The medial collateral ligament (MCL) on the inner side of the knee is most often torn when there is a force that strikes the outside of the knee. The MCL attempts to resist widening of the joint and tears if the force is too great. When this happens, you face a recovery time of weeks to months, depending on the grade of the MCL tear.

A dislocation of the kneecap occurs when the patella comes completely out of its groove on the end of the thigh bone (femur), and comes to rest on the outside of the knee joint. Kneecap dislocations usually occur as a significant injury the first time the injury occurs, but the kneecap may dislocate much more easily thereafter.

The surgery can effectively provide pain relief and restore function, but the timeliness of the procedure is critical: Patients with knee osteoarthritis (OA) who keep putting off surgery may end up with so much joint degeneration that they do not experience significant improvement when they finally undergo TKA, while those who have the procedure prematurely may see only minimal benefit.

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.
