1. Rounded Sagittal Profile: Allows for greater range of motion and is more forgiving to the retinaculum by not over tensioning the soft tissues.

2. Deeper Swept-back Trochlear Groove: Designed to resist patella crepitus and clunk, enhancing patellar performance.

3. Extended Trochlear Groove: Lengthened to support the patella in deep flexion and provide support for the quadriceps tendon.

4. Wider Proximal Trochlear Groove: Widened to reduce constraining forces in extension. Provides a 6.5-degree valgus angulation to reduce patellar shear stresses.

This system accords with the biomechanics of the patellofemoral joint, including loosening of the femoral retinaculum and clinically proven circular patella tracking.
