Safe and effective use of active robotics for TKA: Early results of a multicenter study.

ABSTRACT:

Background

A novel active robotic system for total knee arthroplasty (TKA) performs automated milling of bone surfaces. Study objectives were to assess system safety and effectiveness in a US population.

Methods

A multicenter clinical trial was conducted, following 115 patients for at least 6-months. A pre-defined list of robot-related adverse events was used to evaluate safety. Efficacy was assessed radiographically comparing planned versus achieved coronal limb alignment.

Results

No pre-defined adverse events occurred and postoperative limb alignment more than ±3° from plan occurred in 11.2 % of cases.

Conclusion

Active robotics for TKA is safe and effective as demonstrated in this trial.
