What this trial studies

This multi-centre trial focuses on patients undergoing total knee arthroplasty with the Attune Cementless, Fixed Bearing, Cruciate Retaining TKA System. Participants will undergo post-operative radiostereometric analysis and CT scans to assess the migration patterns of the knee components over a period of 24 months. Additionally, patient health and functional outcomes will be monitored at various intervals, and any peri-operative complications will be documented. The study aims to provide insights into the performance and stability of the knee replacement system.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 and older with symptomatic osteoarthritis of the knee requiring total knee arthroplasty.

Not a fit: Patients with active infections, major deformities, or conditions contraindicated for the procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of knee replacement stability and improve surgical outcomes for patients with osteoarthritis.

How similar studies have performed: Previous studies using radiostereometric analysis have shown promise in evaluating joint replacements, suggesting this approach may yield valuable data.
