Hybrid Treatment of Osteochondral Fracture of the Patella With Particulated Juvenile Cartilage and Fragment Fixation

Abstract

Acute patellar dislocation can result in osteochondral fracture of the patella, resulting in multiple osteochondral fragments, with only one fragment able to be fixated into the defect effectively. In these cases, we propose a hybrid procedure to repair the defect using the fixation of one of the osteochondral fragments and particulated juvenile articulate cartilage to fill the remaining defect in the patella. This technique maximizes the amount of native articular surface that we can preserve on the patella. The use of fragment fixation in combination with particulated juvenile articulate cartilage will help prevent further articular damage to the patella and reduce the risk of developing osteoarthritis in patients suffering from an osteochondral fracture as a result of acute patellar dislocation.
