The knee cap, or patella, attaches from the quadriceps muscle and has a ligament attached into the tibia bone. When the knee bends, the patella glides downward; it moves upward when the knee straightens. Patella dislocation happens when the knee...
A patellar subluxation can put a crimp in your mileage if you are an avid runner. Unlike a kneecap dislocation, a patellar subluxation can cause shifts in the kneecap position that usually resolve themselves; however, they are uncomfortable and...
There are numerous causes of kneecap pain. The kneecap, or patella, along with the tibia and femur and numerous soft tissue structures, compose the knee joint. The patella protects the anterior or front aspect of the knee joint from injury....

Your kneecap, known as the "patella," connects your tibia (shinbone) to the muscles in the front of your thigh and fits into a femoral groove. When the kneecap moves out of this groove, a partial or complete dislocated patella occurs. A...
The University of Minnesota Sports Medicine Institute states that knee swelling is categorized as either intra-articular knee effusion, which is swelling inside the knee joint, or localized swelling around the knee joint. Determining the cause of...
Patellofemoral pain occurs in the front of the knee. Approximately one-third of knee pain is related to the patellofemoral joint, writes Jay Lieberman in the "AAOS Comprehensive Orthopaedic Review." A clinician is able to generally diagnose the...
Recurrent dislocation of the patella, or kneecap, occurs when the kneecap does not track properly through the corresponding groove in the femur, or thigh bone. Repeated occurrences of dislocation can cause significant damage to the cartilage joint...
Knee braces support the knee's ligaments by controlling certain movements and providing protection against abnormal or excessive knee movement on operative and non-operative injured knees. Knee braces come in various shapes and sizes and serve...
When you suffer a kneecap dislocation injury, the patella---a bone shaped like a triangle over the knee---shifts out of its usual position, usually toward the outside of the knee, according to the National Institutes of Health's MedlinePlus...
Children who play soccer are especially susceptible to knee pain and injuries. The knee, one of the largest, most complex joints of the body, potentially can twist into the wrong position with each kick of a soccer ball. If you suspect your young...
A patella injury is an injury to the kneecap or patella. Injuring your patella is often the result of a direct blow or fall on the knee. Direct impact injuries are often sports related, such as the result of a hockey stick or football cleat....
When your kneecap is unstable, it doesn't track properly within the groove on the femur, according to Cedars-Sinai Medical Center. The condition is referred to as kneecap, or patellar, dislocation or patellar sublimation. It may cause symptoms...
Patellar subluxation is a condition where the patella, or kneecap, slips out of the socket slightly and then right back in. The kneecap fits into a groove at the end of the femur. When subluxation occurs the kneecap slides out of this groove, most...
Knees support the body, enable mobility, and play a supporting role in prayers and marriage proposals. This hard-working hinge is a compound joint made up of two long bones, the femur and the tibia, and the flat shield-like patella, or kneecap,...
The knee is a hinge joint where the tibia and femur meet. The back of the kneecap and the ends of the tibia and femur are protected by articular cartilage. There are also pads of cartilage --- meniscus --- that form cushions that act as shock...
