Rotator Cuff Injury Prognosis: Recovery Factors & Treatment Pathways

Rotator cuff tear outcomes depend on tear characteristics, patient factors, and treatment selection. Most patients achieve functional improvement with appropriate management.

Prognostic Factors

Factor	Favorable	Unfavorable
Tear acuity	Acute traumatic	Chronic degenerative
Tear size	Partial/small (<1cm)	Massive (>5cm, 2+ tendons)
Retraction	Minimal	Medial to glenoid
Muscle quality	Minimal fatty infiltration (Goutallier 0-1)	Advanced fatty infiltration (3-4)
Age	<50	>65
Smoking	Non-smoker	Current smoker
Comorbidities	None	Diabetes, thyroid, CVD

Treatment Pathways

• Nonoperative (first-line for most): PT (scapular stabilization, rotator cuff strengthening), NSAIDs, activity modification, subacromial injection — 75% improve.
• Operative: Arthroscopic repair (single/double row), patch augmentation, superior capsular reconstruction, reverse TSA for irreparable + arthritis.
• Timing: Acute traumatic tears → early repair (≤6 wks). Chronic → 3–6 mo PT trial first.

Surgical Risks

• Stiffness (10–20%), re-tear (5–40% size-dependent), infection (<1%), nerve injury (<1%), CRPS.
• Rehab: 4–6 mo to full recovery; 12 mo for maximal improvement.

Key Message

Even "failed" repairs often improve function vs. preoperative baseline. Shared decision-making incorporating tear MRI features, patient goals, and surgeon expertise optimizes outcomes.
