Insall tested whether adding a tibial polyethylene spine and transverse femoral cam to the total condylar prosthesis, substituting for posterior cruciate ligament function, improves knee function and motion. Clinical series of 91 patients (118 knees) with the posterior stabilized condylar prosthesis followed 2 to 4 years, compared with a prior total condylar cohort using HSS knee score, range of motion and radiographs.
