Bursitis is the painful swelling of bursae. Bursae are fluid-filled sacs that cushion your tendons, ligaments, and muscles. When they work normally, bursae help the tendons, ligaments, and muscles glide smoothly over bone. But when the bursae are swollen, the area around them becomes very tender and painful. Trochanteric bursitis is swelling affecting the bursae of the hip.
Hip bursitis is a common problem that causes pain over the outside of the upper thigh and hip joint. A bursa is a fluid-filled sac that allows smooth motion between two surfaces.
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.
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.
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.
