Research summary
The increasing number of total knee arthroplasty (TKA) procedures is putting a significant burden on healthcare systems, surgeons and their surgical teams. Technology is introduced to improve accuracy, reproducibility and efficiency of TKA surgery, and a significant portion of the patient population is now being treated using Robotic Assisted Surgery. However, robotic surgeries are believed to have a longer procedure time.
The aim of this study is to investigate the differences in process set-up, efficiency, OR team workload, instrument trays and OR financial performance when using the VRAS (Velys Robotic Assisted Solution) of DePuy Synthes compared to conventional TKA.
In this multicentre study, measurements will be conducted in 10 hospitals with 10 selected surgeons across countries in Europe and the UK. For each surgeon enrolled, data are collected through structured in-person observation of a minimum of five VRAS assisted surgical procedures and five conventional surgical procedures. Data collection will be performed either by a DEO.care engineer observing workflow in the operating room as a non-clinical observer or, where selected by the site, through anonymised-at-source video annotation.
The study is observational in nature and does not introduce any changes to clinical care or patient management. To ensure comparability, the OR set-up will remain consistent across all cases in the same hospital , and all procedures will be performed by the same experienced surgeon.
