ABSTRACT

A posterior cruciate ligament (PCL) avulsion fracture is an uncommon injury with the general consensus towards operative fixation and of late, arthroscopic tight-rope fixation has gain attention with several case reports on its efficacy and good outcome. Our patient is a young gentleman who sustained a PCL avulsion fracture following a motor-vehicle accident. We subsequently proceeded with arthroscopic tight-rope fixation of the avulsion fracture. We were able to achieve a stable fixation under direct visualization and x-rays were acceptable. At 3 months post-surgery, his knee function is good with Tegner-Lysholm score of 84 (good). Fixation for PCL avulsion fracture through an arthroscopic approach is favourable due to smaller wounds and the ability to address possible concomitant injury however, it is technically demanding. A tight-rope fixation was recently described due to its increasing popularity and in most of the case reports including ours, a good outcome is achievable.
