Knee Disorders
Total Knee Replacement
A total knee replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material. The knee is a hinge joint which provides motion at the point where the thigh meets the lower leg. The thigh bone (or femur) abuts the large bone of the lower leg (tibia) at the knee joint. During a total knee replacement, the end of the femur bone is removed and replaced with a metal shell. The end of the lower leg bone (tibia) is also removed and replaced with a channeled plastic piece with a metal stem. Depending on the condition of the kneecap portion of the knee joint, a plastic “button” may also be added under the kneecap surface.
Arthroscopic Surgery
ACL Reconstruction
When you twist your knee or fall on it, you can tear a stabilizing ligament that connects your thighbone to the shinbone. An anterior cruciate ligament (ACL) unravels like a braided rope when it’s torn and does not heal on its own. Fortunately, reconstruction surgery can help many people recover their full function after an ACL tear.
Meniscal Surgery
An arthroscopic meniscal surgery is a procedure in which a surgeon uses an arthroscope and other tools to remove all or part of a damaged meniscus in the knee or, if possible, to repair a meniscus. A meniscus is a piece of rubbery tissue (fibrocartilage) between the bones of the knee joint. An arthroscope is a tube with a light at the end that projects an image of the inside of your knee onto a TV monitor. The arthroscope is about the diameter of a pencil.
Cartilage Surgery
An articular cartilage injury, or chondral injury, may occur as a result of a pivot or twist on a bent knee, similar to the motion that can cause a meniscus tear. Damage may also be the result of a direct blow to the knee. Chondral injuries may accompany an injury to a ligament, such as the anterior cruciate ligament. Small pieces of the articular cartilage can actually break off and float around in the knee as loose bodies, causing locking, catching, and/or swelling. More often, there is no clear history of a single injury.
