Initial Experience with the NAVIO Robotic-Assisted Total Knee Replacement-Coronal Alignment Accuracy and the Learning Curve

Kade Collins et al.

Summary: The primary aim of this study was to investigate the efficacy of a robotic-assisted system in coronal plane component positioning in total knee arthroplasty (TKA), with 93.3% of cases achieving the desired alignment within 3 degrees of neutral. A learning curve effect was not found in the adoption of this new technology, suggesting that the robotic-assisted system produced accurate coronal alignment in TKA in over 93% of cases without a learning curve effect.

Daniel Steffens et al.

Summary: The study compared the in-hospital costs of robotic-assisted and computer-navigated total knee arthroplasty (TKA), finding that there was no significant difference in total in-hospital cost when excluding the capital costs of surgical equipment and maintenance. However, robotic-assisted TKA was more expensive when including these upfront costs. Further research is needed to investigate the long-term cost benefit of robotic-assisted TKA.

Contemporary Robotic Systems in Total Knee Arthroplasty A Review of Accuracy and Outcomes

Shuyang Han et al.

Summary: The success of total knee arthroplasty relies on the correct positioning and alignment of prosthetic components, matched to each individual patient's anatomy and soft tissue properties. While early results suggest gains in patient outcomes using robotic technologies, long-term evidence is still awaited from multicenter prospective clinical trials. Advancements in technology are needed to address knee laxity and customize functional performance.

The current state of robotics in total knee arthroplasty

Jean-Pierre St Mart et al.

Summary: Robotic total knee arthroplasty (TKA) has advantages in improving component positioning and reducing alignment outliers, especially with current semi-active systems that incorporate haptic feedback to minimize iatrogenic soft tissue injury. However, limitations of current robotic technology include high upfront costs, steep learning curves, and lack of long-term outcomes. Short-term gains and technical reliability associated with current systems may justify continued investment in robotic technology, but further long-term data are needed to fully determine the cost-effectiveness of newer robotic systems.

Cecile Batailler et al.

Summary: The study evaluated the interest and usage of assistive technologies in modern knee arthroplasty, finding that these technologies do not follow the traditional "Scott Parabola" as described in literature. Computer-assisted knee arthroplasty and patient-specific instrumentation have reached a plateau in terms of publications, while research on robotic surgery, accelerometers, and sensors continues to increase. The proportion of primary total knee arthroplasty performed with computer-assisted systems has shown significant increases in registries such as Australia and Norway.
