DEFINITION

Team physicians often treat injured active patients aged 50 yr and older. There are various definitions of master athletes. For the purpose of this document, master athletes will be defined as active individuals aged 50 yr or older. They desire optimal levels of performance or wish to exercise for general health and have high expectations for sports medicine care, including return to sport or activity. In addition, to the more common general illnesses and injuries seen in athletes, master athletes can experience specific illnesses and injuries owing to their physiology. This may require customized treatment to address the complexity of these conditions. This document will examine selected illnesses and injuries commonly seen in master athletes.

GOAL

The goal of this document is to help the team physician improve the care of the master athlete by understanding medical and musculoskeletal factors common in this age group. To accomplish this goal, the team physician should have knowledge of and be involved with the following:

  • physiological considerations, including cardiopulmonary function, muscle strength, and balance;
  • medical considerations, including preparticipation evaluation and cardiovascular disease; and
  • musculoskeletal considerations, including Achilles tendon rupture, lateral elbow and rotator cuff tendinopathy, lumbar spinal stenosis, and shoulder, hip, and knee arthritis.

SUMMARY

This document provides an overview of selected medical issues that are important to team physicians who are responsible for the care and treatment of athletes. It is not intended as a standard of care and should not be interpreted as such. This document is only a guide and, as such, is of a general nature, consistent with the reasonable, objective practice of the health care profession. Adequate insurance should be in place to help protect the physician, the athlete, and the sponsoring organization.

This statement was developed by a collaboration of six major professional associations concerned about clinical sports medicine issues; they have committed to forming an ongoing project-based alliance to bring together sports medicine organizations to best serve active people and athletes. The organizations are the American Academy of Family Physicians, American Academy of Orthopaedic Surgeons, American College of Sports Medicine, American Medical Society for Sports Medicine, American Orthopaedic Society for Sports Medicine, and American Osteopathic Academy of Sports Medicine.

MEDICAL CONSIDERATIONS FOR THE MASTER ATHLETE

Physiology

General considerations

  • There are physiological changes that occur with aging, which include the following:
    • ○Cardiopulmonary (cardiac output, blood pressure, V˙O2max, vital capacity)
    • ○Musculoskeletal (reaction time, strength, muscle endurance, tendon structure, cartilage structure, bone mass, flexibility, fat-free body mass, balance)
    • ○Metabolic (glucose tolerance, lipids, insulin sensitivity, metabolic rate)
  • Physiological changes may be associated with many chronic conditions, such as diabetes, coronary artery disease, hypertension, osteoarthritis, bone loss, and overweight/obesity.
  • Exercise may modify age-related changes.
  • Medications used by master athletes may have significant adverse effects.

Strength

General considerations

  • Independent of activity level, muscle mass declines with age; approximately 1.25%·yr−1 after age 35 yr.
  • Muscle mass is directly related to peak strength but not necessarily to performance.
  • There is an accelerated decline in peak strength after age 70 yr.
  • Muscle power is lost at a greater rate than endurance capacity.
  • Rates of decline of strength and performance are similar between men and women.
  • There are genetic, chronologic, hormonal, nutritional, and behavioral (exercise) components to muscle aging.
  • Resistance training (RT) may modify age-related changes.

Physiology/pathophysiology

  • Decrease in strength is due to:
    • ○Decreased cross-sectional area (CSA) of type II (fast-twitch) muscle fibers (quality and quantity). With aging, the ratio of the CSA of type II to type I changes from 1:1 to 1:2
    • ○Decrease in contractile rate of force development, the ability to rapidly reach a given magnitude of muscle force during the initial phase of rising muscle force.
  • Sarcopenia, age-associated loss of muscle mass, is usually characterized by the replacement of muscle fibers with fat and fibrosis.
    • ○Contributing factors include disuse, metabolic, neuromusculoskeletal, and neurovascular conditions.
    • ○Associated with functional decline often manifest in decreased knee extensor strength, postural imbalance, and decreased ability to safely navigate stairs and chairs.
    • ○Increased fat infiltration is associated with glucose intolerance, diabetes mellitus, poor knee extensor strength, decreased muscle contractility, muscle fiber recruitment, and muscle metabolism.

