Although the surgical reconstruction of the posterior cruciate ligament (PCL) at times can be controversial, there is a certain population of patients in which this is indicated. In previously described techniques, an open procedure is required. This procedure has the associated drawbacks of longer rehabilitation and increased surgical morbidity because of the arthrotomy incision. With the further refinement of arthroscopic techniques, the arthroscopically assisted PCL reconstruction using autologous patellar tendon graft has been refined to offer improved results compared with those of an open procedure. The indications for the surgery and the techniques of the surgical procedure of arthroscopic PCL reconstruction will be described.
