Evaluation of the clinical results of posterior cruciate ligament reconstruction -a comparison between the use of the bone tendon bone and semitendinosus and gracilis tendons-

Introduction The techniques for reconstruction of the posterior cruciate ligament (PCL) are still being developed. There are some options when choosing a graft for PCL reconstruction. The bone tendon bone (BTB) and semitendinosus and gracilis tendons (STG) are widely used, but both have advantages and disadvantages. Each result after ligament reconstruction has been reviewed. However, few studies, in which the same surgeon has conducted the same rehabilitation program using the same bone tunnel, have compared postoperative results between BTB and STG. It remains to be clarified whether the results differ according to graft materials and their fixation between the two techniques [1-5]. We performed anterolateral single bundle reconstruction of the PCL using BTB and STG in a total of 30 cases, and the courses of the patients were observed for over one year. The postoperative results of PCL reconstruction using BTB and STG were compared and studied retrospectively. The purpose of the present study was to clarify the features of the two surgical methods and to explore the problems associated with these procedures and measures that could be used to improve them.
