Can Original Knee Society Scores Be Used to Estimate New 2011 Knee Society Scores?

ABSTRACT:

Background

The Knee Society Score (KSS) instrument is one of the most commonly reported primary outcome measures for total knee arthroplasty (TKA). Originally developed in 1989, the KSS was expanded and updated in 2011; however, the original KSS does not directly translate into the 2011 KSS. To date, no conversion algorithm has been developed, hindering the ability of researchers to adopt the 2011 KSS while maintaining their historical/longitudinal original KSS data.

Questions/purposes

The purpose of this study is to develop regression equations to map the original KSS to the 2011 KSS, allowing original and 2011 KSS data sets to be combined.

Methods

In this multicenter, nonrandomized study, a convenience sample of 815 patients undergoing primary TKA completed the orig
