Hand & wrist treatment
Wrist arthroscopy is keyhole surgery inside the wrist joint — a fine camera through openings a few millimetres across, giving a magnified view of structures no scan sees clearly. It is unusual among operations in that it does two jobs at once: it establishes what is wrong, and it treats what it finds in the same sitting. That matters because the wrist is a crowded joint of eight small bones, short ligaments and a cartilage complex, where subtle tears are genuinely hard to see on imaging. For a wrist that has hurt for months with inconclusive scans, this is often the operation that finally answers the question.
Two or three small portals are made over the back of the wrist. Through one, the arthroscope lights the joint and magnifies it onto a screen; through the others, fine instruments probe, trim, stitch and remove. The magnification matters in a joint this size — structures a few millimetres across are seen far more clearly than on any scan. Just as importantly, the joint can be probed and stressed while being watched, so a ligament that looks intact but has gone slack reveals itself. What follows depends on what is found: a frayed cartilage edge tidied, a rim tear stitched, a loose fragment removed, a ligament assessed and repaired. The keyholes ease the early recovery, but anything repaired inside heals on its own timetable.
Recovery after wrist arthroscopy — with a repair
These milestones describe an arthroscopy that included a repair — the repair, not the keyholes, sets the pace. A diagnostic look with a tidy-up is considerably quicker: early movement, light use within a couple of weeks, and most activities back by about six.

Most people arrive with one question louder than the rest. Tap yours — the straight answer is one scroll away.
For mechanical problems inside the joint, it is the most reliable way to both. This is what wrist arthroscopy is for: a torn cartilage complex on the little-finger side, a ligament between the wrist bones that has torn or gone slack, a loose fragment catching in the joint, inflamed lining, a ganglion arising from inside. These are precisely the things that scans struggle with and that arthroscopy sees clearly — and most of them can be treated during the same procedure. For a wrist that has hurt for months without a clear answer, that combination is what makes the operation worth doing.
What it will not do is fix a worn-out joint. Where the cartilage across the wrist has genuinely worn away, tidying inside does not relieve that pain, and arthroscopy in an established arthritic wrist tends to disappoint. That is a different problem with different answers. And occasionally the joint is found to be sound — which is not a failure but a real result: it rules out a whole set of causes and redirects attention to the tendons, the nerves, or how the wrist is being loaded. That possibility is discussed before you consent, not afterwards.
Wrist arthroscopy is well established and serious complications are uncommon, though it is technically demanding because the joint is small and the working space tight. The risks specific to the portals are worth naming: small sensory nerve branches and tendons run close to where the openings are made, so a numb or tender patch on the back of the wrist or hand can occur, and injury to a tendon is rare but recognised. Careful portal placement is what avoids both, and most numbness that does occur settles.
Beyond that, the general risks of joint surgery apply: infection, which is uncommon; swelling and stiffness while the joint settles; and the possibility that what is found requires more, or less, than was planned. Stiffness is worked against with early guided movement wherever a repair does not need protecting. All of this is weighed against the alternative — continuing with an unexplained, unresolved wrist — and discussed with you beforehand.
This is the question with two answers, because it depends on what happens inside. A diagnostic arthroscopy with a tidy-up allows early movement, light use within a couple of weeks and most activities back by about six. A stitched repair of the cartilage complex or a ligament is protected in a splint or cast for around six weeks, then movement is rebuilt, then strength — with heavier loading and twisting sport often around four to six months. Where are you in this?
The case is usually strongest for a wrist that has not settled and has not been explained. Months of pain, clicking or a sense of instability despite splinting, hand therapy and inconclusive scans is exactly the situation arthroscopy answers. Before that point, non-surgical treatment deserves a fair trial — many wrists settle without ever needing a look inside.
Prepare for two possible recoveries, because which one applies is decided during surgery. Plan for day surgery, and ask what would happen in each scenario — a tidy-up means weeks, a repair means six weeks protected and months of rehabilitation. Arrange help accordingly, set your home up for one-handed weeks in case, and remove rings beforehand.
