Knee Arthroscopy

ACL reconstruction, meniscus repair and arthroscopic treatment of knee injuries.

Knee arthroscopy is keyhole surgery: a small camera and fine instruments are passed through incisions of about one centimetre to see inside the joint and treat the problem without a large open operation.

When is knee arthroscopy needed?

• Anterior or posterior cruciate ligament (ACL/PCL) tears with an unstable knee.
• Meniscus tears causing pain, swelling or a "locking" knee.
• Loose bodies inside the joint or inflamed joint lining (synovitis).
• Selected cartilage injuries.

How is it done?

The operation is usually done under spinal or general anaesthesia. The surgeon works while watching a screen to repair or reconstruct the injured structure. In ACL reconstruction, one of the patient's own tendons is used as the new ligament and fixed inside the bone.

Recovery

• Most patients walk on the same or the next day, with crutches when needed.
• A structured physiotherapy programme starts early to restore movement and strength.
• Returning to sport after ACL reconstruction usually takes several months of rehabilitation.

When to book a visit

If your knee gives way, swells after a sports injury, or hurts with difficulty bending or straightening it, an early examination and the right imaging help choose the best treatment.
