Patellofemoral Relationships in Recurrent Patellar
Magnetic resonance imaging was used to analyse the patellofemoral relationships during the first 3O’ of knee fiexion in women with recurrent patellar dislocation. The patellofemoral joints were imaged both sagittally and axially with the knee flexed O , 1O , 200, and 3 O At the beginning of knee flexion the sulcus angle was greater than in unaffected women, the lateral patellofemoral angle was ...
متن کاملMedial Patellofemoral Ligament Reconstruction to Treat Recurrent Patellar Dislocation
OBJECTIVE To present a new technique for reconstruction of the medial patellofemoral ligament (MPFL) in patients with recurrent patellar dislocation and to evaluate the clinical findings from this. METHODS Between January 2007 and January 2008, 23 patients underwent reconstruction of the MPFL with a free graft from the semitendinosus tendon. After a minimum of 24 months of follow-up, 22 patie...
متن کاملMedial Patellofemoral Ligament Reconstruction for Patellar Dislocation
Results: Twenty-two studies were included: 2 randomized controlled trials, 3 parallel case series, and 17 case series. There were a total of 655 knees in the review, with an age range at time of surgery from 11 to 52 years. The pooled postoperative redislocation rate from all 17 case series showed a mean of 2.44%. The pooled preoperative Kujala scores from 12 case series showed a mean of 51.6 (...
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 کاملValgus 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...