Treatment

  • Age-related declines in strength can be delayed or diminished by consistent RT that slows the decline of muscle mass and strength more effectively than aerobic training (AT).
  • The effects of consistent RT include the following:
    • ○Delayed type II muscle fibers changes
    • ○Increases in muscle strength
    • ○Greater power per muscle volume
  • Other effects of consistent RT:
    • ○Decline in fat-free mass, increase in total body mass, reduction in oxidative stress
    • ○Increased basal metabolic rate
    • ○Improved insulin sensitivity and glycemic control
    • ○Increase in bone mineral density

It is essential that the team physician understand:

  • There is an age-related decline in muscle mass and strength.
  • RT modifies these declines, and this should be recommended.
  • RT also modifies effects of other age-related medical conditions.

It is desirable that the team physician

  • Understand and implement an RT program

Cardiovascular Considerations

General considerations

  • Regular exercise (aerobic, strength) may lower risk of fatal and nonfatal myocardial infarction, hypertension, and atherosclerotic heart disease.
  • However, vigorous physical exertion may trigger myocardial infarction or sudden cardiac death in individuals with underlying heart disease.
  • The risk of sudden death associated with high-intensity exercise is imprecise, but it increases with age.
  • The benefits of regular exercise outweigh the risks.
  • Treatment should be individualized based on cardiac condition.
  • Use of cardiac medications is common in this age group.
    • ○Medications can affect physical and cognitive performance; adverse effects should be considered.
    • ○Athletes on anticoagulant medication should be counseled about the risks of sports participation, particularly contact and/or collision sports.
  • Consistent RT may have a beneficial effect on cardiovascular health.

Physiology

  • Age-related changes include the following:
    • ○Increased peripheral vascular resistance; regular exercise decreases peripheral vascular resistance
    • ○Decreased V˙O2max
      • ▪V˙O2max declines at the rate of about 10% per decade beyond age 25 yr; it declines steeply after age 60 yr.
      • ▪With regular exercise, the decline may be as much as half the rate in master athletes as compared with nonathletes.
    • ○Decreased cardiac output; exercise lessens this decrease
    • ○Decreased ventilatory anaerobic threshold; exercise lessens ventilatory anaerobic threshold decrease
  • The effects of consistent RT on cardiovascular physiology include the following:
    • ○Decreased blood pressure
    • ○Decreased resting HR
    • ○Improved left ventricular function

