Modern synthetic material is a safe and effective alternative for medial patellofemoral ligament reconstruction

Purpose Medial patellofemoral ligament (MPFL) reconstruction is often performed using gracilis autografts, which may be associated with donor site morbidity and complications. The use of a synthetic material can circumvent a harvest operation and has previously been demonstrated to be effective in o...

Description
Summary:Purpose Medial patellofemoral ligament (MPFL) reconstruction is often performed using gracilis autografts, which may be associated with donor site morbidity and complications. The use of a synthetic material can circumvent a harvest operation and has previously been demonstrated to be effective in other types of reconstructive procedures and may be effective in MPFL reconstruction. This study reports the clinical result with the use of a modern ultra-high molecular weight polyethylene with a braided jacket of polyester tape (FT) in MPFL reconstruction compared to using standard autografts. Methods Data were collected prospectively in 50 MPFL reconstructions. The first 27 underwent reconstruction using gracilis tendon (GT) autograft; the following 23 patients were treated with FT. All patients were clinically and radiologically assessed and underwent pre- and post-operative scoring using the Kujala score, Bartlett score, Tegner activity rating scale, SF-12 score and Lysholm score. Statistical significance was tested between groups using ANOVA with repeated measures. Results There were no significant differences in the pre-operative scores between the FT and GT groups (n.s.). Both groups showed significant improvements across all scoring modalities between pre- and post-operative periods 12, 24 and 48 months of follow-up ( p
