Trial Outcomes & Findings for Evaluation of the Safety and Effectiveness of the Kinamed Gem Ceramic Femoral Component for Total Knee Replacement (NCT NCT00743717)

NCT ID: NCT00743717

Last Updated: 2013-05-27

Results Overview

The criterion used to assess the outcome is a Knee Score (as defined by Knee Society Clinical Rating System) \> 80 points at two-years follow-up. This scoring system is defined in the following paper: Insall JN, Dorr LD, Scott RD, and Scott WN (1989). Rationale of the Knee Society clinical rating system. Clin Orthop(248): 13-4. The scale ranges from minimum of 0 (worst) to maximum of 100 (best). Knee Score \> 80 was used as a criterion to assess "success".
