Tibiofemoral and patellofemoral kinematics after reconstruction of an isolated posterior cruciate ligament injury: in vivo analysis during lunge.

ABSTRACT:

Background

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.

Methods

Seven patients with an isolated PCL injury in 1 knee and the contralateral side intact were included in the study. Magnetic resonance and dual fluoroscopic imaging techniques were used to compare the tibiofemoral and patellofemoral kinematics between the intact contralateral (control group), PCL-deficient, and PCL-reconstructed knee during physiologic loading with a si
