Total Knee Arthroplasty with CAOS Augmentation

A recent technology added CAOS augmentation to conventional mechanical instruments, removing the need for significant instrument relearning. The system has been shown to have a minimal learning curve and offers good usability and has been demonstrated to be non-disruptive to the surgical flow during its early adoption, reported by a subjective survey of users.


CAOS TKA Provides Improved Functional Outcomes Compared to Conventional TKA

Computer-assisted orthopaedic surgery (CAOS) has been shown to offer a clear advantage regarding surgical accuracy in total knee arthroplasty (TKA) with a body of research studies demonstrating a significant reduction of alignment outliers compared to conventional TKA instrumentation. However, conflicted data exists in the literature for a consensus regarding the advantage of CAOS technology in clinical outcomes or satisfaction rates for the patient.
