Knee arthroscopy is a less invasive surgical procedure used to diagnose and treat knee injuries. During the procedure, small incisions are made and a tiny camera is inserted to examine the inside of the knee joint. Knee arthroscopy allows surgeons to diagnose issues like torn cartilage and ligaments, and in some cases perform repairs. It is quicker than other knee surgeries, taking less than an hour, and has benefits like less post-operative pain and lower risk of infection compared to more invasive options.
