摘要

Objective

Restoration of passive medial stability of the patella by reconstruction/augmentation of the medial patellofemoral ligament complex.

Indications

Treatment of first-time patellar dislocation requiring surgery and recurrent dislocation as an isolated procedure or in combination with concomitant osseous intervention.

Contraindications

Patellofemoral pain without objective instability/dislocation of the patella; known material intolerance.

Surgical technique

A synthetic ligament is inserted in a V-shaped fashion into the second layer of the medial retinaculum via a 2-incision technique after soft tissue fixation in the area of the patellar medial patellofemoral complex (MPFC) and fixed at the femoral insertion using an interference screw.

Postoperative management

Partial weight-bearing for 2–3 weeks as tolerated; active and passive exercises without restriction of range of motion; immediate exercises for quadriceps muscle control, and coordinative exercises as well as stabilization of the functional pelvis–leg axis after full weight-bearing is achieved.

Results

The clinical results in the literature consistently show significant improvements in the patient-reported outcome measures and are so far—along with the biomechanical data—comparable with those of autologous tendon reconstruction.
