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 ROM, helping to minimize postoperative instability. The technique, if accomplished directly and anatomically, can also provide for more aggressive rehabilitation protocols and earlier return to activity.1
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 helping minimize stress across the patellofemoral joint.
Arthrex offers 4 MPFL convenience packs to address each patient's unique needs as well as each surgeon's preference for fixation. The newest kits use 3.9 mm BioComposite SwiveLock® anchors for patellar fixation and either a 6 mm × 20 mm BioComposite FastThread™ interference screw or an ACL TightRope® implant for femoral fixation.
