acute injury (PEACE) is most effective when combined with the subacute healing process of tissues (LOVE).
  • There is no convincing evidence on the previously recommended cold therapy, although it may reduce pain in the initial phase. In cold therapy, an ice pack or cold pack is placed over the injury for 15-20 minutes at a time and this is repeated, as necessary, every 1-2 hours.
    • It is not advisable to continue cold therapy for more than a few hours, since prolonged cold therapy may slow down the healing process.
    • One should be careful not to cause a frostbite injury to the skin.
  • Average healing time of most common sports injuries: see table T2.

Acute treatment protocol - PEACE

  • P (Protect). Unload or restrict movement during the first (1-3) days after the injury to reduce bleeding and prevent further damage to the site of injury.
  • E (Elevate). Elevate the injured limb or other body part, if possible, higher than the heart to promote interstitial fluid flow away from the site of injury.
  • A (Avoid anti-inflammatory modalities). To the extent possible, avoid use of anti-inflammatory factors in the initial treatment.
    • Pharmacotherapies affecting the inflammatory process, such as NSAIDs, may hinder the healing process of tissues through preventing the beneficial effects of inflammatory reaction on tissue healing. In bone fractures, for example, use of NSAIDs slows down ossification.
    • The evidence on the efficacy of cold therapy in the treatment of acute tissue injuries is scarce and partly controversial. Prolonged cold therapy may hinder the progress of inflammatory reaction and hence slow down the repair process.
  • C (Compress). Mechanical compression around the injured tissue reduces swelling and interstitial bleeding.
  • E (Educate). Encourage the patient to an active and self-directed rehabilitation. Passive treatment modalities are rarely beneficial in the treatment of an acute injury. Avoid over-treatment and encourage the patient to get a grip on the treatment process themselves. Provide the patient with realistic expectations concerning the recovery time.

Treatment protocol after the acute phase - LOVE

  • L (Load). Replace rest with optimal loading.
    • The new recommendation emphasizes that loading should be started and normal activities resumed as soon as symptoms allow. Optimal loading without exacerbating pain promotes healing of tissues through movement (mechanotransduction).
    • Normal training often needs to be replaced with alternative exercises so that the developing scar would be as small and strong as possible.
  • O (Optimism). Support optimistic patient expectations towards healing while at the same time remain realistic concerning the recovery time. Catastrophization, depression and fear of movement are associated with worse outcome during recovery from injury.
  • V (Vascularisation). Support the formation of new blood vessels.
    • Aerobic exercise started a few days after injury increases blood flow in injured tissues, promoting neovascularization and hence healing of tissues. Aerobic exercise and early mobilization improve physical function and reduce the need for pain medication.
  • E (Exercise). Do physical exercises that prevent new injuries. Start therapeutic training early, restoring mobility, strength and proprioception.
    • Pain should be avoided and the description of pain sensation should be used as a guide for exercise progressions.
    • Therapeutic exercise that supports the neuromuscular system prevents the occurrence of new injuries.
    • Neglecting active rehabilitation leads to poor orientation of scarring and new tissue and to poor strain tolerance, increasing the risk of the injury recurring.

Injury prevention Stretching Before or after Exercise to Prevent Muscle Soreness, Cold-Water Immersion for Muscle Soreness after Exercise, Prevention and Treatment of Lower Limb Stress Fractures in Young Adults

