Achilles Allograft Reconstruction With V-Y Quadriceps Advancement for Chronic Patellar Tendon Insufficiency.

ABSTRACT:

Background

Chronic patellar tendon insufficiency often results in loss of active knee extension, retraction of the quadriceps, and patella alta. This study outlines a surgical technique for patellar tendon reconstruction using an Achilles allograft with V-Y quadriceps advancement, in the context of failed prior mid-substance patellar tendon repair.

Indications

Reconstruction is indicated in patients with complete tears of the patellar tendon that are non-amenable to primary repair. Other considerations include failed prior repair or persistent functional deficits in patients with contributing patellar tendon insufficiency. V-Y quadriceps advancement may be implemented if there are concerns for quadriceps retraction, patella alta, and inability to achieve tension-free reconst
