🔎 What Is Subacromial Decompression?

Subacromial decompression (SAD) is a surgical procedure designed to relieve pain caused by shoulder impingement or bursitis. It involves removing inflamed bursal tissue and reshaping the underside of the acromion (part of the shoulder blade) to create more space for the rotator cuff tendons.

This procedure is typically done arthroscopically and is sometimes combined with other procedures—most commonly rotator cuff repair (RCR). Recovery pathways differ significantly depending on whether the SAD was done alone or in combination with a repair.

🗓️ Recovery Timeline After Subacromial Decompression

⚠️ Please note: These timelines are for standalone SAD procedures. If you also had a rotator cuff repair or other procedure, your rehab plan will likely be more protective—always follow your surgeon’s instructions.

✅ Week 1–2: Pain Control & Gentle Movement

• Pain: Common, especially at night. Managed with prescribed medication and icing.
• Sling: Often used for comfort, but not typically required full-time for standalone SAD.
• Physio: It’s usually safe and beneficial to begin physiotherapy in the first week to reduce stiffness and guide early movement—unless your surgeon advises otherwise.
• Focus: Gentle pendulum exercises, passive movement, and maintaining neck and upper back mobility.

✅ Week 3–6: Regaining Movement

• Pain: Improving but still present during certain activities.
• Goal: Regain active and passive shoulder range of motion and restore normal movement patterns.
• Caution: Avoid pushing through sharp pain or forcing range too early.

✅ Week 6–12: Building Strength

• Recovery variability: Progress during this stage can vary widely depending on pain, surgical findings, and pre-surgical conditioning.
• Focus: Begin strengthening rotator cuff and scapular muscles with light, guided exercises.
• Work & sport: Return-to-work or sport during this phase should be based on functional capacity—not a set timeline.

🔸 Your physiotherapist will help assess your strength, movement control, and readiness before progressing to heavier loads or more complex movements.

✅ Months 3–6: Returning to Function

• Progress: Many patients experience improved range and strength by this point—but not all recover on the same timeline.
• Goal: Gradually reintroduce higher-level tasks, including sport-specific drills, overhead work, or manual labour.
• Return-to-work/sport: Highly variable and depends on your goals, shoulder control, and comfort. Some may resume normal activity sooner, while others may require longer.

🔸 Functional milestones are more important than the calendar. Your physiotherapist will guide you based on individual progress and surgical input.

🧠 Why Physiotherapy Is Crucial After SAD

While surgery creates space in the shoulder, it doesn’t resolve movement dysfunction or muscle weakness. That’s where physiotherapy comes in.

A targeted post-op rehab program helps by:

• Restoring normal joint mechanics and shoulder rhythm
• Reducing muscle guarding and compensations
• Building safe, progressive load tolerance
• Preventing long-term issues like frozen shoulder or re-irritation

Without rehab, many patients continue to experience pain, weakness, or limited function despite a technically successful operation.

⚠️ What If You’re Still in Pain After Surgery?

Not all recoveries are straightforward. Some reasons for prolonged pain or poor recovery include:

• Incomplete resolution of inflammation or bursitis
• Early development of frozen shoulder (adhesive capsulitis)
• Poor rotator cuff recruitment or scapular control
• Post-operative stiffness or scarring
• Overuse or premature return to activity

In some cases, further imaging or surgical review may be needed—but often, a reassessment and tailored physiotherapy program can make a significant difference.

🏋️‍♀️ Rehabilitation Phases After Subacromial Decompression

Rehabilitation should follow a phase-based, personalised approach. The timing and content should be guided by your individual goals, surgical details, and response to movement.

Phase	Focus
Weeks 1–2	Pain management and gentle mobility under supervision
Weeks 3–6	Improving range of motion and movement coordination
Weeks 6–12	Developing foundational strength and endurance
Months 3–6	Restoring full functional capacity for work, life, and sport

🔸 Exercise selection should always be tailored to your presentation and guided by your physiotherapist in line with your surgeon’s protocol.

🎯 Key Takeaway

Subacromial decompression can reduce pain and improve function—but surgery is just one part of the solution.

A thoughtful, evidence-based rehabilitation plan is critical to your long-term success. And because recovery is highly individual, working with a physiotherapist who understands post-operative shoulder rehab makes all the difference.
