Knee arthroscopy is minimally-invasive ‘keyhole’ surgery that is used to diagnose and treat a wide range of knee problems. A high definition fibre-optic camera and small instruments are passed into your knee through two or three small (1cm) incisions. The structures within your knee are assessed including the condition of the joint surfaces (articular cartilage), the meniscal cartilages, cruciate ligaments and the synovium (lining of the knee).

Conditions that are commonly treated with arthroscopic surgery include meniscal tears, articular cartilage injuries, loose bodies and knee stiffness due to arthrofibrosis (fibrous bands that can restrict movement of the joint). Arthroscopy is also used to perform cruciate ligament surgery and assist treatment of unstable knee caps. It can also aid diagnosis, for example by taking synovial biopsies.

Surgery is usually performed under general anaesthesia and as a day case procedure, such that you can go home 2-4 hours after the operation. Sometimes, you may be required to stay overnight for medical reasons. Most patients will be able to weight-bear and walk as comfortable after surgery but this depends on the exact procedure performed. Certain operations may require you to be non-weight bearing or partial weight bearing with crutches for a period of time.
