ROTATOR CUFF TEARS

Partial-Thickness
Rotator Cuff Tears

A partial-thickness rotator cuff tear means the tendon is damaged but not completely torn through. Many partial tears improve without surgery, while others enlarge over time and eventually require repair.

What Is A Partial-Thickness Tear?

Unlike a full-thickness tear, a partial tear damages only part of the tendon. The remaining fibers continue to attach the tendon to the bone, allowing many patients to maintain good shoulder strength despite significant pain.

Common Symptoms

  • Pain reaching overhead
  • Night pain
  • Pain while lifting
  • Pain throwing
  • Pain with exercise
  • Mild weakness

Common Causes

  • Age-related degeneration
  • Repetitive overhead activity
  • Sports injuries
  • Traumatic injury
  • Shoulder impingement

Does It Need Surgery?

Not necessarily.

Many partial tears improve with physical therapy, activity modification, anti-inflammatory medication, or corticosteroid injection. Surgery is considered when pain persists, function declines, or imaging suggests progression.

Often Treated Without Surgery

  • Small partial tears
  • Good strength
  • Improving symptoms
  • Minimal functional limitation

Reasons To Consider Surgery

  • Persistent pain
  • Failure of therapy
  • High-grade partial tear
  • Progressive weakness
  • Athletes or active patients
  • Tear progression

Can A Partial Tear Become Larger?

Yes. Some partial tears remain stable for years, while others enlarge and eventually become full-thickness tears. Regular evaluation is appropriate when symptoms worsen or strength declines.

Stable Tears

Remain unchanged for years with good shoulder function.

Progressive Tears

Gradually enlarge and become increasingly painful or weak.

Repairable Tears

Early treatment may preserve tendon quality before progression occurs.

Treatment Goals

Pain Relief

Reduce inflammation and improve comfort.

Motion

Restore comfortable shoulder movement.

Strength

Preserve shoulder function and endurance.

Prevent Progression

Identify patients who may benefit from repair before the tear enlarges.
