TENNIS • SHOULDER INJURIES • DIAGNOSIS & RECOVERY
Common Shoulder Injuries in Tennis Players
The tennis shoulder is exposed to repeated high-speed rotation, overhead loading, acceleration, and deceleration. These demands can produce problems involving the rotator cuff, labrum, biceps tendon, capsule, cartilage, and surrounding muscles. The pattern of injury often differs with age, playing level, prior injury, and the amount of tennis being played.
QUICK ANSWER
Common shoulder problems in tennis players include rotator cuff tendinopathy and tears, subacromial bursitis, internal impingement, SLAP and other labral injuries, biceps tendon disorders, shoulder instability, scapular dyskinesis, loss of rotational motion, and arthritis. Younger competitive players more often develop overhead-athlete problems involving instability, the labrum, and internal impingement, while rotator cuff disease and arthritis become increasingly important with age.
Why Tennis Places So Much Stress on the Shoulder
The tennis serve requires the shoulder to move through substantial external rotation and then rapidly accelerate into internal rotation.
After ball contact, the shoulder must also decelerate the arm and racket. This creates demanding concentric and eccentric loads on the rotator cuff and surrounding musculature.
The shoulder may repeat this sequence hundreds of times during practice and competition.
Because tennis is a kinetic-chain sport, deficiencies in the legs, hips, trunk, or scapula can also change the forces experienced by the shoulder.
Repetition
High serving and stroke volume can progressively fatigue the muscles that stabilize the shoulder.
Extreme Motion
The cocking phase requires substantial external rotation and precise dynamic joint control.
High Force
Acceleration and deceleration generate large forces across the rotator cuff, labrum, capsule, and biceps-labral complex.
1. Rotator Cuff Tendinopathy
Rotator Cuff Overload
The rotator cuff helps keep the humeral head centered in the socket throughout the tennis stroke. These muscles are especially important during the cocking, acceleration, and deceleration phases of the serve.
When serving volume or intensity exceeds the cuff's current capacity, the tendon can become painful even without a major tear.
Symptoms often include lateral shoulder pain, discomfort with overhead strokes, soreness after prolonged play, and reduced endurance.

2. Partial-Thickness Rotator Cuff Tears
Partial Rotator Cuff Tearing
Partial-thickness tears involve damage to only part of the tendon. They can occur on the bursal surface, within the tendon, or on the articular side facing the joint.
In overhead athletes, articular-sided partial tears may occur in association with internal impingement and repetitive high-velocity loading.
Not every partial tear requires surgery. Symptoms, weakness, tear depth, age, playing goals, and response to rehabilitation all matter.
3. Full-Thickness Rotator Cuff Tears
Full-Thickness Tendon Tear
A full-thickness tear extends through the entire depth of a rotator cuff tendon.
These tears become increasingly common as people age and may exist before tennis becomes painful.
Some recreational players continue to play despite a tear, while others develop weakness, night pain, loss of serve velocity, or progressive functional limitations.
The decision between nonsurgical treatment and repair depends on the individual rather than the MRI finding alone.
See playing tennis with a rotator cuff tear for a more detailed discussion.
4. Subacromial Bursitis and Impingement-Type Pain
Bursa and Rotator Cuff Irritation
The subacromial bursa is a thin lubricating structure located above the rotator cuff.
It can become irritated with repetitive overhead loading, particularly when the cuff is fatigued or the shoulder is being asked to tolerate more activity than usual.
Pain is often felt over the outer shoulder and may occur during arm elevation or serving.
The term impingement should not be interpreted as one structure simply being mechanically pinched. Rotator cuff health, strength, scapular mechanics, mobility, and workload can all contribute.
5. Internal Impingement
Posterior Shoulder Pain During External Rotation
Internal impingement occurs when structures inside the shoulder come into contact during the extreme externally rotated position used by overhead athletes.
During late cocking, the undersurface of the posterior rotator cuff can contact the posterior-superior glenoid and labrum.
This contact can occur as part of normal overhead movement. It becomes clinically important when repeated loading is associated with pain, partial cuff injury, labral pathology, instability, or altered shoulder mechanics.

Not Every Abnormality Is a Separate Problem
Overhead-athlete shoulder conditions often overlap. A player with internal impingement may also have posterior shoulder tightness, scapular dyskinesis, subtle instability, a partial rotator cuff tear, or labral changes. The goal is to understand how the findings fit together rather than treating every MRI finding as an isolated diagnosis.
6. SLAP Tears
Superior Labrum Anterior-to-Posterior Injury
The superior labrum surrounds the upper portion of the shoulder socket and is closely related to the origin of the long head of the biceps tendon.
