A knee arthroscopy is a surgical procedure during which the doctor will look inside the joint to evaluate damage and/or problems. Damages found during a knee arthroscopy can include cartilage tears, wearing or injury of cartilage cushioning and ligament tears.
To begin the surgery, you will be given a general, spinal or local anesthetic. The doctor will make a small incision on the knee to insert the arthroscope. If additional surgery is required, the doctor will do so at this time. This should take about 45 to 90 minutes.
Once you are home, you should pay particular attention to swelling, dressing care, bearing weight on your knee, exercises to strengthen your knee and complications. You should keep your leg elevated and apply ice to reduce the swelling. You should keep your incisions clean and dry, away from direct contact with water and especially avoid taking baths.
You can gradually put more weight on your leg once the pain subsides. Your doctor will tell you how you can exercise your knee and may involve a physical therapist in your care.