  • Prevention of sports injuries
    • Using surface-specific shoes with good shock-absorbing ability and changing shoes to vary the load on the lower limbs and the back
    • Semi-rigid ankle supports prevent ankle injuries effectively in athletes with increased susceptibility to ankle sprain due to a history of ankle injury or loose ligaments.
    • Warm-up should include regular and year-round exercises targeting muscles, tendons and joints to improve position control, technical skills and reaction time. The primary aim of exercise programmes should be control of movement and development of a technical performance specific to the type of sports and thus reduction of faulty loading predisposing the athlete to acute and overuse injuries. For example, landing without flexing the knees will predispose the athlete to jumper's knee and anterior cruciate ligament injuries of the knee.
    • Training specific to the type of sports performed slowly, using heavy weights, which increases the cross-sectional tendon area and the overuse tolerance of tendons, has proved effective in preventing tendon stress injuries, such as jumper's knee or Achilles tendon problems.
    • Structured and supervised treatment and rehabilitation of previous injuries
    • The use of high quality equipment and protective clothing
  • Too early a return to intensive sporting activity should be prevented at all costs: 30% of all sports injuries are recurrences of previous injuries.
  • New exercises should be introduced carefully and gradually to allow tissues time to adjust to the new type of training loads.
  • Overuse injuries in growing children can best be prevented by not concentrating on a single sport during the pubertal growth spurt; training should consist of multiple sports. The training of a growing child should not include powerful and abrupt tearing movements or maximal weights.
  • Addressing attitudes can also be beneficial: an improperly aggressive style of play in team sports should already be addressed at youth training level; this will contribute towards a reduced risk of injuries in adulthood.
  • The safety of exercising can also be improved with government driven initiatives, such as the creation of bicycle and pedestrian traffic lanes, and the promotion of the use of protective gear.
  • Using a helmet when cycling, roller skating, ice skating, downhill skiing or snowboarding reduces the risk of a severe head injury. It should be noted that a helmet will not prevent very mild brain injuries (concussion) and may give a false feeling of safety for young athletes.
    • Padded shield protectors that deflect and absorb impact are effective in injury prevention.
    • A hip protector shield increases an elderly person's safety during exercise.
  • Find out about local materials supporting athletes' health.

Head injuries in athletes

  • Cerebral concussion Minimal and Mild Traumatic Brain Injury represents a functional rather than structural disturbance of brain function caused directly or indirectly by an external force.
  • The very suspicion of cerebral concussion requires stopping the sports activity immediately, and the athlete should not participate in any sporting activity within the next 24 hours.
  • Cerebral concussion is a clinical diagnosis. The head injury should be assessed multidimensionally using a SCAT5 concussion assessment tool http://bjsm.bmj.com/content/51/11/851.
  • Recovery from concussion usually takes 7-10 days. More extensive examinations are needed in association with more severe injuries, if symptoms persist or the diagnosis is unclear.
  • Urgent imaging is indicated by less than 15 points in Glasgow Coma Scale An Unconscious Patient, by the presence of unconsciousness and by anterograde or posterograde memory gap.
  • The patient should resume sports gradually, increasing the load little by little and avoiding symptoms. Competition can only be resumed when the person in full-scale training remains cognitively and physically asymptomatic.

Jumper's knee (patellar insertion tendinitis)

  • Patellar tendinitis causes enthesitis type pain on the posterior surface of the proximal insertion site for the patellar tendon at the inferior patellar pole.
  • The condition is often a result of repetitive overload due to jumping, which has caused inflammation at the insertion site and tearing of some of the tendon fibres.
  • As the condition becomes chronic, the insertion site usually shows degeneration.
  • Similar sport-induced conditions also occur at the superior patellar pole (the distal insertion site for the quadriceps tendon) and at the anterior tuberosity of the tibia (the distal insertion site for the patellar tendon).

Symptoms and signs

  • At first, pain is only present after exercise, particularly if the knee is bent for a long period. Later on, pain is also present during exercise, particularly when jumping, running or deep squatting. In the most advanced stage, knee pain is present at rest.
  • Palpation will reveal point tenderness at the inferior patellar pole, and occasionally also more distally at the patellar tendon. Diagnosis can in most cases be made on the basis of history and physical examination alone, and imaging studies are only indicated in unclear or persistent cases.
    • In chronic patellar tendinitis, x-rays may show a bone spur or a loose bone fragment at the inferior patellar pole. Ultrasonography and magnetic resonance imaging (MRI) often detect local tissue oedema, macroscopic tendon damage and a possible area of focal degeneration.

