The anatomic double-bundle technique replicates the native shape of the medial patellofemoral ligament (MPFL), provides stability in both flexion and extension, and effectively limits rotation throughout ROM, helping minimize postoperative instability. The technique, if accomplished directly and anatomically, can also provide for more aggressive rehabilitation protocols and earlier return to activity.1
Tibial Tubercle Osteotomy
The Arthrex T3 AMZ system was designed to facilitate tibial tubercle osteotomy and transfer in a reproducible manner for extensor mechanism realignment and patellar unloading. The instrument set and disposables kit consist of 3 cutting guide arms, (45˚, 60˚ and 90˚) that rigidly connect to the tubercle pin and cutting block post placing the cutting block at specific angles on the tibial tubercle according to the most common cut angles needed.
