摘要

Peñaherrera-Carrillo et al. recently presented a systematic review and meta-analysis in the Journal of Robotic Surgery (2026) reporting a pooled periprosthetic fracture incidence of 0.11% following tracker pin placement in 13,217 robotic- and navigation-assisted TKA procedures. Although the article highlights an important and under-reported complication, three methodological concerns directly affecting the validity of these results warrant consideration: the aggregation of biomechanically distinct robotic and computer navigation systems; the absence of bone mineral density data, which is well-documented as the primary host-side risk factor for pin-site fractures; and the omission of platform-specific differences in pin geometry, cortical engagement protocol, and drilling technique. These concerns are intended to contextualize rather than diminish the scientific value of this first comprehensive pooled dataset.
