Product Description

                  


Features

1.Optimized patellofemoral articular surface: deeper, extended, swept-back, widertrochlear groove;

2.Extended cam and heighten Ps post;3. Maximized preservation of bone stock;4.Sizing;

3.Effective reduction of postoperative wear.

Advantages
1. Rounded Sagittal Profile
Two distinct femoral designs:Anatomic (box-like) femoral profile and swept-back (rounder) femoral profile.Rounded sagittal profile, as founded in the SK1 knee,allows for greater range of motion and may be more forgiving to the retinaculum by not over tensioning the soft tissues.

2. Deeperlswept-back Trochlear Groove
The trochlear groove is a critical design feature for patella performance. Translation of the trochlear groove posteriorly in the femur has shown to resist patella crepitus and clunk. The SK1 trochlear groove has been designed to sweep back posteriorly for better patellar performance.

3. Extended Trochlear Groove
The trochlear groove has been lengthened to further support the patella in deep flexion and provide more support of the quadriceps tendon.The junction of the trochlear groove and PS box articulates with the quadriceps tendon at 105-120 degrees of flexion.



4. Wider Proximal Trochlear Goove
Patellar capture during flexion must be balanced with the need for less patellar constraint in extension.The trochlear floor of the SK1 knee has been widened to reduce the constraining forces in extension. The patella track provides a 6.5 degree valgus angulation and a 2mm lateralized trochlear groove."Valgus angulation has been shown to reduce the patellar shear stresses."

Except the wider trochlear groove,SK1 knee system provides a set of plan to accords with the biomechanics of patello femoral joint,including loosening of femoral retinaculum, more lateral trochlear and clinically proven good effect circular patella. To sum up the above total features, the wider proximal trochlear groove offers excellent patellar tracking (within 0-15 degrees of valgus) regardless of the patient's Q-angle.The loosening of femoral retinaculum will decrease effectively the tensile force of soft tissue to reduce the potential need to the loosening of lateral accessory ligament.
