MQTFL reconstruction

Abstract

Deficiency of medial patellofemoral support structure may lead to recurrent lateral instability of the patella following a patellar dislocation, and therefore restoration of medial patella support is often necessary to reestablish permanent stable tracking of the patella. Most important in the process of achieving long-term patella stable function, however, is achieving balanced tracking initially before any retinacular reconstruction is undertaken. In patients with lateral tracking of the extensor mechanism, it is important to determine if medializing the extensor mechanism by tibial tubercle transfer is necessary for an optimal, stable result prior to medial reconstruction. In patients with a symptomatic articular lesion of the patella, anteriorization, anteromedialization, or articular resurfacing may be needed prior to medial patellofemoral reconstruction.
