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.
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. Kneecap dislocations usually occur as a significant injury the first time the injury occurs, but the kneecap may dislocate much more easily thereafter.
Steroid injections can quickly relieve inflammation in the joints, and the effects may last from several weeks to several months. I’ve seen a number of patients who got significant relief from steroid injections every three or four months. But, a new report of one medical center’s experience and a review of past research came to some concerning conclusions about joint injections for osteoarthritis of the hip or knee.
Determining the cause of a swollen knee can sometimes be challenging. It may an acute condition caused by a traumatic injury or a chronic one which has developed slowly over time.
