Posterior Cruciate Ligament Graft Fixation Angles, Part I
Currently, no consensus exists for the optimal graft fixation angle for anatomic single-bundle (SB) posterior cruciate ligament reconstructions (PCLRs). Additionally, direct graft forces have not been measured. Alternative graft fixation angles and the resultant graft forces should be investigated to optimize the stability of SB PCLRs without overconstraining the knee. The results of this study suggest that SB PCL graft fixation angles of 75°, 90°, and 105° were comparable in restoring knee kinematics and exposed the graft to similar time-zero loads. However, SB PCLRs did not fully reduce knee laxity to the intact state.

Robert LaPrade, MD, PhD
has specialized skills and expertise in diagnosing and treating complicated knee injuries. He has treated athletes at all levels, including Olympic, professional and intercollegiate athletes, and has returned numerous athletes back to full participation after surgeries. Recognized globally for his outstanding and efficient surgical skills and dedication to sports medicine, he has received many research awards, including the OREF Clinic Research Award considered by many a Nobel Prize in orthopedics. Dr. LaPrade is one of the most published investigators
in his field, and many of the surgeries that he has developed are now performed worldwide and recognized as the “gold standard” for the treatment of complex knee injuries.
