ROSA Partial Knee System

Optimise Patient Satisfaction with Confidence

The ROSA Partial Knee System provides confidence in performing partial knee arthroplasty by offering a simple technique, the clinical heritage of the Persona Partial Knee and efficiency throughout the surgical journey.


Surgeon - Centred

  • Enables confidence in performing partial knee arthroplasty thanks to a simple workflow interface
  • ROSA Partial Knee adapts to the surgeon through the collaborative mode
  • Surgeon controls the saw thus eliminating haptics
  • Compatible with Persona Partial Knee, a clinically proven and personalised knee system¹ ²


  • Enhanced patient satisfaction through accurate and reproducible surgery
  • ROSA Partial Knee offers surgeon precision and accuracy through the cut flow and validation feature, which is designed to ensure proper alignment in real time
  • Tibial resection with ROSA Partial Knee has been shown to be more accurate and reproducible than conventional instrumentation³


  • Streamlined operative steps for flexibility and ease of use
  • Proprietary 2D to 3D X-Atlas™ imaging technology to see patient bone model in the interface or image-free option to drive clinical efficiency
  • ROSA PKA requires fewer tibial cuts than convential PKA, thus potentially resulting in OR efficiencies³
  • Using ROSA Partial Knee the surgeon has the flexibility to intra-operatively change to ROSA Knee if required

Data Driven

  • ROSA Partial Knee is a cornerstone of ZBEdge, Zimmer Biomet’s integrated digital and robotic technologies purposefully engineered to deliver data-powered clinical insights across the patient journey. Part of these integrated digital and robotic technologies include ROSA Partial Knee, mymobility® with Apple Watch and OrthoIntel Orthopaedic Intelligence Platform.
  • The OrthoIntel Orthopaedic Intelligence Platform connects the pre-, intra- and post-operative data gathered through the mymobility application as well as ROSA Partial Knee to help uncover clinical insights throughout the episode of care.