Cardiovascular conditions

Sudden cardiac death
  • Most sudden cardiac death is caused by atherosclerotic CAD.
  • Other less common conditions that predispose to sudden death include the following:
    • ○Hypertrophic cardiomyopathy (HCM)
    • ○Valvular heart disease
    • ○Dilated cardiomyopathies
    • ○Myocarditis
    • ○Dysrhythmias and conduction abnormalities
  • Refer to "Mass participation event management for the team physician: a consensus statement" [Med Sci Sports Exerc. 2004;36(11):2004-8] for equipment and medical supplies related to arrhythmias and managing individuals presenting with sudden cardiac arrest.
Atherosclerotic CAD
  • The most common cardiac disease in this age group and major risk factor for angina, myocardial infarction, and arrhythmia.
  • Acute myocardial infarction occurs in individuals even with minimal coronary artery stenosis.
Treatment
  • Individuals with documented CAD (>50% narrowing if angiography has been performed) should not participate in high-intensity sports/activities without further consultation because of increased risk of myocardial infarction and sudden cardiac death.
Hypertension
  • Prehypertension (120-139/80-89 mm Hg)
  • Stage 1 hypertension (140-159/90-99 mm Hg)
  • Stage 2 hypertension (>160/>100 mm Hg)
  • Incidence increases with age
Treatment
  • Athletes with prehypertension and stage 1 hypertension in the absence of target organ damage should not be restricted from participation in master activities.
  • Athletes with stage 2 hypertension should be restricted from static high-resistance sports (e.g., weight training) and should likely be restricted from high-intensity sports until their blood pressure is normalized.
Congenital and valvular heart disease conditions
  • HCM
    • ○See page 2062, "Selected issues in injury and illness prevention and the team physician: a consensus statement" [Med Sci Sports Exerc. 2007;39(11):2058-68].
    • ○Heterogeneous disorder, in which there is an imprecise means of stratifying risk.
  • Dilated cardiomyopathy or arrhythmogenic right ventricular dysplasia
  • Mitral valve prolapse (MVP)
Treatment
  • Athletes with definitive diagnosis of HCM should be advised to avoid participation in high-intensity sports.
  • Individuals with dilated cardiomyopathy or arrhythmogenic right ventricular dysplasia should be restricted from high-intensity sports.
  • Most athletes with MVP can participate on an unrestricted basis.
    • ○Individuals with the following criteria should be restricted to low-intensity sport
      • ▪History of syncope likely secondary to arrhythmia related to MVP
      • ▪Family history of sudden death due to MVP
      • ▪Exercise-induced repetitive supraventricular or complex ventricular arrhythmias
      • ▪Moderate to severe mitral regurgitation
Arrhythmias
  • Supraventricular
    • ○Atrial fibrillation is the most common arrhythmia.
    • ○Vigorous exertion and endurance training have been reported to increase atrial fibrillation.
  • Ventricular arrhythmia is the most common cause of death in those with HCM.
Treatment
  • Individuals with controlled atrial fibrillation can participate in sport or activity.

Evaluation

  • Refer to Table 1.
  • Moderate- to high-risk profiles for CAD include men older than 40 yr and women older than 50 yr or postmenopausal with one or more independent coronary risk factors (hyperlipidemia or dyslipidemia, systemic hypertension, cigarette smoking, diabetes mellitus, family history of premature CAD). Both should have symptom-limited ECG exercise testing.
T1-26
TABLE 1:
AHA 12 element recommendations for preparticipation cardiovascular screening of competitive athletes.

It is essential that the team physician understand:

  • The most common cause for sudden death in master athletes is atherosclerotic CAD.
  • The indications for exercise ECG testing.
  • The effects and adverse effects of cardiovascular medications on health and performance.
  • When to restrict activity or participation among master athletes with cardiovascular issues.
  • Automatic external defibrillators should be available at all sanctioned masters sporting events, along with personnel trained in cardiopulmonary resuscitation.

It is desirable that the team physician understand:

  • How to manage medications in the master athlete with cardiovascular disease.
  • Age-related cardiovascular determinants of exercise performance, such that guidelines may be given for exercise training.

Preparticipation Evaluation (PPE)

General considerations

  • A PPE should be performed periodically for the athlete who is participating in a vigorous exercise.
  • The PPE should emphasize the cardiovascular, musculoskeletal, and neurologic systems and be specific to both the individual athlete and his/her sport or activities.
  • The primary goal is to identify patients at risk for cardiovascular complications of exercise, especially with occult disease.
  • Other goals include identifying athletes who have relative restriction and need further evaluation/rehabilitation or absolute contraindications.
  • The team physician should provide counsel on selection of appropriate sports/activities.
  • Cardiovascular evaluation includes exercise testing (see Cardiovascular Considerations).
  • Contraindications to exercise testing and/or exercise are given in Table 2.
T2-26

Return-to-play issues

  • See "The team physician and return-to-play issues: a consensus statement" [Med Sci Sports Exerc. 2002;34(7):1212-4].
  • Is the athlete at increased risk for injury or illness?
  • Can this risk be modified to make it acceptable (protective equipment, rehabilitation, medication)?
  • Are other participants at risk for injury or illness because of the problem?

