Lateral patellofemoral ligament reconstruction to restore functional capacity in patients previously undergoing lateral retinacular release

Abstract

This novel technique for LPFL reconstruction is effective at restoring lateral restraint of the patellofemoral joint and improving joint functionality.

Medial Patellofemoral Ligament Reconstruction With Concomitant Lateral Patellofemoral Reconstruction for Patellar Instability

“…Beckert et al. 9 described yet another technique using a hamstring allograft with suspensory femoral fixation and sutured patellar fixation in 19 knees, showing no postoperative apprehension and improved Knee Injury and Osteoarthritis Outcome Score. Although these early results are promising, further research is needed to determine optimal techniques and evaluate long-term outcomes.…”

“…Sanchis-Alfonso et al 8 reported on 17 knees at 18 to 48 months postoperatively using ITB autograft and found similarly improved Lysholm scores and improved psychometrics postoperatively. Beckert et al 9 described yet another technique using a hamstring allograft with suspensory femoral fixation and sutured patellar fixation in 19 knees, showing no postoperative apprehension and improved Knee Injury and Osteoarthritis Outcome Score. Although these early results are promising, further research is needed to determine optimal techniques and evaluate long-term outcomes.…”

“…While a range of techniques have been described resulting in good outcomes, our preference is to perform a soft tissue–based LPFL reconstruction. 8 , 9 , 10 Due to the paucity of literature as well as the varied anatomical descriptions, for the purposes of discussion in this manuscript, the term LPFL reconstruction will refer to any augmentation technique of the lateral retinaculum to treat medial patellar instability.…”

Lateral Patellofemoral Ligament Reconstruction With a Gracilis Allograft

“…The graft is fixed at the femur with suspensory fixation, and the 2 limbs are sutured to the anterior aspect of the patella. 9 …”

“…Several methods of LPFL reconstruction have been described, with primary differences consisting of graft choice and patellar fixation. 5 , 6 , 7 , 8 , 9 …”
