Shoulder Arthroscopy

Overview

Shoulder arthroscopy is a surgical technique, not a single operation. The surgeon places a camera and thin tools into the joint through small portals (typically 5-10mm incisions). There is no large open incision. What gets done through the scope depends on the problem. It may be a rotator cuff repair or a labral repair. It may be making more room under the shoulder's bony roof (subacromial decompression). It may be moving the biceps tendon to a new anchor point (biceps tenodesis), or freeing scarred capsule for frozen shoulder. Sometimes the goal is simply to look inside when imaging has not given a clear answer. Compared to open surgery, the scope disturbs less tissue, causes less pain afterward, and shows the whole joint better. The trade-off: some problems are still better fixed through an open incision, and the surgeon makes that call based on what is wrong.

How the Procedure Works

You are under general anesthesia, positioned either sitting upright (beach-chair) or on your side. Usually you also get a nerve block. That is an injection near the neck that numbs the shoulder and eases pain after surgery. A small portal at the back of the shoulder is made first for the camera. One or two more portals at the front and side hold the working tools. The joint is filled with fluid to create working space. The surgeon checks the joint surfaces, labrum, biceps tendon, rotator cuff, and capsule before fixing the problem. The exact repair or cleanup depends on what is found. At the end, the portals are closed with stitches or adhesive strips, and a sling is applied.

When to Consider Shoulder Arthroscopy

Rotator cuff pathology
Partial or full-thickness tears that have not improved with conservative care. Also impingement, where a bony spur narrows the space the cuff tendons glide through.
Labral and instability pathology
Bankart lesions, SLAP tears, or repeated instability where the torn labrum needs to be stitched back to the rim of the socket.
Stiffness
Frozen shoulder (adhesive capsulitis) that has not improved with therapy and injections. Releasing the scarred capsule through the scope restores motion.

Risks & Why We Still Recommend It

Every operation carries risk. This procedure is offered because the condition, when left untreated, can cause symptoms from a problem inside the shoulder that typically worsens over time and can keep you from the activities that matter to you. The decision to proceed weighs the risks of surgery against the limitations the condition places on daily function. Surgery does not remove risk; it addresses a problem that is otherwise progressive. Whether it is appropriate is determined for each patient in consultation with the surgeon.

Before shoulder arthroscopy we discuss infection, bleeding, and nerve injury (above all the axillary nerve, which wraps around the upper arm bone). We also discuss stiffness, failure of repair (the tendon or labrum does not heal to bone), and anesthesia-related risks.

Frequently Asked

questions we hear in clinic

Will I be asleep during the surgery?

Yes. You are under general anesthesia, positioned either sitting upright (beach-chair) or on your side. Usually you also get a nerve block, an injection near the neck that numbs the shoulder and eases pain after surgery.

How big are the incisions?

The surgeon works through small portals, typically 5-10mm incisions. There is no large open incision. A small portal at the back of the shoulder holds the camera, and one or two more at the front and side hold the working tools.

What exactly will be done inside my shoulder?

It depends on the problem. It may be a rotator cuff repair or a labral repair, making more room under the shoulder's bony roof, moving the biceps tendon to a new anchor point, or freeing scarred capsule for frozen shoulder. Sometimes the goal is simply to look inside when imaging has not given a clear answer.

Is arthroscopy always better than open surgery?

Compared to open surgery, the scope disturbs less tissue, causes less pain afterward, and shows the whole joint better. The trade-off is that some problems are still better fixed through an open incision, and the surgeon makes that call based on what is wrong.

Will I wear a sling afterward?

Yes. At the end of the procedure the portals are closed with stitches or adhesive strips, and a sling is applied.

What are the main risks?

Infection, bleeding, nerve injury (above all the axillary nerve, which wraps around the upper arm bone), stiffness, failure of the repair to heal to bone, and anesthesia-related risks. We offer the procedure because the condition, left untreated, typically worsens over time.
