Background/PurposeCorrect femoral tunnel position in medial patellofemoral ligament (MPFL) reconstruction is essential to maintain proper biomechanics of the patellofemoral joint throughout the range of movement. Several techniques have been described for MPFL reconstruction, however, there are few reports describing the accuracy of femoral tunnel positioning assessed postoperatively.MethodsTen patients having recurrent patellar dislocation with MPFL reconstruction performed in our centre from 2009 to 2013 were analysed. Femoral tunnel position was guided by intraoperative X-ray with landmarks described by Schottle et al, 2007. Postoperative magnetic resonance imaging (MRI) was performed on both knees, and femoral tunnel was assessed with reference to the femoral origin of the MPFL in the nonoperated side.ResultsAll cases showed an intact MPFL graft, with the majority demonstrating satisfactory femoral tunnel position based on postoperative MRI.ConclusionMPFL reconstruction with anatomic positioning of the femoral tunnel guided by intraoperative X-ray showed satisfactory accuracy in postoperative MRI results, indicating that a well-positioned MPFL graft results in better clinical outcomes. |
