Valgus instability as a cause for recurrent lateral patellar dislocation: a new mechanism for patellofemoral instability?
An association between lateral patellar dislocation (LPD) and medial collateral ligament injury (MCL) has recently been demonstrated on MRI. The same valgus injury that disrupts the femoral MCL insertion can also cause a simultaneous MPFL tear at its femoral insertion, due to the close anatomical relationship of both ligamentous structures. Valgus laxity due to MCL-deficiency increases the Q-an...
متن کاملSimultaneous MPFL and LPFL reconstruction for recurrent lateral patellar dislocation with medial patellofemoral instability
We report an extremely rare case of both recurrent lateral patella dislocation and medial patellofemoral instability, following prior operations to correct patella maltracking. Manual translation of the patella revealed medial and lateral instability with a positive apprehension sign. 3-D computer modelling of kinematics based on MRI data demonstrated that the patella deviated laterally at full...
متن کاملReconstruction of the medial patellofemoral ligament for recurrent patellar instability.
Background. The purpose of this study was to compare outcomes of medial patellofemoral ligament (MPFL) repair or reconstruction. Methods. Fourteen knees that underwent MPFL repair and nine (F5, M4) knees that underwent reconstruction at our institution were evaluated for objective and subjective outcomes. The mean age at operation was 20.1 years for repair and 19.8 years for reconstruction. All...
متن کاملArthroscopic stabilization for first-time versus recurrent shoulder instability.
PURPOSE The purpose of this study was to systematically review the evidence on the outcomes of arthroscopic repair for anterior shoulder instability in first-time dislocators when compared with patients with recurrent instability. METHODS We designed a systematic review with a specific methodology to investigate the outcomes of surgery for those with only a first-time dislocation versus those...
متن کاملMedial Patellofemoral Ligament Repair Versus Reconstruction for Recurrent Patellar Instability
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...
