Hip and Knee Services
The hip and knee joints are found at the opposite ends of the body’s largest bone, the thigh bone or femur. The hip joint, a ball and socket joint that allows movement in a number of directions, is formed by the ball at the top of the femur and the socket, which is part of the pelvic bone. The knee joint, a hinge joint that allows movement in only one plane, is formed between the lower end of the femur and the upper end of the tibia or shin bone. The surface of each bone at the level of the joint is covered by a layer of smooth cartilage which allows an undamaged joint to move smoothly with little friction. In the knee there is an additional kind of cartilage called meniscus that is a rubbery cartilage that serves as an actual cushion between the bone ends. Ligaments, thick bands of tissue around the joints, support the joints and prohibit excessive movements, such as a knee moving side-to-side instead of just up and down. Tendons are the parts of muscles that attach to bones adjacent to joints and it is the muscles that make a joint move.
Considering the complex anatomy of joints it’s no wonder that a wide variety of maladies can effect them. Tendonitis, such as jumper’s knee, is inflammation of a tendon and is generally the result of chronic overuse. Tendonitis usually responds to treatment by some combination of rest, medication or therapy. A strain is an injury to a tendon that is overstressed in a single injury and can include such force that the tendon is actually torn completely requiring surgical repair. Sprains are injuries to ligaments that are stretched beyond their limits and can vary in severity from a mild stretch to a complete tear which may require surgery, such as a torn anterior cruciate ligament (ACL) in the knee. A torn meniscus in the knee is usually treated by arthroscopic surgery. Wearing of the cartilage surfaces in joints is called arthritis. Mild cases may respond to activity modification, medication, bracing or injections while more severe cases may necessitate joint replacement.
