Malrotation of the femoral component may cause patellofemoral complications after total knee replacement (TKR). We hypothesized that femoral component malrotation would cause excessive lengthening of the retinacula. Retinacular length changes were measured by threading fine sutures along them and attaching these to the patella and to displacement transducers. The knee post-TKR was flexed-extend...

INTRODUCTION Chronic patellofemoral instability occurs mainly in adolescent females and can also be induced by medial patellofemoral ligament (MPFL) injury. There are no case reports of MPFL reconstruction for chronic patellofemoral instability due to MPFL injury in aged populations. CASE PRESENTATION 81-year-old female presented with left knee pain, giving way, and patellar instability while...

BACKGROUND Patellar instability remains a challenging problem for both the patient and surgeon. Medial patellofemoral ligament (MPFL) repair has historically had poor results, and due to this, there is currently a trend toward reconstruction. PURPOSE/HYPOTHESIS This study was undertaken to investigate experience with repair versus reconstruction of the MPFL using a multifactorial treatment al...

BACKGROUND Several techniques are available to secure the graft to the patella during medial patellofemoral ligament (MPFL) reconstruction. The biomechanical properties of these techniques remain unknown. PURPOSE To compare the biomechanical properties of 3 MPFL patellar fixation techniques: bone tunnels (BT), PushLock anchors (PL), and tenodesis screws (TS). STUDY DESIGN Controlled laborat...

The purpose of this study was to determine the value of reconstruction of the medial patellofemoral ligament (MPFL) in the treatment of recurrent patellar dislocation and subluxation. We retrospectively reviewed 40 randomised patients with recurrent patellar dislocation or subluxation, who had undergone realignment surgery from July 1999 to December 2001. Group E consisted of 20 patients who ha...
