Total Knee Replacement for Valgus Deformity

Total knee replacement was performed on three cases with severe valgus deformity. Kinematic Rotating Hinge was used for two cases that had ligamentous instability and loss of bone. Kinematic Stabilizer prosthesis was used for a case by releasing of lateral structure and reefing of medial stracture. We released the peroneal nerve for all the cases to prevent the peroneal palsy. The patella dislocation was treated by proximal realignment of the quadriceps, lateral retinacular release and advancing the medial flap.
