“RSA of the ATTUNE Knee System: RCT Comparing Traditional Vs Enhanced-Fixation Device Designs”
The principal objective of this study is to compare migration patterns between the Attune and Attune S+ PS knee systems using model-based RSA over the first 2 post-operative years. Secondary objectives include; comparison of 2-year migration values against published thresholds for adequate short-term fixation, quantify changes in functional and health status of subjects following surgery and compare between study groups, and assess occurrences of complications following surgery.
Device - ATTUNE PS Knee
The ATTUNE PS Knee is the standard implants.
Device - ATTUNE S+ PS Knee
The ATTUNE S+ PS Knee is the enhanced fixation.