Overhead loading can place repetitive traction and rotational stress on this region.
Symptoms may include deep shoulder pain, clicking, pain during serving, or discomfort in the late cocking position.
However, superior labral abnormalities are common on MRI, particularly with increasing age. A SLAP finding on imaging does not automatically mean that it is the source of the player's pain.
Learn more about SLAP tears in tennis players.
7. Other Labral Tears
Anterior, Posterior, or Combined Labral Injury
Labral tears can occur in multiple regions of the shoulder.
Anterior labral tears frequently occur with traumatic instability. Posterior labral pathology can occur from repetitive loading or trauma, while more extensive tears may involve several regions.
Symptoms can include deep pain, catching, clicking, instability, or reduced confidence during high-speed strokes.
8. Long Head of the Biceps Tendon Problems
Biceps Tendinopathy or Biceps-Labral Pain
The long head of the biceps travels through the front of the shoulder before attaching near the superior labrum.
Repetitive overhead activity can irritate the tendon itself or the biceps-labral complex.
Players may notice pain toward the front of the shoulder, particularly during acceleration or overhead strokes.
Biceps pathology often exists alongside rotator cuff or labral disease rather than occurring in isolation.
9. Shoulder Instability
Traumatic or Repetitive Instability
Instability means that the humeral head moves excessively relative to the glenoid.
This may occur after a traumatic dislocation, but instability can also be more subtle.
Some tennis players describe apprehension, slipping, fatigue, loss of control, or pain when the arm reaches the externally rotated serving position.
Younger athletes with previous dislocations deserve particular attention because recurrent instability can produce progressive damage to the labrum, cartilage, or bone.
Learn more about shoulder instability in tennis players.
10. GIRD and Posterior Shoulder Tightness
Glenohumeral Internal Rotation Deficit
Overhead athletes frequently develop differences between the dominant and nondominant shoulders.
The serving arm may gain external rotation and lose some internal rotation.
This adaptation is not inherently abnormal. The important question is whether internal rotation loss is excessive and associated with symptoms, altered mechanics, or loss of total rotational motion.
Clinically significant posterior shoulder tightness can influence the way the humeral head moves during the serve.
11. Scapular Dyskinesis
Altered Scapular Motion
The glenoid socket is part of the scapula, so the position and movement of the scapula directly influence shoulder mechanics.
Fatigue, weakness, pain, muscle imbalance, or kinetic-chain dysfunction can change scapular movement during the serve.
Scapular dyskinesis is not necessarily an injury by itself. Some athletes have altered scapular motion without symptoms.
When it is clinically relevant, improving scapular strength, endurance, and coordination can be an important part of treatment.
Read more about scapular dyskinesis in tennis players.
12. AC Joint Problems
Acromioclavicular Joint Irritation or Arthritis
The acromioclavicular joint is located at the top of the shoulder where the clavicle meets the acromion.
Pain from this joint is typically localized directly over the top of the shoulder.
It may become symptomatic with age, prior injury, weight training, or repetitive loading.
Cross-body positions can be particularly uncomfortable.
13. Glenohumeral Arthritis
Shoulder Arthritis
Glenohumeral arthritis becomes an increasingly important source of shoulder pain among older tennis players.
Common symptoms include stiffness, deep joint pain, grinding, progressive loss of rotation, and difficulty generating a smooth serve.
Some players continue recreational tennis despite substantial arthritis, while others become limited by pain and motion loss.
14. Acute Traumatic Injuries
Falls, Dislocations, Fractures, and Acute Tears
Not all tennis injuries are caused by overuse.
Players can fall while changing direction, dive for a ball, collide with another player, or sustain a sudden forceful movement.
Acute injuries can include:
- Shoulder dislocation
- AC joint separation
- Clavicle fracture
- Proximal humerus fracture
- Acute rotator cuff tear
- Labral injury
Significant trauma followed by deformity, inability to lift the arm, severe weakness, or persistent pain should be evaluated promptly.
How Age Changes the Likely Diagnosis
The same symptom can mean different things in different age groups.
Younger Competitive Players
- Instability
- Labral injuries
- Internal impingement
- Posterior shoulder tightness
- Scapular dysfunction
- Overuse-related cuff symptoms
Older Recreational Players
- Rotator cuff tendinopathy
- Partial or full-thickness cuff tears
- Biceps pathology
- AC joint arthritis
- Glenohumeral arthritis
- Combined degenerative conditions
Can Several Problems Exist at the Same Time?
Yes, and this is extremely common.
A player may have rotator cuff tendinopathy together with biceps irritation and scapular weakness. Another may have a partial cuff tear, posterior shoulder tightness, and internal impingement.