It is essential that the team physician understand:

  • The primary purpose of the PPE is to identify patients at risk for cardiovascular complications of exercise, especially with occult cardiac disease.
  • The PPE should emphasize the cardiovascular, musculoskeletal, and neurologic systems and be specific to both the individual athlete and his/her sport or activities.
  • Perform a history and physical that clears the athlete for participation or identifies need for further evaluation or referral.

It is desirable that the team physician understand:

  • Preventive screening for chronic disease in the older athlete.
  • Coordinate a multidisciplinary team to care for the master athlete.
  • Additional testing to evaluate fitness and exclude cardiovascular disease, major musculoskeletal deficiencies, and neurologic/balance issues.

MUSCULOSKELETAL CONSIDERATIONS FOR THE MASTER ATHLETE

Achilles Tendon Ruptures

Etiologic factors

  • Age: There is a higher incidence older than 45 yr
  • Fluoroquinolones: FDA Black Box Warning of increased risk
  • Activity: Sudden changes in intensity of eccentric athletic activity, which result in tensile overload
  • Tendon degenerative changes include the following:
    • ○Decreased tensile strength and increased stiffness
    • ○Decreased number of Golgi tendon receptors, which results in altered force regulation feedback to muscle

Clinical presentation

  • There are minimal prodromal symptoms. Painful Achilles tendons rarely rupture.
  • Acute presentation
    • ○Pop/snap (sensation of being struck) on sudden eccentric loading, in acceleration, deceleration
    • ○Impaired ability to walk, to raise up on toes, or to run
    • ○Physical examination
      • ▪Palpable defect in tendon in the midsubstance or at the distal insertion. Must differentiate this from proximal muscle tendon junction injury.
      • ▪Thompson test (lack of passive foot plantarflexion with gastrocnemius squeeze) is diagnostic.
  • Delayed presentation
    • ○History of injury and subsequent impaired performance in running, jumping, and stair climbing
    • ○Physical examination
      • ▪Findings include point tenderness with thickened tendon or palpable defect as well as calf atrophy and strength deficit.
      • ▪Positive Thompson test

Imaging

  • Plain x-rays: Evaluate for calcific enthesopathy
  • Magnetic resonance imaging (MRI) or ultrasound: Rarely needed in acute cases, may be useful in chronic cases

Treatment

  • Nonoperative
    • ○Casting is rarely indicated.
    • ○Functional bracing: Non-weight bearing for 2-3 wk followed by gradual protected weight bearing.
      • ▪Prohibit dorsiflexion
      • ▪Progressive institution of rehabilitation
    • ○Casting or bracing are ineffective for chronic ruptures.
  • Operative
    • ○Open repairs with/without augmentation
    • ○Early intervention (within 2 wk) is optimal.
    • ○For chronic tears, open repair with allograft augmentation is preferred.
  • Outcomes
    • ○Functional bracing versus operative both have similar high rates of initial tendon healing.
    • ○Retear rate is higher in braced compared with operative.
    • ○Beware of certain complications (wound healing, nerve injury) in operative cases.

Risk reduction

  • Cautious use of fluoroquinolones
  • Maintain muscle strength, balance, and flexibility of the gastroc/soleus complex and the kinetic chain of the lower extremity.
  • Functional conditioning and training
    • ○Balance training
    • ○Eccentric strength training
  • Use caution when transitioning from nonballistic to ballistic activities.

It is essential that the team physician:

  • Know that fluoroquinolones are associated with increased risk of tendon rupture.

