Abstract

The approach to the posterior cruciate deficient knee is controversial The purpose of this study is to document the biomechanical changes in the static cadaveric knee model with simulated physiological loads Nine fresh cadaveric knees from young donors aged under 45 years were mounted on a materials testing machine Loading was carried out at 0° 30° and 60° to 15 kN with lowpressure sensitive Prescale film Fuji Tokyo Japan inserted through arthrotomies into the medial and lateral compartments Computerized analysis of the imprints on the film was then carried out Tests were then repeated after cutting the posterior cruciate ligament PCL Results demonstrate a statistically significant posterior subluxation of the tibia on the femur at 60° flexion This causes a significant increase in contact pressure and pressure concentration on the medial compartment of the knee after cutting the PCL This may help explain the longterm degenerative changes observed in the medial femoral condyle after cutting the PCL
