PURPOSE The present study reports a long-term follow-up of acute primary patellar dislocation in patients with open physes. The purpose of the study was to evaluate knee function and recurrence rates after surgical and nonsurgical treatment of patellar dislocation. METHODS A total of 51 patients, including 29 girls and 22 boys, who were 9-14 years of age at the time of injury, were retrospect...

Arthroscopic technique for lateral release is the most widely used procedure for the correction of recurrent dislocations of the patella. In the relevant literature, several complications of lateral release are described, but the spontaneous patellar tendon rupture has never been suggested as a possible complication of this surgical procedure. Patellar tendon rupture is a rather infrequent and ...

Patellofemoral disorders represent 20–40% of all knee problems and can be one of the most common complaints in sports related injuries. These disorders are a major cause of disability, particularly in females, and in extreme cases may contribute to termination of athlete’s career and could lead to degenerative arthritic changes of the knee joint. For these reasons, disorders and in particular p...

BACKGROUND Pigmented villonodular synovitis (PVNS) is a rare proliferative process in children that mostly affects the knee joint. CASE PRESENTATION The study follows the case of a 3-year-old boy presenting recurrent patellar dislocation and PVNS. Due to symptoms such as chronic arthritis, he had been taking prednisolone and methotrexate for 6 months before receiving a definitive diagnosis. A...

Chronic patellar dislocation is a rare condition where the patella remains dislocated throughout knee range of motion during flexion and extension. In adults, the delayed presentation of this condition is often due to symptoms caused by the onset of severe secondary osteoarthritis. To the authors' knowledge, all of the cases reported in the literature have been treated by patellofemoral or tota...
