Accuracy and Learning Curve of Femoral Tunnel Placement in Medial Patellofemoral Ligament Reconstruction.

摘要: The purpose of this study was to assess the accuracy femoral tunnel placement in a medial patellofemoral ligament reconstruction (MPFL-R) cohort. secondary establish evidence learning curve achieve acceptable during MPFL-R. Two surgeons, using lateral radiographs, assessed 73 subjects post-MPFL-R. Femoral and direction error were measured relation Schottle's point (A-T distance). Interrater reliability (intraclass correlation coefficient 2,k) these measures calculated. Learning accurate examined by dividing patient cohort into quartiles. A one-way analysis variance used quartiles for position surgical time. In point, 66/73 (90.4%) tunnels categorized as being "good" or "excellent" 7/73 (9.6%) "poor" position. Evidence an MPFL-R established via statistically significant difference mean T distance four (F [3, 69] = 6.41, p = 0.001). There also time 69] = 8.71, series, placed more than 90% clear demonstrated both with respect from Schottle regard Level IV.
