Edges of the proximal stump were freshened and the reducibility was checked on the patella in extension and 40  knee flexion (Fig. 1).
Post-repair, complete apposition of the quadriceps tendon and retinaculum on both sides.

Two free suture tapes were then passed from the medial patellofemoral retinaculum to the quadriceps tendon to the lateral patellofemoral retinaculum and tied to reinforce the fixation (Fig. 2).
At 8 weeks postoperatively, the patient can sit on the edge of the bed with 90  knee flexion.

At 8 weeks postoperatively, the patient developed 50  active knee bending and 90  knee bending while doing the edge of the bed sitting, and full extension with straight leg raising (Fig. 3, 4, 5).
At 8 weeks postoperatively, the patient has achieved 50  active knee bending in supine.
