Various techniques for medial patellofemoral ligament MPFL reconstruction have been described with two bundles of graft tensioned simultaneously The present study was to introduce an anatomical reconstruction procedure using a horizontal Yshaped graft with respective graft tension angles and report the preliminary resultsA surgical technique for MPFL reconstruction using a horizontal Yshaped semitendinosus tendon autograft with two bundles tensioned at 0° and 30° of knee flexion was described in detail The patellar stability was evaluated with the apprehension test and an axial computed tomography CT scan at 30° of knee flexion The knee function was evaluated using the Lysholm and Kujala scoresNo recurrent dislocation or subluxation was reported for 45 patients at a mean of 337month followup On CT images congruence angle patellar tilt angle lateral patellar angle and lateral displacement were restored to the normal range At the last followup the mean Lysholm score improved from 518 ± 62 to 917 ± 41 and mean Kujala score was from 534 ± 53 to 909 ± 66 P 001The present anatomical MPFL reconstruction technique with a horizontal Yshaped twobundle graft tensioned at respective knee flexion angles could not only recreate the fanshape of MPFL but also mimic the function bundles of native ligament Clinical followup confirms the good restoration of the patellar stability and significant improvement of knee function without special complications
