Pain on the outer (or lateral) part of the knee can be caused by an injury. It may also be the result of inflammation in a band of tough fibrous tissue that runs down the outside of the thigh, and attaches to the front of the tibia (shin bone). Pain in this area may also be caused by arthritis.
Stay off the court: For overweight people with arthritic knees, racket sports like tennis and racquetball may accelerate degeneration of the joints, a new study finds.
Orthopaedic surgery techniques for treatment of recurrent shoulder instability are effective, but prone to problems with nonunion of bone grafts held in place by screws alone. A new technique—borrowing a design used for centuries in Chinese architecture and woodworking—provides an effective approach to shoulder stabilization, suggests a study in The Journal of Bone & Joint Surgery.
An elbow dislocation occurs when the upper arm and forearm get separated from their normal position. The bone of the upper arm (humerus) normally touches the bones of the forearm (the radius and ulna). When an elbow dislocation occurs, these bones are separated from their normal alignment. Elbow dislocations are the second most common joint dislocation, following shoulder dislocations.
