Osteochondral Fractures of the Knee in Children and Adolescents Treatment With Open Reduction and Osteosynthesis Using Biodegradable Pins

Summary Osteochondral fractures of the femoral condyle are not uncommon in late childhood and adolescence, especially in connection with acute, traumatic dislocation of the patella. When the fragment is large, an open reduction and osteosynthesis is recommended. The best current solution to the technical problem of securing a thin osteochondral fragment is the use of resorbable pins, because resorbable pins allow immediate limited postoperative joint motion. In addition, some weight bearing is possible and can be performed without causing damage to other articular surfaces and without a risk of the fragment redislocating. No removal of the implants after fracture healing is necessary. The advantages of using biodegradable pins outweigh the risk for serious complications.