      • ▪Viscosupplementation is not FDA-approved: No evidence of efficacy.
      • ▪Glucosamine has not been shown to be effective.
  • Operative
    • ○Arthroscopic

Shoulder Osteoarthritis

Etiologic dactors

  • Age
  • Gender (male > female)
  • Degeneration is most common causation; it is not necessarily associated with athletic activity.
  • After injury
    • ○Fracture
      • ▪Loss of joint congruity
      • ▪Avascular necrosis
    • ○Instability
      • ▪Recurrent dislocations
      • ▪Postsurgical: Overtightening, loss of rotation
    • ○Rotator cuff disease

Treatment

  • In general, shoulder arthritis is well tolerated.
    • ○There is commonly minimal significant load bearing through the joint.
    • ○Many activities of daily living can be achieved through small arcs of motion.
  • Athletes with higher demands may not tolerate arthritis well and may require more customized treatment.

      • ▪No lasting benefit for pain alone
    • ○Arthroplasty
      • ▪Pain relief, increases ROM, increases strength, especially below 90° of abduction
      • ▪Most athletes are unable to return to activities with overhead motions without modification.
        • •Modifications may be necessary in certain sports/activities that require motion above 90°.

It is essential that the team physician:

  • Know clinical presentation of shoulder osteoarthritis.
  • Understand not all shoulder joint pain is due to osteoarthritis.
  • Understand treatment options.
  • Conduct a comprehensive history and physical examination of the shoulder.

It is desirable that the team physician:

  • Implement a treatment program.
  • Understand the pathophysiology of shoulder osteoarthritis.
  • Suggest and implement activity modifications to allow maximum athletic participation within the limits of the arthritis.

Lumbar Spinal Stenosis (LSS)

General considerations

  • Natural history in the absence of medical care has not been well studied.
  • Stenosis (canal narrowing) can be central, lateral recess, neuroforaminal, or a combination.
  • Cause of pain not completely understood. Direct compression of nerve root and disruption of vascular flow hypothesized.

Etiologic factors

  • Age
  • Stenosis is usually caused by degenerative changes (disk bulging and facet and ligament hypertrophy).
    • ○Other etiologies include disk herniation, spondylolisthesis, synovial cyst, and epidural lipomatosis.

Clinical presentation

  • Symptoms
    • ○Neurogenic claudication
      • ▪Classic presentation
      • ▪Radiating pain from the back or buttocks into the lower extremities
      • ▪Occurs with walking and is relieved by sitting or bending forward
    • ○Also occur with prolonged standing
    • ○Include numbness, tingling, fatigue, and weakness
    • ○Vary based on the severity, type, and location of the stenosis (e.g., bilateral vs unilateral lower extremity symptoms and different radicular distributions)
    • ○May wax and wane
    • ○Progression is typically insidious, although rapid progression may occur.
  • Physical examination
    • ○Reproduction of lower extremity symptoms with lumbar extension
    • ○Neurological examination is often normal.
      • ▪May have absent ankle reflexes, a common age-related finding
  • Differential diagnosis includes vascular disease, peripheral neuropathy, hip pathology, myopathy, myelopathy, and rheumatologic disease (e.g., polymyalgia rheumatica).

Imaging/diagnostic studies

  • This is a radiographic diagnosis that must correlate with signs and symptoms.
    • ○21% of asymptomatic people aged 60 yr or older have stenosis by MRI.
  • X-ray: Weight bearing AP and weight bearing lateral flexion/extension views
  • Advanced imaging: Usually MRI; occasionally myelogram/CT
  • EMG, vascular studies, and laboratory tests may also be indicated.

Nonoperative care

  • Appropriate for patients with mild to moderate symptoms or patients who have medical contraindications to surgery
    • ○Does not alter the natural history
    • ○Helps manage symptoms and maintain function
  • Pharmacologic
    • ○Acetaminophen is preferred. If ineffective, consider NSAID with caution.
    • ○Oral corticosteroids with caution
    • ○Opiates sparingly
    • ○Antidepressants and anticonvulsants for neuropathic pain
    • ○Fluoroscopically guided spinal injections used sparingly as an adjunct to treatment
  • Physical therapy
    • ○Directional preference traditionally toward flexion
    • ○Aerobic conditioning, strength, and balance training
  • Lumbar support for comfort only
  • Activity modification usually emphasizing flexion-biased activities (e.g., bicycling vs running)

Operative care

  • Appropriate for patients with severe lower extremity symptoms and/or functional limitations without medical contraindications
  • Decompression via laminectomy is the most frequently performed surgery.
    • ○Fusion has been reserved for cases of stenosis with instability or, in some cases, of scoliosis and stenosis.
    • ○Data on implantable spinous process spacers remain limited.