Treatment

  • Initially rest and anti-inflammatory analgesics. The painful area can be gently rubbed with an ice cube or NSAID gel.
  • Running and jumping on hard surfaces and squats should be avoided. The patient should be taught to allow the knees and hips bend slightly when landing from a jump.
  • Other potentially beneficial forms of treatment:
    • Eccentric anterior and posterior thigh exercises for several weeks. Training slowly, using heavy weights, increasing the cross-sectional tendon area and the stress tolerance of tendons has proved most effective. An exercise session should last 90 minutes, and exercises should be performed three times weekly for 12 weeks. Painful exercising, such as running, should be avoided during that period.
    • If symptoms persist, control of the lower torso and alignment of the lower limb should be examined and guidance provided for the necessary exercises. Control of the alignment of the lower limbs can be improved through exercises improving the neuromuscular system. Exercises for hip abductor and external rotator muscles are particularly effective in correcting deficiencies in the alignment of the lower limbs.
    • Stretching exercises for the quadriceps muscle and the patellar tendon may prove to be beneficial.
  • A glucocorticoid/anaesthetic injection may be administered in persistent cases to the posterior surface of the tendon's upper insertion site (using a lateral approach to insert the needle behind the tendon). Repeated injections should be avoided as they may promote tendon degeneration. No more than a total of three injections should be administered, and an interval of 2 weeks between the injections is recommended. Injections are not recommended for growing children.
  • Physical therapy (ultrasound, laser, electrotherapy) is equivalent in efficacy to placebo treatment.
  • Occlusion of peritendinous vessels, i.e. sclerotherapy, and platelet-rich plasma are ineffective forms of treatment.
  • Chronic patellar tendinitis can be treated surgically, usually by longitudinally excising the base of the involved tendon followed by debridement of degenerated tendon tissue and possible calcification from its inferior surface.

Shin splints (medial tibial stress syndrome)

  • A painful condition with tenderness on palpation felt along about 3-8 cm of the medial edge of the tibia, often bilaterally
    • Pain characteristically occurs about 10 cm above the medial malleolus but may occur at almost anywhere along the length of the medial edge of the tibia.
  • Types of sports involving abundant, repetitive impact load predispose people to shin splints. Other risk factors include female sex, being overweight, overpronation of the foot, valgus malalignment of the knee, excessive external rotation range of the hip, impaired control of the lower torso and impaired activation of hip abductor muscles.
  • The aetiology of the pain from shin splints is unknown but three main aetiologies have been described: osteogenic pain, irritation of local tendons and periosteum (enthesitis, periostitis), and pain in the fascial compartment (increased compartmental pressure). Shin splints are probably due to a combination of these aetiologies, slightly differently emphasized in different patients.
  • Similar sport-induced conditions also occur at the anterior tibial edge (anterior shin splints), at the back (posterior shin splints) and laterally stemming from the peroneal muscles (lateral shin splints).

Symptoms and findings

  • At first, pain may only be present after exercise, later on also during exercise. In the most advanced stage, lower leg pain is present at rest.
  • The diagnosis of shin splints is based on typical pain symptoms at the medial edge of the tibia and tenderness on palpation of the painful area. Osteogenic pain is sharp and restricted to a small area. Pain originating from the fascia and tendons is located in a larger area at the medial edge of the tibia, and its intensity and location vary. Pain from the fascial compartment is a dull ache of the claudication type.
  • In the doctor's office, alignment of the patient's lower limbs and ranges of joint motion should be checked. Control of the lower torso and activation of hip abductor muscles can be indirectly assessed by one-leg squat and drop jump tests. A hand dynamometer can be used to assist in measuring strengths.
  • Imaging studies generally offer no help in diagnostics, and they are usually not indicated. In some cases, x-rays or MRI may be necessary to exclude a tibial stress fracture Stress Fractures. The MRI findings in a tibial stress fracture may include a periosteal reaction on the tibial surface and bone marrow oedema.

