Abstract

Abstract:

Objective 　To investigate clinical effect of arthroscopic lateral retinacular release combined with medial patellofemoral ligament reconstruction on recurrent patellar dislocation.　Methods　19 cases were admitted into our hospital for arthroscopic lateral retinacular release combined with reconstruction the medial patellofemoral ligament from January 2012 to January 2015. With Regular follow-up after surgery, we recorded preoperative and postoperative radiographic results, Lysholm knee function score and Kujala score changes of patellofemoral joint, ligament length reconstruction.　Results　19 cases were followed up for 12~48 (25.7±8.56) months after surgery, no patella redislocation and fear patellofemoral pain syndrome, no aggravation, X-ray Q angle in the normal range were found, and the knee joint CT (at 45 °) showed that patients with the lateral patellar articular surface opening angle had it increased to (11.2±5.1)°(5°~18°) postoperatively from an average (-1.2±6.8)°(-16°~8°) preoperatively, with significant difference detected (P<0.01). Lysholm scores and Kujala patellofemoral joint score one year after surgery improved significantly compared with that prior to surgery. Average length of ligament after reconstruction immediately after operation was about (57.81±6.76) mm, and it increased to about (58.36±6.87) mm one year after surgery, with no significant relaxation found.　Conclusion　Arthroscopically assisted lateral retinacular release combined with medial patellofemoral ligament reconstruction can effectively restore the position and function of the patellofemoral joint and prevent recurrence, and the curative effect is satisfactory.
