Subacromial Decompression Exercises: Post-Surgery Recovery Guide

Subacromial decompression (also called acromioplasty) creates more space under the acromion bone to reduce impingement of the rotator cuff. Unlike rotator cuff repair, there's no tendon healing required, so recovery is typically faster. However, proper rehabilitation is still essential for the best outcome.

Understanding Your Surgery

What Was Done

During subacromial decompression:

• Bone spurs removed from underside of acromion
• Inflamed bursal tissue removed (bursectomy)
• Space created for rotator cuff tendons
• May include coracoacromial ligament release

What Was NOT Done

• Rotator cuff tendons were not repaired
• No tendon-to-bone healing required
• Faster recovery than rotator cuff repair

Why Rehab Matters

Even without tendon repair:

• Surgery creates inflammation that must resolve
• Muscles have been weakened by pre-surgery impingement
• Movement patterns need correction
• Strength must be rebuilt
• Scapular mechanics need optimization

Recovery Timeline

• Weeks 1-2: Pain management, gentle motion
• Weeks 2-4: Restore range of motion
• Weeks 4-8: Active strengthening
• Weeks 8-12: Progressive resistance
• 3-4 months: Return to most activities

Key advantage: No tendon healing means faster progression than rotator cuff repair.

Phase 1: Early Recovery (Weeks 1-2)

Addressing Scapular Dyskinesis

Many patients with impingement have poor scapular mechanics. Address this:

Key Exercises:

• Lower trap strengthening (Y raises)
• Serratus anterior (push-up plus)
• Middle trap (T raises, rows)
• Scapular awareness drills

Postural Correction:

• Avoid rounded shoulders
• Chin tucks
• Scapular retraction breaks at desk

Return to Activity Guidelines

Light Daily Activities: 2-4 weeks

• Dressing, grooming, light kitchen tasks

Driving: 1-2 weeks (when off narcotic pain meds)

Desk Work: 1-2 weeks

Light Exercise: 4-6 weeks

• Stationary cycling, walking

Swimming: 6-8 weeks

Golf: 6-8 weeks

• Start with putting/chipping

Tennis: 8-12 weeks

Overhead Sports: 10-12 weeks

Weightlifting (Full): 8-12 weeks

• Progress gradually

Common Mistakes

1. Progressing too slowly — Unlike rotator cuff repair, can move faster
2. Neglecting scapular work — Root cause of impingement
3. Only doing rotator cuff exercises — Need comprehensive program
4. Poor posture — Perpetuates impingement
5. Returning to aggravating activities without addressing mechanics

What If Pain Persists?

If significant pain continues beyond 8-12 weeks:

• Residual bursitis
• Underlying rotator cuff tear (may not have been seen)
• Inadequate decompression
• Other shoulder pathology
• Discuss with surgeon

Comparison: Decompression vs. Rotator Cuff Repair

| | Decompression | Rotator Cuff Repair | |---|---|---| | Sling use | Days (comfort) | 4-6 weeks | | Active motion | Weeks 1-2 | Weeks 6-8 | | Strengthening | Weeks 2-4 | Weeks 12+ | | Full activity | 3-4 months | 6-12 months |

Key Takeaways

1. No tendon healing needed — Faster progression than rotator cuff repair
2. Start moving early — Range of motion from day 1
3. Address the root cause — Scapular mechanics and posture
4. Strengthen comprehensively — Rotator cuff AND scapular muscles
5. Expect 3-4 month recovery — Full return to most activities
6. Don't ignore persistent pain — May indicate other issues

Subacromial decompression surgery has a high success rate when combined with proper rehabilitation. The key is not just relieving impingement through surgery, but correcting the movement patterns and strength deficits that contributed to impingement in the first place. Commit to the rehabilitation program, address scapular mechanics, and you'll have the best chance of a pain-free, fully functional shoulder.
