Bottom Line: There were statistical significant differences favorable to patients in Group 1 with a shorter follow-up length (2-5 years) compared to those with a longer period of 5-10 years for both Kujala and Fulkerson scores and no difference for group 2.Gender was not significant for surgical results.Moreover, group 1 patients had higher number of complications.

ABSTRACT

Background: The purpose of this study was to compare the results of two popular surgical techniques for medial patellofemoral ligament MPFL reconstruction with a minimum of two-year follow-up.

Methods: Fifty-eight patients with traumatic tear of the medial patellofemoral ligament were included in one of the two surgical groups. Group 1 MPFLs were reconstructed through graft endobutton fixation and Group 2 through graft anchor fixation into the patella. After two to five-year follow-up, patients were asked to answer knee function questionnaires (Fulkerson and Kujala) as well as the SF-36 life quality score.

Results: There were no statistical difference among postoperative Kujala, Fulkerson, and SF-36 questionnaires scores between Groups 1 and 2. There were statistical significant differences favorable to patients in Group 1 with a shorter follow-up length (2-5 years) compared to those with a longer period of 5-10 years for both Kujala and Fulkerson scores and no difference for group 2.

Conclusion: Both medial patellofemoral ligament reconstruction techniques had similar results in a two to ten-year follow-up according to functions and life quality questionnaires. Furthermore, endobutton fixation for the patellar edge of the graft had better results in patients with 2 years of follow-up than those with 5 years. Gender was not significant for surgical results. Moreover, group 1 patients had higher number of complications.

Anchor fixation on the patella ilustration. A 3 cm medialparapatellar approach is performed and a bony hollow is made atthe superomedial border of the patella where two anchors are fixedand attached sutures are used to tie the patellar edge of the tendongraft into the patella. The femoral fixation point at the free end ofthe graft is marked and fixed with an interference screw.

Figure 2: Anchor fixation on the patella ilustration. A 3 cm medialparapatellar approach is performed and a bony hollow is made atthe superomedial border of the patella where two anchors are fixedand attached sutures are used to tie the patellar edge of the tendongraft into the patella. The femoral fixation point at the free end ofthe graft is marked and fixed with an interference screw.

Mentions: Group 2 patients underwent ligament reconstruction through two metallic anchor fixation points on the patella. Diagnostic arthroscopy and graft harvesting are carried out in the same fashion as Group 1. A three cm medial parapatellar approach is performed. With the use of a small curette, a bony hollow is made at the superomedial border of the patella where two 3.2 absorbable anchors (Arthrex-PushLock ®) are fixed and attached sutures are used to tie the patellar edge of the tendon graft into the patella. The femoral fixation point at the free end of the graft is marked and fixed with an interference screw in the same fashion as Group 1 (Fig. 2). There was no concurrent medial plication procedure performed in all ligamental reconstruction.
