Abstract:

Objective To investigate the clinical effect of arthroscopy assisted reconstruction of medial patellofemoral ligament (MPFL), lateral retinaculum with Y-shaped release, and femoral medial muscle formation on the treatment of patellar fixation dislocation. Methods 10 patients  with 12 knees were treated with patellar fixation dislocation from January 2014 to January 2017 were retrospectively reviewed, including 6 males with 8 knees and 4 females with 4 knees. The age was from 4 to 9 years (mean 6.6 years). All patients underwent arthroscopy assisted reconstruction of the medial patellofemoral ligament (MPFL) with allogeneic ligaments, Y-shaped dissection of the lateral retinaculum, combined with femoral medial muscle formation in the treatment of patellar fixation dislocation. Postoperative follow-up was performed to assess knee functional recovery based on patellar stability and Kujala score. Degree and Kujala score were applied to assess functional recovery of knee joint. Results 10 patients were followed up for 6 to 18 months (mean follow - up of 12 months). The Kujala score increased from (42.12±14.37) to (95.68±9.42), the difference was statistically significant (P<0.05). Conclusion The use of allograft ligament in the reconstruction of medial patellofemoral ligament (MPFL), lateral retinaculum with Y-shaped release, combined with femoral medial muscle formation treatment of children with patellar fixation dislocation clinical efficacy is satisfactory, and can effectively improve patellar stability, the knee function, and the epiphyseal is not damaged, which is an effective treatment of children with patellar fixation dislocation of the surgical method.
