Arthroscopy Assisted Reconstruction Of The Medial Patellofemoral Ligament(MPFL) For Treatment Of Recurrent Patella Dislocation: An Analysis

Purpose:The purpose of this study was to evaluate the clinical effectiveness of arthroscopy assisted reconstruction of the medial patellofemoral ligament(MPFL) for the treatment of recurrent patella dislocation.Methods: During the period of time from March 2014 to December 2015, 30 patients(24 female, 6 male) suffering from recurrent patella dislocation, were operated on in the Department of Orthopedic Joint Surgery in Qinghai University Affiliated Hospital(QUAH) in Xining, with minimally invasive arthroscopy assisted reconstruction of the MPFL. All 30 cases, without loss, were followed-up during a postoperative time of 3 to 18 months by clinic examination and telephone interview. The affected knee joints were physically examined under special inspection of extrapolation experiment and fear, and radiographic patellar tilt angle(PTA) measurement were documented pre- and post-operatively. For the evaluation of the surgery’s clinical effectiveness international recognized Scores were used, like Knee Kujala Scale and Lysholm Scale(see the annex of this study: scores).Results: All investigated 30 cases showed good results in the postoperative follow-up examinations concerning the stability of the patellofemoral joint; no postoperative recurrent patella dislocation were reported. PTA(12.42±1.01), Knee Kujala Score(92.03 ±3.76) and Lysholm score(95.77 ± 3.87), showed-compared with the preoperative data- statistically significance.Conclusion : Minimally invasive arthroscopy assisted reconstruction of the medial patellofemoral ligament(MPFL) for the treatment of recurrent patella dislocation is an effective and reliable therapy option(short-term follow-up: p < 0.05) with significantly improving pain and stability of the knee joint, no complications were seen.
