About this trial
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.

Trial population
The 10 participants of the study are orthopaedic surgeons. They will execute at least 5 conventional TKA procedures and at least 5 VELYS robot-assisted TKA procedures. This study is observational, with a focus on operational excellence, and as such DEO.care will not influence surgeon's decisions with regards to surgical technique philosophies. Surgeon will select the relevant techniques for each case at his/her own discretion.

Treatments tested in this trial
Robotic-assisted TKA
Procedure/SurgeryRobotic-assisted Total Knee Arthroplasty or total knee replacement is a surgical procedure using a robot to resurface a knee joint damaged with arthritis, and where the knee joint of the patient is replaced with a prosthesis.
Conventional TKA
Procedure/SurgeryConventional Total Knee Arthroplasty or total knee replacement is a surgical procedure to manually resurface a knee joint damaged with arthritis, and where the knee joint of the patient is replaced with a prosthesis.
Treatment groups
Trial outcomes
Primary outcomes
Operational efficiency
Efficiency will be assessed using OR time, by comparing the OR days and procedures where TKR is performed conventionally or by using VRAS surgery. A granular analysis from the timestamps will be conducted using standard descriptive statistics. Additionally, the impaction process will be further analyzed, broken down into parts.
Secondary outcomes
Ergonomic impaction - weight of trays
Weight of trays will be measured to report ergonomic impaction of the team for the VRAS TKR compared to conventional TKR.
Ergonomic impaction - posture assessment
Surgeon's posture assessment using RULA and REBA method will be executed to report ergonomic impaction for the VRAS TKR compared to conventional TKR.
Total procedure cost
The procedure cost differences between VRAS TKR and conventional TKR will be calculated using activity based costing modeling. This model will include fixed direct, fixed indirect, and variable costs, tailored to each country's local cost parameters and healthcare financing models.
