Asia-Pacific expert consensus on robotic-assisted hip and knee arthroplasty

Robotic-assisted total joint arthroplasty (rTJA) has witnessed rapid adoption across the Asia-Pacific region. However, practice heterogeneity and conflicting evidence regarding its clinical value necessitate standardized guidance. Therefore, this expert consensus aims to establish consensus-based recommendations to guide and standardize the clinical application of rTJA.

The Arthroplasty Society in Asia (ASIA) convened a panel of 45 experts. A modified Delphi technique was employed across three rounds. A systematic literature review informed the generation of consensus statements, which were finalized through anonymous voting. Consensus was defined as ≥ 75% agreement.

The panel reached consensus on 18 critical clinical questions spanning general principles, total hip arthroplasty, and total knee arthroplasty. Key consensus points include: (1) rTJA demonstrates superior accuracy in implant positioning and alignment restoration compared to manual techniques (98%); (2) current evidence does not yet support a definitive superiority in long-term survivorship or PROMs (77%); (3) robotic platforms are enabling technologies that make personalized alignment philosophies technically reproducible (100%); and (4) soft-tissue balancing should take precedence over rigid mechanical alignment targets in rTKA when conflicts arise(91%).

This consensus statement provides a comprehensive framework for the application of robotic technology in hip and knee arthroplasty, emphasizing safety, precision, and the need for rigorous training.