Treatment

  • The cornerstone of the treatment of shin splints is reducing and shifting the load. In the case of pain affecting the posterior lower leg, a heel strike gait pattern should be encouraged because this will reduce the load on plantar flexors of the ankle, shifting it more towards the knee and pelvis. In pain of the anterior lower leg, a forefoot strike gait should be encouraged.
  • In the acute stage, the painful area can be lightly massaged with, for example, an ice cube or an anti-inflammatory analgesic gel (so-called shin splints massage). A course of anti-inflammatory analgesics may also be necessary.
  • Complete rest is unnecessary. Alternative forms of exercise, such as exercising at a gym, cycling, swimming or aqua jogging can be recommended.
  • The patient should be taught exercises for hip abductors and external rotators, and control of alignment of the lower limbs should be improved.
  • As control of the lower torso and alignment of the lower limbs are improved, it is rarely necessary to start using support orthotics correcting the position and guiding movement. Nevertheless, orthotics can be used in thin-soled working and leisure-time shoes as shock absorbers and in cases where there is clear structural malposition in the foot or ankle area that cannot be otherwise controlled Prevention of Lower Limb Soft-Tissue Running Injuries.
  • Glucocorticoid/anaesthetic injections are not routinely used in the treatment of shin splints. Injections are not recommended for growing children.
  • Physical therapy (ultrasound, laser, electrotherapy) has no place in the treatment of shin splints.
  • Completely chronic shin splints may be managed with surgery, in which a single longitudinal incision is made along the deep leg compartment at the medial tibial edge (fasciotomy). See also Muscle compartment syndromes Muscle Compartment Syndromes.

Achilles tendinitis (peritendinitis achillei)

  • A painful condition affecting either the Achilles tendon itself (peritendinitis) or its insertion site to the calcaneus (enthesitis). The condition is often caused by repetitive stress leading to tendinitis and tearing of tendon fibres.
    • Pain around the insertion site may also be due to inflammation of the bursa between the Achilles tendon and the calcaneus, known as retrocalcaneal bursitis.
  • If the condition becomes chronic, adhesions form around the tendon, and the tendon often thickens and starts to degenerate and takes on a fusiform appearance. Often an area of focal degeneration is present within the tendon, and occasionally even tendon calcification.
  • Similar sport-induced conditions also occur, for example, in the extensor tendons of the knee (jumper's knee), in the shoulder (supraspinatus tendinitis) and the elbow (lateral epicondylitis).

Symptoms and findings

  • The condition is most common in runners. At first, pain is only present after exercise, later on also during exercise, even when only walking. In the most advanced stage, pain around the Achilles tendon is present at rest.
  • Palpation will reveal point tenderness either over the tendon itself or at its insertion site on the calcaneus. The tendon may be visibly thickened. Diagnosis can in most cases be made on the basis of history and physical examination alone, and imaging studies are only indicated in unclear or persistent cases.
    • X-rays may show a bone spur or loose calcium fragments within the tendon or its calcaneal insertion. Ultrasonography and MRI often detect peritendinous oedema, macroscopic tendon damage, an area of focal degeneration and, possibly, fluid in the retrocalcaneal bursa.

Treatment

  • The cornerstone of the treatment is load reduction and load change. Initially, the patient should rest and a heel strike gait pattern should be encouraged because this will reduce the load on the Achilles tendon and other plantar flexors of the ankle, moving it more towards the knee and pelvis.
  • In the acute stage, an anti-inflammatory analgesic as a course of 3-7 days. It is important to avoid all physical exertion/strain that causes pain.
  • Calf and Achilles tendon stretches, as well as a short-term use of a heel wedge, may be beneficial.
  • Calf muscle exercises for several weeks (e.g. calf raise and heel drop exercises)
  • A glucocorticoid/anaesthetic injection around the tendon or into the bursa may be given in the acute or subacute stage. Later on, such injections will probably no longer be useful. Repeated injections should be avoided as they may promote tendon degeneration. No more than a total of three injections should be administered, and an interval of 2 weeks between the injections is recommended. Injections are not recommended for growing children.
  • Physical therapy (ultrasound, laser, electrotherapy) has no place in the treatment of Achilles tendinitis. Occlusion of peritendinous vessels, i.e. sclerotherapy, and platelet-rich plasma are also ineffective forms of treatment.
  • If symptoms persist, control of the lower torso and alignment of the lower limb should be examined and guidance provided for the necessary exercises. Exercises for hip abductor and external rotator muscles are particularly effective in correcting deficiencies in the alignment of the lower limbs.
  • Chronic Achilles tendon problems can be treated with surgery. Several types of surgery are available including the excision of adhesions from around the tendon. Longitudinal tenotomy may also be performed to remove an area of focal degeneration from within the tendon. In chronic insertional tendinitis, depending on the findings, the retrocalcaneal bursa is removed, any tears are repaired, degenerated foci excised, and, as required, the calcaneal upper posterior angle is smoothed in order to minimise friction.

