Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study seeks to evaluate the initial safety and usability of new features for the ROSA® Knee System, v1.5 and plan design modifications as needed.

The primary objectives will be assessed by measuring:

1. Intra-operative complications
2. Verification that the device performs as intended
3. Overall surgeon satisfaction with the instrumentation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will involve single-arm, monocentric, cross-sectional observations conducted on the day of surgery. All assessments will take place during the pre-operative, intra-operative, and immediate postop periods on the day of surgery, with no additional follow-up beyond the procedure as robotic-assisted surgery using the current version of the robot is part of routine practice.

The safety of the system is the primary endpoint. This will be assessed by monitoring the frequency and incidence of adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified.

The secondary endpoint is defined by the usability of Zimmer Biomet ROSA® Knee System, v1.5. It will be assessed by:

1. Robotic log files to assess differences in the proposed plans by the system's new features and plan approved by the surgeon, along with time spent in the planning panel.
2. Surgeon satisfaction with the new features.
