Abstract

Injuries to the posterior cruciate ligament (PCL) affect between 3-37% of ligament injuries in the population and there is still controversy regarding the diagnosis, classification, treatment and rehabilitation of this injury. The role of clinical judgment in quantifying posterior laxity is still limited, especially when there is concomitant injury of peripheral structures. The incomplete bicruciate injury refers to the complete rupture of the anterior cruciate ligament (ACL) and partial PCL injury. The partial lesion of the PCL (<50% of the substance) in combination with an ACL injury has not been evaluated in depth. MRI does not detect precisely the extent of the injury and there is no specific clinical test to detect the incomplete bicruciate injury, and therefore there are no biomechanical studies that assess posterior tibial translation in this type of injury.To better assess this injury biomechanically, we propose an in vitro laboratory study, using human cadaver knees. This study will be conducted in a laboratory of orthopedic biomechanics in Los Angeles - United States through an international collaboration. The knees will undergo a sequence of ligament injuries (ACL and PCL) and subsequent reconstructions of these structures and biomechanical evaluations. The outcomes that will be analyzed are: anteroposterior displacement of the tibia relative to the femur in varus-valgus instability and instability in external rotation, and internal rotation. (AU)