It is essential that the team physician:

  • Understand the clinical presentation of LSS.
  • Understand the course of LSS is usually insidious and not all cases require surgery.
  • Conduct a history and physical examination of the spine.
  • Understand treatment options.
  • Understand indications and limitations of imaging methods.

It is desirable that the team physician:

  • Interpret imaging.
  • Understand the differential diagnosis of LSS.
  • Understand the diagnostic assessment of LSS.
  • Understand the indications for nonoperative and operative treatment.

Rotator Cuff Tendinopathy/Tear

Etiologic factors

  • Intrinsic
    • ○Decreased tensile strength of the tendons
    • ○Intrinsic tendon degeneration; secondary to apoptosis
    • ○Direct tendon overload mainly presents as articular-sided injuries.
  • Extrinsic
    • ○Compression against adjacent structures: Subacromial space, coracoacromial arch, coracoid
  • In an animal model, extrinsic compression does not cause injury without intrinsic factors.
  • Fluoroquinolones: FDA Black Box Warning

Clinical presentation

  • This presents in a spectrum of tendinopathy, with the end point being tear.
  • Gradual onset of tendinopathy or tear
    • ○History of chronic "tendonitis/bursitis"
    • ○Weakness/fatigue, especially in overhead/forward flexed positions
    • ○Night pain is a dominant feature
  • Acute onset of tear
    • ○Posttraumatic: Most common is fall on outstretched arm
    • ○Marked weakness to attempted forward flexion/abduction
    • ○Night pain
  • Physical examination
    • ○(+/−) Atrophy
    • ○(+) Impingement sign and test (subacromial local anesthetic injection)
    • ○Painful arc of motion
    • ○Muscle weakness or pain inhibition
      • ▪Supraspinatus: Forward flexion, horizontal adduction
      • ▪Infraspinatus: External rotation, especially at 90° of abduction
      • ▪Subscapularis: Lift-off test (limited because of pain), belly press test, bear hug test
      • ▪"Lag" signs: Inability to hold upper extremity in position specific for that muscle

Imaging

  • Imaging findings alone do not dictate treatment.
  • Plain x-rays are routine in evaluation.
    • ○Multiplanar views: True AP (internal and external rotation), axillary, outlet
  • MRI
    • ○Noncontrast MRI: High accuracy in full-thickness tears, size of tear, amount of retraction, and/or atrophy
    • ○MRI arthrogram: Good accuracy in partial-thickness tears and is valuable if other pathology is suspected
    • ○Positive findings may be clinically insignificant.
  • MRI may not be necessary for initial treatment; it is indicated in the presence of significant findings of tear or failure of initial treatment.
  • Diagnostic ultrasound
    • ○May be helpful adjunct, although reliability is ultrasound technician-dependent
  • CT/CT arthrogram
    • ○If MRI contraindicated
    • ○Good to estimate amount of muscle atrophy

Treatment

  • Not all full-thickness tears need surgical treatment; some partial tears may need surgical treatment.
  • Nonoperative
    • ○Pharmacologic
      • ▪Acetaminophen is preferred. If ineffective, consider NSAID with caution.
      • ▪Corticosteroid injections used for short-term symptom relief; no scientific basis for long-term benefit.
    • ○Physical therapy
      • ▪ROM
      • ▪Strengthening of rotator cuff muscle to maximize cocontraction force couples
      • ▪Scapular stabilization
  • Operative
    • ○Indications
      • ▪Tendinopathy/partial-thickness tear not responsive to nonoperative treatment
      • ▪Acute full-thickness tear
      • ▪Chronic full-thickness tear not responsive to nonoperative treatment
    • ○Surgery may be open or arthroscopic
      • ▪For acute full-thickness tears, best results if repaired within the first 3 wk
      • ▪Less successful results with large chronic tears
      • ▪Must address associated intra-articular or extra-articular pathology

