Understanding Knee Arthroscopy
Knee arthroscopy is a keyhole (minimally invasive) operation that lets the surgeon look directly inside your knee using a pencil-thin camera called an arthroscope. Through two or three small incisions, a magnified live image is projected onto a screen, so every surface of the joint can be examined in fine detail.
Because the same small incisions allow miniature instruments into the joint, most problems found can be treated in the same sitting — trimming or repairing a torn meniscus, smoothing damaged cartilage, or removing loose fragments. Compared with open surgery it means far less tissue damage, less pain, a lower infection risk and a much quicker return to normal life.
Key benefits
- Only two or three keyhole incisions instead of a large cut
- Less post-operative pain and a lower risk of infection
- Usually a day-care procedure — home the same day
- Faster return to work, driving and daily activities
When Knee Arthroscopy is recommended
How the procedure is performed
Anaesthesia & access
Under spinal or general anaesthesia, two to three keyhole incisions are made and sterile fluid gently expands the joint for a clear view.
Inspection
The arthroscope transmits a magnified image, letting Dr. Saxena systematically examine the cartilage, meniscus and ligaments.
Treatment
Using fine instruments, the torn meniscus is repaired or trimmed, rough cartilage is smoothed, and any loose fragments are removed.
Wash-out & closure
The joint is washed out, the fluid drained, and the tiny incisions closed with a stitch or adhesive strips and a light dressing.
Preparation & prerequisites
- A detailed clinical assessment and review of your scans (X-ray / MRI) to confirm the diagnosis and plan the surgery precisely.
- Routine pre-operative blood tests, an ECG if needed, and a fitness-for-anaesthesia check by the anaesthetist.
- Stopping blood-thinning medication (such as aspirin or clopidogrel) only if advised, and disclosing every medicine and supplement you take.
- Fasting for around 6 hours before surgery, and arranging a responsible adult to drive you home and stay with you the first night.
- Preparing your home for recovery — ice packs, loose clothing, and a clear path free of trip hazards.
What recovery looks like
Days 1–3
Rest, ice and elevate the leg. You'll walk with support the same day and be shown gentle movement and quadriceps exercises.
Weeks 1–2
Swelling settles, the dressing and stitches are checked, and guided physiotherapy begins to restore movement and strength.
Weeks 3–6
Most people return to desk work within days and to more active work and daily activities over a few weeks; sport follows once strength returns.
How to recover well
- Follow the RICE principle early — rest, ice 15–20 minutes several times a day, gentle compression and elevation to control swelling.
- Take pain relief as prescribed rather than waiting for pain to build, and keep the wound clean and dry.
- Attend every physiotherapy session and do your home exercises — rehabilitation is as important as the surgery itself.
- Progress activity gradually and don't return to sport until you're formally cleared, to protect the repair.
- Watch for warning signs — spreading redness, fever, calf pain or increasing swelling — and call us if they appear.
Risks, safety & outcomes
In experienced hands this is a very safe procedure, and serious problems are uncommon. Every step is taken to minimise risk — but being fully informed is part of good care. Possible risks include:
- Swelling, bruising or temporary stiffness that settles with rehabilitation
- Infection (uncommon) — treated promptly with antibiotics
- A blood clot in the leg (rare), which is why early movement is encouraged
- Occasionally, symptoms persist if the joint damage is more advanced than expected
Results & outlook
The great majority of patients get reliable relief of mechanical symptoms such as catching and locking, and return to their normal activities within a few weeks. When a meniscus is preserved rather than removed, the knee is also better protected against future arthritis.
Frequently asked questions
Most patients are pleasantly surprised. Discomfort is usually mild and well controlled with simple pain relief, and settles far faster than after open surgery.
