ABSTRACT
Improvements to implant design and the advent of minimally invasive surgery have increased
the popularity of unicompartmental knee arthroplasty. Minimally invasive techniques
for implant placement can augment the unicompartmental knee arthroplasty procedure
and allow for more rapid rehabilitation and return to activities of daily living.
Nevertheless, new technologies are accompanied by learning curves and rediscovery
of past mistakes. Unicompartmental knee arthroplasty tends to be more technically
demanding than total knee arthroplasty, and complications occur with placement of
unicompartmental knee devices. This article discusses proper and improper implantation
techniques and provides technical guidance and suggestions for improving the outcomes
of unicompartmental knee arthroplasty.