Osgood-Schlatter disease and Sever's disease

  • Painful conditions affecting tendon insertion sites (apophysitis) are common in growing athletes.
    • Sever´s disease Painful Conditions of the Ankle and Foot in Children and Adolescents occurs at the Achilles tendon insertion site at the back of the calcaneous. It affects athletes around the ages of 7-11 years, particularly if training takes place on hard surfaces wearing shoes with poor shock-absorbing ability.
    • Osgood-Schlatter disease Knee Complaints in Growing Children is an equivalent condition affecting the tibial tubercle at the time of ossification around the ages of 8-15 years. It is commonly seen in sports that involve a great deal of running, jumping or kicking.
    • Similar sport-specific painful conditions around apophyses may be encountered at several other tendon insertion sites.
  • A general management principle is to avoid pulling or jolting exercises that cause pain to the affected apophysis for as long as the pain is present. It is usually possible to exercise in modes that cause no pain or to take some alternative exercise.
  • It may be beneficial to do intensified stretching of the lower limb muscles and to use transferable shock absorbing gel insoles that the patient can use in the heels of all shoes he/she wears.
  • The patient may need a certificate for the school in order to be excused from exercise that causes pain.

Iliotibial band syndrome

  • A painful condition seen in runners caused by the sliding of the iliotibial band over the lateral femoral epicondyle when running leading to friction, which in turn causes tenoperiostitis between the tendon and bone.
  • Iliotibial band syndrome may also be associated with irritation of the pinched synovial plica or bursa.

Symptoms and findings

  • Lateral knee pain is characteristic. Pain usually starts during running and forces the person to stop running. The pain usually resolves at rest but will recur during running. The pain is often worse when running downhill.
  • Physical examination findings are usually sparse, but tenderness is usually present over the iliotibial band at the lateral femoral condyle. Pain can sometimes be elicited if the patient bears his/her weight on a flexed knee.

Treatment

  • Pain may persist for several months, but recovery is usually spontaneous without the need for surgery.
  • Any sport that puts pressure on the knee region, particularly running, must be stopped until the condition improves. Anti-inflammatory medication (topical ointment or oral) may be necessary in the early stage. Glucocorticoid/anaesthetic injections have also been used. No more than a total of three injections should be administered, and an interval of 2 weeks between the injections is recommended. Glucocorticoid injections are not recommended for growing children.
  • Core and pelvic muscle exercises are recommended in order to improve body control, lower limb position as well as technique. In particular, excercises of the abductors and external rotators of the hip are effective in correcting deficits in the lower limb alignment.
  • The iliotibial band attaches proximally to the tensor fasciae latae muscle and the gluteus maximus muscle. If these muscles are tight, massage or stretching can be used to loosen them.
  • Rare, persistent cases may require surgical management, which is performed in accordance with the findings.

Conjoined tendon injury (sports hernia)

  • A microscopic or macroscopic tear of the tendon fibres superior to the inguinal ligament at the common insertion site for the rectus abdominis muscle, the internal oblique abdominal muscle and the transversalis fascia at the pubic tubercle (the upper lateral position).
  • Despite its name, the injury does not result in medial inguinal hernia even though it occurs in the same area.

