The actual in vivo tibiofemoral and patellofemoral kinematics of the posterior cruciate ligament (PCL)-reconstructed knee joint are unknown.
Hypothesis: Current single-bundle PCL reconstruction is unable to correct the abnormal tibiofemoral and patellofemoral kinematics caused by rupture of the ligament.
Study Design: Controlled laboratory study/case series; Level of evidence, 4.
Single-bundle PCL reconstruction was successful in restoring normal anteroposterior translation of the tibia, as well as the patellar flexion and shift. However, single-bundle PCL reconstruction was unable to achieve the same success in mediolateral translation of the tibia or in the patellar rotation and tilt.
Clinical Relevance: The persistent abnormal mediolateral translation of the tibia, as well as decreased patellar rotation and tilt, provide a possible explanation for the development of cartilage degeneration after reconstruction of an isolated PCL injury.
