What this trial studies

This observational study aims to evaluate intra-operative and postoperative complications, long-term survivorship, and patient-reported outcome measures (PROMs) following primary total knee replacement using the Persona Total Knee system. The study will recruit 700 participants across several centers in the Nordic region, with follow-up visits planned for up to 10 years. Participants will undergo standard pain treatment and rehabilitation post-surgery, and data will be collected in accordance with local laws and regulations.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with clinical and radiological osteoarthritis of the knee who are scheduled to receive a primary unilateral total knee replacement.

Not a fit: Patients who are unwilling or unable to give consent or who have contraindications listed in the Instruction for Use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness and safety of the Persona knee system, potentially improving outcomes for patients undergoing knee replacement surgery.

How similar studies have performed: Other studies evaluating similar knee arthroplasty systems have shown promising results, indicating that this approach is supported by prior research.
