Injuries of knee generally result in damage to major ligaments which stabilize this joint. Clendenin observed that 20% failure of ligaments of knee it is PCL rapture. A consequence of this type injuries is mechanical and functional instability of the knee joint. The goal of this article is to present our technique of arthroscopic reconstruction of PCL. We also present preliminary results of our treatment options we have applied in 14 surgery patients. The study material consisted of 14 patients who underwent surgical treatment for PCL injuries in the Department of Pediatric Orthopedics and Traumatology in Poznań. The arthroscopic reconstructions of PCL in all 14 patients have been performed by first author with the same operative technique. Knee laxity we assessed before and after PCL reconstructive surgery using arthrometer "Rolimeter" (Aircast). Knee ligament rating scales (Lyscholm and IKDC 2000) have been used to perform subjective, functional assessment of knee joint. The follow up was about 2 years. We fund statistical important improvement in all tested data (p = 0.001). The arthroscopic reconstruction of PCL with autogenic hamstring graft improves function and stability of knee joint. Endurance and size of hamstring grafts are sufficient to restore good mechanical and functional stability of knee joint.
