Tibial-sided anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) avulsion fractures compose a rare subset of cruciate ligament injuries. Fixation strategies are mixed in the literature, particularly regarding the PCL, which has traditionally been addressed using an open approach.
A 41-year-old male sustained avulsion fractures of the tibial eminence involving the ACL, PCL, and posterior medial meniscal root through an unknown mechanism while sleepwalking. Surgical treatment comprised of entirely arthroscopic reduction and transtibial suture fixation. Only seven cases of combined ACL/PCL avulsion fracture have been reported and all but one utilized open fixation for at least the PCL and restricted weight-bearing postoperatively.
This previously unreported triad of injury was successfully managed arthroscopically, negating a posterior approach to the knee. Early post-operative weight-bearing and aggressive range of motion aided in swift recovery and a favorable outcome.
