Functional outcome analysis for habitual patella instability treatment by MPFL advancement technique

Abstract

Aim: Evaluation of functional outcome following medial patellofemoral advancement surgical procedure in habitual patellar dislocation.Material and method: Prospective study was conducted in the department of orthopedic surgery at Keshav Porwal multispecialty Hospital, Bhilwara, Rajasthan among 24 patients from January 2018 to January 2020. All cases underwent proximal realignment surgery for habitual patellar dislocation with minimum follow-up of 6 months and maximum follow-up of 24 months. Radiological assessment was done using sulcus angle and congruence angle, pain was assessed with VAS scale.Results: Mean age of the study group was 19.14 years. Among them 58.3%were male and 41.7% were female. Mean pre-operative sulcus angle was 132.06 degree and post-operative was 132.39 degree. Congruence angle pre-operative was 62.86 degree and post-operative was 17.81 degree. VAS score preoperatively and postoperatively were 6.16 and 3.01 respectively. Conclusion: we conclude that following MPFL advancement surgery radiological parameters were brought back to normal anatomical position with painless functional outcome.
