Shoulder Arthroscopy: What to Expect Before, During, and After

From rotator cuff tears to labral damage and shoulder instability, arthroscopy has become the go-to approach for treating a wide range of shoulder problems. Here's a complete guide to what the surgery involves and what recovery really looks like.

What Is Shoulder Arthroscopy?

Shoulder arthroscopy is a minimally invasive surgical technique used to diagnose and treat problems inside the shoulder joint through a few small incisions rather than one large open cut. The shoulder is the most mobile joint in the body — which also makes it one of the most prone to injury and instability. A thin instrument called an arthroscope, equipped with a camera and light, lets the surgeon see directly inside the joint on a monitor and address damage with precision, often in the same sitting as the diagnosis.

What Conditions Does Shoulder Arthroscopy Treat?

• Rotator cuff tears
• Labral tears, including SLAP tears and Bankart lesions from dislocations
• Shoulder impingement syndrome
• Frozen shoulder (adhesive capsulitis) that hasn't responded to therapy
• Recurrent shoulder instability or dislocation
• Bone spurs or inflamed tissue causing pain with overhead movement

Common Signs You Might Need Shoulder Arthroscopy

• Persistent shoulder pain that hasn't improved with rest or physical therapy
• A feeling of instability, as though the shoulder might "pop out"
• Weakness or pain when lifting the arm overhead
• Clicking, catching, or grinding sensations during movement
• Stiffness that limits your normal range of motion

How the Surgery Works

1. Anesthesia. A nerve block combined with general anesthesia or sedation is typically used, so the shoulder and arm stay numb well after you wake up.
2. Patient positioning. You'll be positioned either in a semi-reclined "beach chair" position or lying on your side, depending on the surgeon's preference and the specific repair planned.
3. Small portals. A few small incisions are made around the shoulder to allow the arthroscope and instruments access to the joint.
4. Fluid expansion. Sterile saline is used to gently expand the joint space, improving visibility for the surgical team.
5. Diagnosis and repair. The surgeon examines the rotator cuff, labrum, and surrounding structures, then repairs torn tissue, removes bone spurs, or stabilizes the joint as needed using the same small incisions.
6. Closing up. The portals are closed with a stitch each, and a supportive dressing or sling is applied. Most procedures take about 45 minutes to just over an hour.

Recovery: What to Expect

• Same day: Most patients go home the same day, with the arm supported in a sling.
• First 2–4 weeks: The sling protects the repair while gentle, passive range-of-motion exercises begin under guidance.
• 4–8 weeks: Active exercises gradually rebuild motion, with strengthening introduced as healing progresses.
• 3–6 months: Most patients regain functional strength and range of motion for daily activities; a full return to sport or overhead work can take longer for larger repairs.

Risks and Considerations

• Stiffness of the shoulder if rehabilitation is delayed or skipped
• Infection, though rare given the small incision size
• Nerve irritation causing temporary numbness or tingling in the arm
• Re-tearing of repaired tissue, more likely with larger or older injuries
• Incomplete relief if damage was more extensive than initially seen on imaging

Tips for a Smooth Recovery

• Wear your sling consistently, especially in the first few weeks when the repair is most vulnerable.
• Attend physiotherapy sessions as scheduled — gentle, guided motion is what prevents stiffness.
• Ice the shoulder regularly to manage swelling and discomfort in the early days.
• Avoid reaching overhead or lifting anything heavy until your surgeon clears you to do so.
• Give strength gains time — motion typically returns before strength does.

The Takeaway

Shoulder arthroscopy has made it possible to treat a wide range of shoulder problems — from labral tears to impingement to instability — with far less trauma to the joint than traditional open surgery. Recovery still takes real time and disciplined rehabilitation, but most patients return to their normal activities with significantly less pain and better function. If shoulder pain or instability is holding you back, an orthopedic evaluation can help determine whether arthroscopy is the right path forward.
