MPFL Reconstruction


The Arthrex Anatomic Double Bundle Technique for medial patellofemoral ligament (MPFL) reconstruction replicates the native shape of the MPFL and provides stability in both flexion and extension. The Double Bundle Technique also effectively limits rotation throughout the ROM, minimizing postoperative instability. The technique, if accomplished directly and anatomically, can also provide for more aggressive rehabilitation protocols and earlier return to activity.1

The MPFL Convenience Pack includes all disposables and implants needed to perform the technique including two 4.75 mm biocomposite SwiveLock® anchors, a 6 mm biocomposite Interference Screw and the appropriate reamers and guide pins.

The new MPFL Convenience Pack with TightRope® fixation system includes disposables and implants needed including two 3.5 mm biocomposite SwiveLock anchors and a TightRope system for femoral fixation, along with the appropriate reamers and guide pins.

Successful MPFL reconstruction is dependent on anatomic placement of the graft. Our technique incorporates the use of a femoral template to ensure proper placement of the graft in the femur. This position provides a static fixation point that equalizes the tension across the graft in flexion and extension, thus minimizing the stresses across the patellofemoral joint.
