Type III tibial avulsion fracture with associated anterior cruciate ligament injury: Report of two cases in adults.

Tibial spine avulsion fractures are more common in children than adults. Many reports have provided classification and treatment options, including fixation for displaced type III fractures. However, long-term follow-up on injury to the anterior cruciate ligament and knee joint stability in adults is not well documented. We present 2 cases of type III tibial avulsion fractures in adults with associated interstitial injury to the anterior cruciate ligament. Primary anterior cruciate ligament reconstruction was performed in both patients.