Follow the plan for what was actually found — it governs everything. Where nothing needed protecting, early movement and a graded return to loading restore the wrist quickly. Where something was repaired, respect the protected weeks first, then rebuild movement and strength through hand therapy. Keep the fingers, elbow and shoulder moving throughout either way.
It depends on what was treated and, importantly, on whether what caused it was addressed as well. A rim tear of the cartilage complex, stitched back where the blood supply is good, generally heals and stays healed. A ligament repair holds for most people, though a heavily loaded or twisting wrist asks more of it. Loose fragments removed do not come back.
The situation that most often recurs is a degenerative central tear that was tidied while the loading that caused it continued unchanged — particularly where the outer forearm bone sits slightly long and grinds against that side of the wrist. Tidying relieves symptoms, but if the pressure stays, the problem tends to return; addressing the loading itself is what makes the result last. That is judged before surgery rather than discovered afterwards, and it is why the assessment looks at how the forearm bones sit as well as at the tear itself.
Many wrists settle without a look inside. Arthroscopy earns its place in specific situations — check yours:
That is the picture wrist arthroscopy is genuinely for. The next step is a consultation rather than a consent form: reviewing what has been tried, what the imaging does and does not show, and how the forearm bones sit — because where a long forearm bone is driving a degenerative tear, addressing that as well is what makes the result last. You will know the possible findings and what each would mean before you decide.
Good news — a look inside probably is not your next step. A recent injury, or a wrist that has not yet had a proper trial of splinting and hand therapy, usually settles without surgery. And where the wrist is already established arthritic, arthroscopy is not the answer. An assessment sorts out which situation applies. More: wrist sprains
And remember: the consultation’s job is the right answer for your wrist — including “no operation.”
Tap each card to reveal the answer:
It is keyhole surgery inside the wrist joint. Through two or three openings a few millimetres across, a fine camera is passed into the joint and projects a magnified view onto a screen, while small instruments work through the other portals. The wrist is a crowded space — eight small bones held together by short ligaments, with a cartilage complex on the little-finger side — and arthroscopy is the only way to see those structures directly and move them to test how they behave. It is used both to establish what is wrong and, in the same sitting, to treat what is found.
Because scans have real limits in a joint this small. An X-ray shows bone but not ligaments or cartilage, and while an MRI shows a great deal, subtle tears of the small wrist ligaments and of the cartilage complex are genuinely difficult to see and are sometimes reported as normal when they are not. Arthroscopy also does something no scan can: it lets the joint be probed and stressed under direct vision, so a ligament that looks intact but has gone slack can be identified. That is why it is the reference standard for a wrist that has hurt for months without a clear explanation.
A good deal. The cartilage complex on the little-finger side can be repaired where the tear is at the rim, or its frayed edge tidied where it is central and degenerate. Torn or slack ligaments between the wrist bones can be assessed and, depending on what is found, repaired or reinforced. Loose fragments of cartilage or bone can be removed, inflamed lining cleared, and a ganglion arising inside the joint excised. Where a fracture runs into the joint surface, the camera can confirm the surface has been restored smoothly during fixation — something an X-ray alone cannot show.
It depends almost entirely on what was done inside, not on the keyholes. A diagnostic look with a tidy-up allows early movement and a return to light use within a couple of weeks, with most activities back within about six. A repair is a different matter: a stitched cartilage or ligament repair is protected in a splint or cast for around six weeks while it heals, followed by hand therapy to restore movement, then strength, with heavier loading and twisting sport often around four to six months. The small incisions ease the early recovery either way, but repaired tissue heals on its own timetable.
That is an uncommon outcome when the operation is well selected, but it is a genuinely useful result rather than a wasted one. Knowing that the ligaments are intact, the cartilage complex is sound and the joint surfaces are healthy rules out a whole set of problems and redirects attention elsewhere — to the tendons, the nerves, or the way the wrist is being loaded. For someone who has spent months with unexplained pain and inconclusive scans, a clear answer in either direction is worth having. It is discussed beforehand as one of the possible outcomes, so it is never a surprise.
