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.
Use of decision aids developed for shared decision-making does not appear to reduce the odds of hip and knee arthroplasty in patients with osteoarthritis, according to a study published in the January issue of Health Affairs.
Rehabilitation after knee replacement is an essential part of the recovery process. But what's the best way to prepare patients before the procedure?
The quadriceps tendon is a thick, strong tendon that can withstand tremendous force. In daily life, it acts as part of the extensor mechanism to straighten the knee. People who injure the extensor mechanism may tear the quad tendon, tear the patellar tendon, or fracture the kneecap. All of these injuries have similar treatments and rehabilitation plans.
