A Simple, Stepwise, Outside-in Technique for Lateral Retinacular Release for Management of Patellar Maltracking During Total Knee Arthroplasty.

Abstract

Lateral retinacular release is done to correct patellar maltracking in total knee arthroplasty. The inside-out technique is widely used but has associated risks. Our video describes a simple outside-in technique, done stepwise, and titrated according to the grade of maltracking that maximizes preservation of the superior lateral geniculate artery and preserves the synovium, avoiding complications such as hematoma formation, skin tenting, and wound discolouration. The technique is also effective in all severities of maltracking and with all types of implants.
