BONE TUNNEL WIDENING AFTER ANTERIOR CRUCIATE LIGAMENT AUTOPLASTY WITH HAMSTRINGS (LITERATURE REVIEW)

Abstract

ABSTRACT Such a phenomenon as bone tunnel widening after anterior cruciate ligament autoplasty with hamstrings has been known for 30 years. Despite the long history of this issue, the etiology is still not fully understood. The process of expansion of the bone tunnels is influenced by many factors such as graft fixation technique, surgical technique and rehabilitation protocol, as well as various biological factors. It is believed that this phenomenon has no influence on a functional result, but may create serious problems in revision anterior cruciate ligament surgery. Given the growing interest in the use of hamstring tendon grafts for anterior cruciate ligament reconstruction, increasing number of these operations and as a result, of revision procedures, the search for methods of bone tunnel widening prevention is becoming more urgent.
