Six cases of acute isolated posterior cruciated ligament (PCL) injuries were treated nonoperatively. They were mobilized with a functional knee brace at 3 weeks after immobilization in full extension.Magnetic resonance imaging and posterior stress radiography were performed at the time of injury and 6 months later. On the posterior stress radiographs at follow-up, all patients showed increasing stability compared to the time of injury (rangel-7mm). In all patients, the MR images of PCL had demonstrated a high intensity area on midsubstance at the time of injury, and this had decreased in intensity over the following 6 months. One case decreased in intensity to become like intact PCL, three cases decreased moderately and two cases only slightly decreased in intensity.This study suggested that the acute isolated PCL injury may acquire static stability without surgery.
