Knee Stability After Total Knee Replacement with the Biomet Prosthesis as Evaluated by Stress Radiography
Numerous types of total condylar knee prostheses are available. In recent years designs have emerged that allow preservation of the posterior cruciate ligament. At the Frederiksberg Hospital in Copenhagen we use the Biomet total condylar prosthesis, which differs from conventional ones in that the tibial component is contoured at its posterior aspect to allow retention of the posterior cruciate ligament. The aim of the present study was to investigate anterior, posterior, valgus and varus laxity in patients after replacement with this prosthesis.
