Posterior condylar cam lesion is an impingement which limits hyperflexion and may be an early clinical finding prior to bearing dislocation and wear. The α-angle is a marker showing the severity of this cam lesion. This problem can be overcome using intraoperative fluoroscan views during cam excison and replacing the femoral component in 105° knee flexion.

The combination of arthroscopic subtotal synovectomy and radiosynoviorthesis can be an effective treatment modality for chronic non-specific synovitis of the knee.
