Zimmer Biomet has announced that its Rosa Knee robotic system has surpassed 500,000 total knee arthroplasty procedures, cementing its position as one of the most widely adopted surgical robots in orthopaedic surgery.
Zimmer Biomet has announced a landmark milestone: the Rosa Knee robotic system has surpassed 500,000 total knee arthroplasty (TKA) procedures performed globally since its commercial launch in 2019.
The Rosa Knee system, which provides real-time intraoperative data, soft tissue balancing feedback and robotic arm assistance, is now installed in more than 1,200 hospitals across 45 countries.
Clinical Outcomes Data
A retrospective analysis of 120,000 Rosa Knee procedures published in the Journal of Arthroplasty demonstrated:
- Implant alignment within 1° of target: 97.8% of cases
- 30-day readmission rate: 1.8% vs. 3.4% conventional TKA
- Length of stay: 1.6 days vs. 2.4 days conventional
- Patient satisfaction at 12 months: 91.2% vs. 84.6%
Zimmer Biomet is targeting 2,000 Rosa system installations by end of 2027 and is developing a Rosa Hip module expected to launch in H2 2026.
The global knee replacement market is projected to reach $12.8 billion by 2030, with robotic-assisted procedures expected to account for 35% of all TKAs.
