Shoulder treatment
Shoulder arthroscopy is keyhole surgery for the inside of the shoulder — a way to repair and clear what is torn, pinched or loose through incisions the width of a pencil. The shoulder is one of the joints this approach suits best: through two or three small openings, a surgeon can reattach a torn rotator cuff, repair a torn labrum, stabilise a shoulder that keeps dislocating, and make room under the bony roof — all without laying the joint open. It has become the standard route for many shoulder operations because it spares the surrounding tissue. Like any operation, it is worth being just as clear about what it cannot fix as what it can.
Two or three keyholes are made around the shoulder. Through one, the arthroscope lights the joint and projects it magnified onto a screen; through the others, fine instruments repair, reattach, trim and smooth. Because the shoulder is a joint of wide movement rather than tight weight-bearing, the camera reaches most of what needs treating, and a great deal that once required opening the shoulder is now done this way. The keyhole approach means less disruption to the surrounding muscle and a gentler early recovery than open surgery — though the true timeline answers to what was repaired inside, not to the size of the skin incisions. Where a tendon or labrum was reattached, it heals to bone on its own biological schedule.
Recovery after shoulder arthroscopy — with a rotator cuff or labral repair
These milestones are for an arthroscopy that included a rotator cuff or labral repair — the repair, not the keyholes, sets the pace. A simple decompression or clean-up with nothing to protect is much quicker, allowing gentle movement early and desk work within a week or two.
Timings describe typical recoveries — what was treated inside decides your own, and our specialist will set that out before you commit.
Most people arrive with one question louder than the rest. Tap yours — the straight answer is one scroll away.
For the right problem, this is one of the more reliably effective operations there is — and the range it covers is wide. Structural problems inside a joint whose surfaces are otherwise sound: yes. A torn rotator cuff can be reattached to bone. A torn labrum can be repaired, restoring the socket’s depth. A shoulder that keeps dislocating can be stabilised. Bone and inflamed tissue pinching under the bony roof can be cleared. A stubborn frozen shoulder’s tightened capsule can be released, and a calcium deposit or loose fragment removed. For a shoulder held back by a specific, identifiable problem, fixing it through keyholes often restores function that rehabilitation alone could not.
Worn-out arthritis: no. Once the cartilage across the ball-and-socket joint has worn through, cleaning up inside does not relieve the pain, and arthroscopy in a broadly arthritic shoulder tends to disappoint. That shoulder is a different problem — managed first without surgery, and, where it comes to an operation, with shoulder replacement rather than a keyhole clean-up. Being honest about which shoulder is which is the whole point of the assessment.
Shoulder arthroscopy is a well-established operation, and serious complications are uncommon. The one worth naming for the shoulder specifically is stiffness: the shoulder is more prone than most joints to tightening up after surgery, which is exactly why the rehabilitation programme that follows is treated as part of the operation, not an afterthought. A shoulder rested too long or rehabilitated too little can end up stiffer than it started — an avoidable outcome with the right aftercare.
Beyond that, the risks are those of any joint surgery: infection, clots, and ongoing pain or swelling. Small nerves run near some of the keyhole sites, so a patch of numbness can occur and usually settles. And where a tendon or labrum was repaired, there is a chance the repair does not fully heal — more likely if it is loaded too soon, which is the reason the protected early weeks matter. Every one of these is discussed against how likely it is in your particular shoulder before you decide.
This is the question where the shoulder surprises people, because the answer depends almost entirely on whether something was repaired. A clean-up or decompression with nothing to protect allows gentle movement early and desk work within a week or two. A rotator cuff or labral repair is a longer road: the arm is protected in a sling for several weeks while the repair heals to bone, then movement is rebuilt, then strength — with a return to overhead sport often around four to six months. The keyholes are small either way; the repair inside sets the pace. Where are you in this?
The decision turns on two things: what the imaging shows, and how much rehabilitation you have genuinely done. Many shoulder problems settle with a proper strengthening programme, which deserves a fair trial first. Where a clear structural problem persists — a real cuff tear, a labral tear, recurrent instability — keyhole surgery has a strong case, and the sooner some tears are fixed the better they do.
Arrive well prepared. Keeping the shoulder as mobile and strong as comfort allows beforehand makes recovery smoother. Plan for day surgery, arrange the sling and set up your home for one-armed weeks if a repair is planned, and line up help for the early days. Knowing your rehabilitation timeline in advance takes the surprise out of a long recovery.
