Sports Injuries & Arthroscopy
Arthroscopy lets a joint be diagnosed and treated through incisions the width of a pencil, using a camera and fine instruments rather than opening the joint. For sports injuries this matters enormously: less disruption to healthy tissue means less pain, a shorter stay, and a faster, more predictable return to activity. The operation is only half the result, though — what happens in the months of rehabilitation afterwards determines the other half.

What is arthroscopy (keyhole surgery)?
A small camera is introduced into the joint through one incision, and instruments through one or two others. The surgeon works from a magnified view on screen, which shows the joint surfaces, ligaments and cartilage in more detail than an open approach would. Because the surrounding tissue is left largely undisturbed, most arthroscopic procedures are done as day-care or single-night stays. It is used most often in the knee and shoulder, and also in the ankle, hip and wrist.
ACL injuries: who actually needs reconstruction?
Not every ACL tear needs an operation, and the honest answer depends on your knee and your demands rather than on the scan alone. Physiotherapy can work well for lower-demand patients who do not play pivoting sports, whose knee is stable and who have no significant associated injuries. Reconstruction is generally recommended for athletes at any level, for people whose work is physically demanding, for anyone whose knee keeps giving way, and when a repairable meniscus tear accompanies the ACL. The reason not to simply wait and see is that every giving-way episode risks tearing a meniscus or damaging cartilage, and repeated instability is a well-established route to early arthritis.
Meniscus tears: repair or trim?
The menisci are the knee's shock absorbers, and preserving them protects the joint surface for decades. Wherever a tear is repairable, repair is preferred over removal — but repairability depends on the tear pattern, its location and its blood supply. The outer third of the meniscus has a blood supply and heals; the inner portion largely does not. Repair requires a longer, more protected rehabilitation than trimming does, which is a trade-off worth understanding before surgery rather than after. Removing meniscal tissue gives quicker early relief but increases long-term load on the cartilage.
Shoulder problems in sport
Two patterns dominate. Rotator cuff injuries produce pain on overhead activity, night pain when lying on the affected side, and weakness on lifting or rotating the arm — common in throwing and racquet sports, and increasingly with age. Shoulder instability follows a dislocation and shows up as recurrent slipping or apprehension in certain positions, particularly overhead and behind the body; younger patients who dislocate have a notably high rate of recurrence. Both are assessed clinically and with MRI, and both can often be addressed arthroscopically.
Why rehabilitation decides the result
A technically perfect reconstruction fails if the rehabilitation does not follow. After ACL reconstruction in particular, the graft is at its biologically weakest around months two to four — precisely when the knee starts to feel good. Returning to sport in that window is the commonest cause of re-tear. This is why return to pivoting sport should be a test-based decision, confirmed by strength and hop testing, rather than a date on a calendar. Rehabilitation is supervised in conjunction with your physiotherapist and progressed on evidence of readiness.
Returning to sport safely
- Week 0–2: protect the joint, restore full extension, reactivate the quadriceps
- Week 2–6: off crutches, stationary cycling, regain full range of movement
- Month 2–3: progressive strengthening; desk work comfortable
- Month 4–6: straight-line running and sport-specific drills
- Month 8–12: return to pivoting sport once strength and hop tests confirm readiness
Frequently Asked Questions
What is keyhole (arthroscopic) surgery?
Arthroscopy uses a small camera and fine instruments inserted through incisions a few millimetres wide, so the joint is treated without being opened. The surgeon works from a magnified view on screen. Because healthy tissue is largely undisturbed, most arthroscopic procedures are day-care or one-night stays with faster recovery than open surgery.
Does every ACL tear need surgery?
No. Lower-demand patients with a stable knee and no significant associated injuries often do well with structured physiotherapy. Reconstruction is usually recommended for athletes, physically demanding jobs, anyone whose knee gives way repeatedly, or when a repairable meniscus tear accompanies the ACL. Repeated giving-way is what damages the joint over time.
Is a meniscus tear repaired or removed?
Repair is preferred wherever the tear allows it, because preserving meniscal tissue protects the joint surface long term. Repairability depends on the tear pattern and location — the outer third has a blood supply and can heal, the inner portion largely cannot. Repair requires longer protected rehabilitation than trimming.
How soon can I return to sport after knee arthroscopy?
It depends entirely on what was done. A simple meniscal trim may allow return to sport within weeks, whereas ACL reconstruction takes 8–12 months before pivoting sport, and meniscal repair requires a longer protected phase. Return to sport should be confirmed by strength and hop testing rather than decided by elapsed time.
What happens if a sports injury is left untreated?
It depends on the injury, but instability is the pattern that causes lasting damage. A knee that repeatedly gives way progressively injures the menisci and cartilage, and recurrent shoulder dislocations progressively damage the socket rim and its labrum. Both make later surgery more complex and less predictable, which is why recurrent instability warrants assessment.
