| Objective This dissertation is aimed at investigating the effect of lateral patellofemoral ligament(LPFL)release on arthroscopic-assisted(MPFL)reconstruction of medial patellofemoral ligament in the treatment of recurrent patellar dislocation(RPD).Methods According to the inclusion criteria and exclusion criteria,46 patients aged 13 ~ 45 years with RPD were retrospectively analyzed from December 2014 to March 2018.Arthroscopic assisted MPFL reconstruction was performed in group M(n = 25,10 males and 15 females),and arthroscopic MPFL reconstruction combined with LPFL release was performed in ML group(n = 21,9 males and 12 females).The imaging measurement data and the changes of patellar tilt angle(PTA)before and after operation and between the two groups were compared and evaluated by Lysholm,IKDC and Tegner scoring system.Results All patients were followed up for at least 1 year,with a median follow-up of 19 months(12 ? 48 months).Postoperative fear test(-)and patellar extrapolation test(-)were performed in all patients.The scores of Lysholm,IKDC and Tegner in the two groups were compared before and after operation,and the difference was statistically significant(p < 0.05)by single factor analysis of variance(ANOVA).There was no significant difference in Lysholm,IKDC and Tegner scores between the two groups before and after operation by independent sample t test(p > 0.05).There was no significant difference in PTA angle between the two groups before and after operation by paired t test(p > 0.05),but there was no significant difference between the two groups by independent sample t test(p > 0.05).Conclusions For RPD patients who do not need bone adjustment surgery in accordance with this study,the two surgical methods have a clear curative effect and high patient satisfaction;LPFL release has no significant enhancement effect on arthroscopic assisted MPFL reconstruction in the treatment of RPD. |
