MAKOPLASTY MEDIAL UNICONDYLAR KNEE REPLACEMENT: CORRECTION OR POSTOPERATIVE ANGLE MATTERS?

xlomafota13 shared this article with you from Inoreader

Abstract:

Introduction

There are lots of uncertainty prevails around optimal postoperative varus deformity, correction angle and physiological constitutional varus deformity. The goal of our present study was to understand correlation between these parameters and their influence over WOMAC.

Materials and methods

Consecutive robotic arm assisted medial onlay fixed bearing UKA in 143 knees studied. WOMAC score was recorded preoperatively and at specific intervals after surgery for consecutive two years.

Results

Mean preoperative and postoperative varus deformity was 10.2° and 4.8°, respectively, and mean correction angle was 5.4°. The preoperative varus and correction angles were found well correlated (r=0.815). The amount of improvement in the WOMAC total score was not influenced by the postoperative varus angle.

Conclusion

The correction angle has a stronger correlation with preoperative varus deformity, and postoperative varus deformity does not imply favourable clinical outcomes.
