| Popis: | Background: Few studies to date have compared clinical outcomes in patients who have undergone medial patellofemoral ligament (MPFL) reconstruction using the suture anchor and double transpatellar tunnel fixation methods. This meta-analysis therefore compared the clinical results, including the patellar redislocation rate and improvement in functional scores, of suture anchor and double transpatellar tunnel fixation. Hypothesis: The recurrence rate and improvement in functional outcomes after surgery would be similar using the suture anchor and double transpatellar tunnel fixation methods. Study Design: Meta-analysis. Methods: Studies evaluating MPFL reconstruction using either the suture anchor or double transpatellar tunnel technique for patellar site fixation were included if they reported the patellar redislocation rate after surgery and/or validated patient-reported outcomes such as the Kujala and Lysholm scores. Results: Twenty-one studies were included in this meta-analysis. The mean patellar redislocation rates were similar using the suture anchor (3.2% [95% CI, 1.6%-6.2%]) and double transpatellar tunnel (3.4% [95% CI, 2.1%-5.4%]) techniques ( P = .879). The mean improvement in the Kujala score from before to after MPFL reconstruction was greater using the suture anchor (37.2 [95% CI, 31.1-43.4]) method than the double transpatellar tunnel method (28.7 [95% CI, 21.2-36.1]) ( P = .018). However, the mean improvement in the Lysholm score did not differ significantly using the 2 techniques. Conclusion: The patellar redislocation rate did not differ significantly in patients who underwent MPFL reconstruction using the suture anchor and double transpatellar tunnel fixation methods. The suture anchor fixation method, however, resulted in a greater degree of improvement in patient-reported outcomes. |
