Surgical treatment of acute and chronic anterior and posterior cruciate ligament and medial-side injuries of the knee.

KD-IIIM knee injuries are challenging injuries that can do well when anatomic reconstruction techniques are used. This article describes the authors preferred reconstructions, timing of surgery, and rehabilitation techniques. The reconstructions are generally initiated 3 or 4 weeks after the injury when the local soft tissue injury allows and associated fractures have already been stabilized. The posterior cruciate ligament, posteromedial corner, and meniscus injuries are addressed in the initial operation. The corresponding author prefers to come back 6 weeks later and reconstruct the anterior cruciate ligament and assure that acceptable progress has been made regarding knee motion.