It is essential that the team physician:

  • Understand the clinical presentation of rotator cuff tendinopathy and tear.
  • Understand intrinsic and extrinsic pathophysiological factors.
  • Recognize not all full-thickness tears need surgical treatment; some partial tears may need surgical treatment.
  • Understand treatment options.
  • Understand indications and limitations of imaging methods.
  • Conduct a comprehensive history and physical examination of the shoulder.

It is desirable that the team physician:

  • Interpret imaging.
  • Implement a nonoperative treatment program including kinetic chain activation, scapular control, and rotator cuff strengthening exercises.

Lateral Elbow Tendinopathy

Etiologic factors

  • Age
  • Repetitive strain in the tendons-extensor carpi radialis brevis, extensor carpi radialis longus
  • Tendon degenerative changes include the following:
    • ○Decreased tensile strength and increased stiffness
    • ○Cellular changes due to apoptosis
  • Extrinsic overload owing to overuse, especially in pronation
  • Posttraumatic direct blow
  • Fluoroquinolones: FDA Black Box Warning of increased risk

Clinical presentation

  • Pain with wrist dorsiflexion, shaking hands
  • Inability to do pronation activities
  • Pain with tennis strokes, backhand
  • Differential diagnosis include radial nerve entrapment
  • Physical examination
    • ○Point tenderness anterior and distal to epicondyle
    • ○Decreased strength to wrist dorsiflexion
    • ○Pain and/or weakness with resisted supination from a position of pronation
    • ○Occasional radial nerve findings: Tinel sign, weakness
    • ○Weakness in shoulder external rotation

Imaging

  • Imaging findings alone do not dictate treatment.
  • Plain x-rays: AP and lateral
  • MRI: Rarely necessary but can demonstrate tendon damage

Treatment

  • Pharmacologic
    • ○Acetaminophen is preferred. If ineffective, consider NSAID with caution.
    • ○Corticosteroid injections: Used for short-term symptom relief; no scientific basis for long-term benefit
      • ▪Multiple injections should be avoided; may cause tendon degeneration.
      • ▪Single injections may cause subcutaneous fat atrophy and depigmentation.
    • ○Topical nitroglycerin treatment (adverse effects may limit use)
  • Nonoperative
    • ○Flexibility, especially to improve pronation
    • ○Local strengthening, especially cocontractions
    • ○Kinetic chain strengthening, especially shoulder external rotation
    • ○Modification or change in the mechanics of the sport/activity
    • ○Limited literature support for efficacy
      • ▪Modalities: Ultrasound, iontophoresis (some literature benefit)
      • ▪Augmented soft tissue mobilization (some literature benefit)
      • ▪Forearm splint: Decrease wrist pronation/palmar flexion
      • ▪Counterforce brace
      • ▪Autologous blood injections, extracorporeal shockwave, prolotherapy
  • Operative
    • ○Indicated for failed nonoperative care

    • ○Avoid training errors, sudden changes in volume and intensity of wrist/arm activity, especially excessive pronation.
    • ○Optimize the mechanics of the sport/activity.
    • ○Proper equipment and fit
    • ○Upper extremity strengthening

It is essential that the team physician:

  • Understand the etiologic factors in elbow tendinopathy.
  • Understand treatment options.
  • Conduct a comprehensive history and physical examination of the elbow.
  • Understand the complications related to corticosteroid injection.

It is desirable that the team physician:

  • Interpret imaging.
  • Implement a nonoperative treatment program.
  • Understand indications and goals of an operative treatment program.
