Knee arthroscopy is a minimally invasive surgical procedure used to diagnose and treat a range of knee injuries. The knee is the largest joint in the body comprising of the femur, tibia, and patella. The knee joint is lined with articular cartilage, which absorbs shock and provides a smooth surface for movement. It is surrounded by a capsule that contains synovial fluid, a lubricant that ensures smooth motion by reducing friction within the joint.
The knee is prone to injuries affecting the articular cartilage, ligaments, and other key structures that support its movement. Arthroscopy can be used to diagnose issues like a torn meniscus or a misaligned patella (kneecap). It can also be used to repair ligaments that may be torn or damaged, restoring function and alleviating pain within the joint. Knee arthroscopy is recommended when painful symptoms persist despite non-surgical treatments.
Through small incisions, surgeons insert a tiny camera to visualize the joint and perform treatments such as cartilage repair or ligament reconstruction. The advantage of arthroscopy is that it avoids the need for large cuts, reducing the trauma to surrounding soft tissues, speeding up recovery, and minimizing the risk complications as compared to traditional open surgery.
