Component alignment after minimally invasive total knee arthroplasty: results of the first 100 cases performed.

Abstract

It has been suggested that minimally invasive total knee arthroplasties increase the risk of component malalignment. Results during the period of initial learning curve on component malalignment are relatively unknown but should be addressed. This study reports the component alignment data of the first 100 minimally invasive total knee arthroplasties performed by a single surgeon from the very start of a community-based practice immediately after fellowship training. The results indicate that the initial learning curve produces results comparable to reported results of standard total knee arthroplasties.