Symptoms and findings

  • At first, groin pain is present only during quick movements and when straining. Abdominal muscle work produces pain.
    • Pain may radiate, not only to the groin and lower abdomen, but also to the perineum, thigh, lower back, sacrum and buttocks.
  • Point tenderness is noted on palpation of the area superior to the inguinal ligament superolaterally to the pubic bone.
  • Muscle compliance is limited and in some cases a local muscle spasm is noted.
  • Ultrasonography findings are usually normal. MRI should be requested by a specialist in preparation for a surgical intervention. MRI findings include local tissue oedema and macroscopic tendon damage as well as atrophy of the abdominis rectus muscle on the affected side.
  • Differential diagnosis should consider the possibility of more common problems affecting the groin area of athletes, such as tears at other tendon insertion sites and enthesitis, inflammation of the pubic symphysis (osteitis pubis), hip stress fractures and bursitis.

Treatment

  • Initially rest and anti-inflammatory agents. Pain-inducing quick movements and jumps should be avoided.
  • The length of the rest period depends on the sport in question and the severity of symptoms. A rest period of 2-4 weeks from pain-inducing exercises is indicated in the acute phase.
  • After the acute phase, rehabilitation planned and supervised by a physiotherapist should be tried.
  • Chronic sports hernia can be managed surgically. The aim of surgical intervention is to debride and repair both the tendon complex and the insertion site for the inguinal ligament at the symphysis as well as to strengthen the area with a mesh repair.
    • The recovery from surgery will take about 3 weeks. The strength and mobility of muscles must have returned to normal before intense training is recommenced.

Lateral epicondylitis (tennis elbow) and medial epicondylitis (golfer's/pitcher's elbow)

  • Lateral and medial epicondylitis Lateral and Medial Epicondylitis of the Elbow are painful conditions that cause enthesitis type pain. They affect the wrist extensor and flexor tendons inserting at the distal epicondyles of the humerus.
    • Epicondylitis is common among players of racket and throwing sports.
    • Lateral epicondylitis (tennis elbow) is more common than medial epicondylitis.
    • Medial epicondylitis (golfer's/pitcher's elbow) is encountered in sports where powerful and sharp jerking movements are directed to the humeral insertion site for the wrist flexors.
  • Epicondylitis is usually a stress injury when training and playing has been excessive in relation to muscle condition. Excessive squeezing of sports equipment, or using a grip that is too thick, may also result in epicondylitis.

Treatment

  • The aim of treatment is to control the epicondyle pain and inflammation at as early a phase as possible.
    • Acute pain is treated with an ice pack and anti-inflammatory analgesics Non-Steroidal Anti-Inflammatory Drugs (Nsaids) for Treating Lateral Elbow Pain.
    • In general, glucocorticoid injections are not recommended for the treatment of epicondylitis because they increase the recurrence of the pain within a 3-12 month follow-up period despite providing good short-term (less than 6 weeks) pain relief. Glucocorticoid injections are not recommended for growing children.
    • When pain occurs, a break of 1-2 weeks from racket and throwing sports is usually indicated. Moreover, any occupational strain on the arm muscles should be modified: for example, using the computer mouse with the other hand may be necessary for a few months.
    • After the acute phase, the arm muscles are stretched and strengthened using light 1-5 kg weights or a resistance elastic band. Eccentric exercises are also recommended for the treatment of epicondylitis (drop exercises where the concentric phase is omitted, e.g. a weight held in the affected hand holding a weight is assisted by the unaffected hand to its start position from where it is allowed to drop and, for example, hang off the table).
    • A strap/brace that provides slight compression to the muscles of the painful side may promote healing. The strap/brace is applied so that it reaches to about 5 cm from the distal end of the elbow epicondyles. Tennis elbow support straps which incorporate a small air cushion have proved to be the most effective in practice. Short-term use of a wrist splint has been found to be as beneficial as a tennis elbow support strap.
    • Surgery should be considered in recalcitrant cases that have persisted for at least six months, when other properly structured and supervised treatment modalities have been tried.