Recovery is a staged programme, not just a wait — and with the shoulder, the rehabilitation is where the result is won. Protect the repair, restore movement, then rebuild strength, each stage cleared before the next. The shoulder can stiffen if the programme lapses, so steady, guided progress is what turns a repaired shoulder into a dependable one.
It can, and the reasons are worth naming honestly. A repaired rotator cuff can re-tear, particularly a large tear in an older, worn tendon, or one loaded too hard too soon. A stabilised shoulder can dislocate again, more likely in a young athlete returning to collision sport or where there was significant bone loss. And where arthroscopy cleaned up a joint whose cartilage was already thinning, the underlying wear continues regardless — the operation treated what was torn or catching, not the passage of time in the joint.
What most reliably protects the result is respecting the repair while it heals and completing the rehabilitation rather than stopping once the shoulder feels better. Returning to heavy overhead loading or contact sport before the tissue is ready is the commonest reason a good repair fails. Where the risk of recurrence is high from the outset — a very large tear, major instability with bone loss — that is discussed before surgery, because it sometimes points to a larger operation than a keyhole repair.
Many shoulders do not, and a fair trial of proper rehabilitation comes first for almost everyone. Shoulder arthroscopy earns its place in specific situations — check yours:
That is the picture shoulder arthroscopy is genuinely for. The next step is a consultation rather than a consent form: confirming what is torn or catching on imaging and the state of the joint’s cartilage — because that last one decides whether this operation helps or merely delays a better one. Some tears also do better repaired sooner rather than later.
Good news — keyhole shoulder surgery probably isn’t your answer yet. Many shoulder problems — impingement, tendinopathy, many partial tears — settle with a proper strengthening programme, and a worn-out arthritic joint needs a different operation altogether. An assessment builds that plan and keeps watch for the exceptions.
And remember: the consultation’s job is the right answer for your shoulder — including “no operation.”

Keyhole surgery to the shoulder joint. Through two or three small incisions, a camera — the arthroscope — lights the inside of the joint and projects it magnified onto a screen, while fine instruments passed through the other openings do the work. The shoulder is one of the joints arthroscopy suits best, and a great deal can be done this way: repairing a torn rotator cuff, reattaching a torn labrum, tightening an unstable shoulder, making more room under the bony roof, and clearing inflamed tissue or loose fragments. It has become the standard approach for many shoulder operations because it spares the surrounding tissue that open surgery would have to divide.
A wide range. The common ones are rotator cuff tears (reattaching the torn tendon to bone), labral and SLAP tears (repairing the socket’s cartilage rim), shoulder instability (stabilising a shoulder that keeps dislocating by repairing the torn labrum and tightening the joint), and impingement (removing bone or inflamed tissue pinching under the bony roof). It is also used to release a stubborn frozen shoulder’s tightened capsule, clear a calcium deposit, and remove loose fragments. What it does not treat is advanced, widespread arthritis of the ball-and-socket joint, which usually needs replacement rather than a keyhole clean-up.
It depends heavily on what was done inside, and the shoulder is unusual in that the recovery is often governed by protecting a repair rather than by the small incisions. A simple decompression or clean-up allows early gentle movement and a return to desk work within a week or two. But a rotator cuff or labral repair needs the arm protected in a sling for several weeks while the repair heals to bone, followed by months of staged rehabilitation — with a return to overhead sport often around four to six months. The keyhole approach eases the early recovery, but a repaired tendon or labrum still heals on its own biological timeline.
It is a well-established, low-risk operation in experienced hands. The risks are those of any joint surgery: infection, clots, ongoing pain or stiffness, and occasionally the need for further surgery. Stiffness afterwards is the one worth naming for the shoulder specifically — the shoulder is prone to stiffening, so the rehabilitation that follows matters as much as the operation. Small nerves run near some of the keyhole sites, so a patch of numbness can occur and usually settles. Where a repair was done, there is also a chance it does not fully heal, particularly if loaded too soon — which is why the protected recovery is taken seriously.
For most problems inside the shoulder — cuff tears, labral tears, instability, impingement — keyhole surgery is now the usual route, with less disruption and a smoother early recovery than opening the shoulder. Some situations still call for open surgery or a larger operation: very large or complex cuff tears, major bone loss in a repeatedly dislocating shoulder, and a joint worn out by arthritis, which needs replacement rather than arthroscopy. Often the assessment under arthroscopy guides the plan — the surgeon confirms what is torn and repairs it in the same sitting. The consultation and imaging beforehand sort out which your shoulder needs.
