Patellar dislocation: osteochondral graft of patella and medial patellofemoral ligament reconstruction

OBJECTIVES: The incidence of acute femoro-patellar luxation is 6/100000 persons for year. This injury is common among young patients with predominance in women. It has high levels of recurrence (40%) after the first injury. The objective of our study is to assess post-surgical results in patients with relapsing patellar dislocation, after a reconstruction of Medial Patellofemoral Ligament (MPFL) with semitendinous autologous graft associated with autologous osteochondral transplant of patella. METHODS: An observational descriptive study (cases serie) with a restrospective transversal cross section was carried out. Six male patients that were treated between March 2014 and March 2016 were evaluated. They were monitored / followed up in an average of 24 months. The functional subjective results were assessed following Kujala patellofemoral pain score. RESULTS: Out of the six patients, all of them were male, with an average age of 19. They were followed-up for an average of 24 months. The results of the Kujala score were 86 points in the posoperative period. CONCLUSION: The reconstruction of Medial Patellofemoral Ligament (MPFL) with semitendinous autologous graft associated with autologous osteochondral transplant of patella has show excellent short and long-term clinical results with return of patients to their usual normal activities.
