A gamekeeper's thumb, also called a skier's thumb, is an injury to one of the important ligaments at the base of the thumb joint. The injury involves the ulnar collateral ligament (UCL), a band of tough, fibrous tissue that connects the bones at the base of the thumb. This ligament prevents the thumb from pointing too far away from the hand.
Chondromalacia patellae is a term used to describe the damage or softening of the cartilage on the underside of the kneecap. It is similar to patellofemoral pain syndrome (runner's knee) in which the pain is felt under and around the kneecap. This condition is common among young athletics but may also occur in older adults who have arthritis of the knee.
