Knee Society Score calculator
About the score:
Originally published in 1989 in Clinical Orthopaedics and Related Research, the Knee Society Clinical Rating System (KSS) was designed to provide a simple and objective scoring system to rate the knee and patient’s functional abilities before and after total knee arthroplasty.
The original KSS has a “Knee Score” section (7 items) and a “Functional Score” section (3 items). Both sections are scored from 0 to 100 with lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions.
