Medial patellofemoral ligament reconstruction with bioactive synthetic ligament is an option. A 3-year follow-up study

Purpose The purpose of this study was to evaluate mid-term follow-up results of medial patellofemoral ligament (MPFL) reconstruction using a bioactive synthetic ligament in the treatment of objective patellofemoral (PF) instability. Methods Sixteen patients (18 knees) presenting with objective PF instability underwent a MPFL reconstruction, isolated or associated with other surgical procedures for PF stabilization. All patients were clinically evaluated at a minimum follow-up of 3 years. Kujala, subjective IKDC and KOOS scores were used to assess clinical outcome. Pre-operative and post-operative pain was quantified with VAS scale and the overall satisfaction graded according to Insall and Crosby. Although none of the patients in this series were involved in high-level sports activity because of patellofemoral instability, activity level pre-operatively and at follow-up were evaluated according to Tegner scale. Results No recurrence of dislocation was observed in this series. The overall satisfaction rate was 88.8 %. Kujala score improved significantly from 57 ± 8.4 to 84.3 ± 10.2 points ( p
