摘　　要：Background Medial patellofemoral ligament （MPFL） reconstruction is the preferred operative treatment for recurrent patellar dislocation. The purpose of this study was to report a novel suture-tie technique of patellar side fixation in medial patellofemoral ligament reconstruction for recurrent patellar dislocation, and to evaluate the intermediate-term results. Methods We retrospectively reviewed the results of 22 MPFL reconstructions in 21 patients （6 male and 15 female） with a suture-tie technique performed by a single surgeon between March 2004 and July 2009. All patients had been diagnosed with recurrent patellar dislocation. Outcomes were assessed preoperatively and postoperatively by physical and radiographic examination as well as with Kujala and Lysholm scores. Results At the mean follow-up month 37.5 （range： 24-56 months）, there was no graft failure. Primary healing was achieved in all cases. At the final follow-up, the mean Kujala score improved from 53.9 （range： 46-62 points） to 84.1 （range： 78-90 points） postoperatively （P 〈0.05）, and the mean Lysholm score improved from 47.2 points （range： 37-57 points） to 82.8 points （range： 76-89 points） postoperatively （P 〈0.05）. To date, no patients have reported redislocation or subluxation; however, there is one patient with a positive apprehension test. Conclusion A suture-tie technique in medial patellofemoral ligament reconstruction can restore patella stability without significant complication.Background Medial patellofemoral ligament （MPFL） reconstruction is the preferred operative treatment for recurrent patellar dislocation.
