Abstract
T functional disability. Eight displaced avulsion injuries were treated by open reduction. In four knees the fragment was sutured back to its origin on the posterior superior aspect of the tibia, and three of the these united. In two knees the fragment was large enough to fix with a screw and union ensued. There was excellent functional capacity in five of the six that united. The other two displaced fractures, treated three and seven months after injury, had open reduction and the fragments were sutured to the tibia in an advanced position. Union was obtained in both with good functional capacity. Of fourteen isolated avulsion fracutres of the posterior tibial attachment of the posterior cruciate ligament, one was undisplaced and five were minimally displaced. These six were treated conservatively, but four of the five displaced avulsion fractures progressed to non-union and significant functional disability. Eight displaced avulsion injuries were treated by open reduction. In four knees the fragment was sutured back to its origin on the posterior superior aspect of the tibia, and three of the these united. In two knees the fragment was large enough to fix with a screw and union ensued. There was excellent functional capacity in five of the six that united. The other two displaced fractures, treated three and seven months after injury, had open reduction and the fragments were sutured to the tibia in an advanced position. Union was obtained in both with good functional capacity. Copyright © 1975 by The Journal of Bone and Joint Surgery, Incorporated...