Older players frequently have several age-related MRI findings at the same time.
The clinical challenge is determining which findings are actually driving the symptoms.
Do Not Treat the MRI Instead of the Player
MRI is extremely useful when appropriately indicated, but abnormal findings do not always equal symptomatic disease. Labral changes, rotator cuff abnormalities, and arthritis may exist even in people who function well. Imaging should be interpreted together with the history, examination, strength, motion, symptoms, and athletic demands.
How Are Tennis Shoulder Injuries Evaluated?
A useful evaluation begins by understanding exactly how the symptoms behave.
Important questions include:
- Was the onset sudden or gradual?
- Where is the pain located?
- Which stroke causes pain?
- Does serving hurt more than groundstrokes?
- At what phase of the serve does pain occur?
- Is there weakness?
- Is there instability or apprehension?
- Is there clicking or catching?
- Is there night pain?
- Has motion changed?
- Has tennis volume recently increased?
The physical examination can then assess rotator cuff strength, range of motion, stability, the biceps-labral complex, AC joint, scapular mechanics, and other possible pain generators.
When Is Imaging Useful?
Imaging depends on the suspected injury.
X-rays are particularly useful for arthritis, fracture, bone alignment, and certain chronic structural changes.
Ultrasound can evaluate the rotator cuff dynamically in selected situations.
MRI is often useful when there is concern for rotator cuff tearing, labral pathology, instability-related injury, or another significant soft-tissue problem.
Not every tennis player with shoulder pain needs an MRI.
How Are Tennis Shoulder Injuries Treated?
Treatment depends on the diagnosis, but many tennis-related shoulder conditions can initially be treated without surgery.
A nonsurgical program may include:
- Temporary reduction in serving or playing volume
- Rotator cuff strengthening
- Scapular stabilization and endurance
- Mobility work when a meaningful restriction is present
- Thoracic and kinetic-chain rehabilitation
- Progressive tennis-specific loading
- Serve-mechanics modification when appropriate
- Anti-inflammatory treatment when appropriate
- Selective use of injections for specific conditions
When Is Surgery Considered?
Surgery is not based simply on the presence of an abnormal MRI.
It may be appropriate when there is a structural problem unlikely to recover adequately without repair or reconstruction, or when a well-designed nonsurgical program has failed to restore acceptable function.
Examples can include certain traumatic rotator cuff tears, recurrent instability, selected labral injuries, advanced arthritis, or persistent symptomatic rotator cuff disease.
The appropriate operation—and whether surgery is appropriate at all—depends on the specific athlete and diagnosis.
When Should a Tennis Player Seek Evaluation?
Shoulder evaluation is particularly reasonable when there is:
- Persistent pain despite reducing activity
- Progressive weakness
- Night pain
- Loss of motion
- Instability or apprehension
- Recurrent clicking associated with pain
- Loss of serve velocity or control
- An acute traumatic injury
- Symptoms that repeatedly return with tennis
The Goal Is Not Simply to Eliminate Pain
For an athlete, successful treatment should ideally restore the capacity to tolerate the demands of tennis. That means addressing the injured tissue while also rebuilding strength, endurance, mobility, kinetic-chain function, and progressive exposure to the specific strokes the player wants to perform.
Frequently Asked Questions
What is the most common shoulder injury in tennis?
Rotator cuff overload and tendinopathy are common, but the most likely diagnosis depends heavily on age and playing level. Younger competitive players may be more prone to instability, labral problems, and internal impingement, while rotator cuff tears and arthritis become more common with age.
Can tennis cause a rotator cuff tear?
Repeated overhead loading can contribute to rotator cuff pathology, but many tears develop through a combination of aging, tendon degeneration, anatomy, cumulative use, and sometimes trauma. Tennis may make a previously asymptomatic tear become symptomatic.
Can tennis cause a labral tear?
Repetitive overhead loading can stress the labrum, and traumatic instability can also produce labral injury. However, labral changes can be present without symptoms, so MRI findings need to match the clinical picture.
Do most tennis shoulder injuries require surgery?
No. Many overuse-related shoulder problems improve with load modification, rehabilitation, strengthening, mobility work, and a gradual return to tennis. Surgery is reserved for selected structural problems or persistent symptoms that do not respond adequately to appropriate nonsurgical care.
Can I keep playing if I have a shoulder injury?
Sometimes. Whether continued tennis is reasonable depends on the specific injury, pain level, strength, stability, playing demands, and whether symptoms are worsening. Continuing unrestricted play through progressive weakness, instability, or increasing pain is less appropriate.
