VRAS (Velys Robot-Assisted Solution) Operational Excellence Study

August 20, 2024 updated by: DEO NV

Comparison Between Velys Robotic-Assisted Solution (VRAS) and Conventional Surgery in Total Knee Arthroplasty: An Operational Excellence Evaluation

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.

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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 selected countries in Europe and the UK. For each surgeon enrolled, a minimum of five VRAS assisted surgical procedures and five conventional surgical procedures will be observed. The OR set-up will be similar for all cases in the same hospital. The same experienced surgeon will conduct all procedures.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study 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.

Description

Inclusion Criteria:

  • Orthopaedic surgeons performing conventional and robot-assisted TKA

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Operational efficiency
Time Frame: 3 months

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.
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Ergonomic impaction - weight of trays
Time Frame: 3 months
Weight of trays will be measured to report ergonomic impaction of the team for the VRAS TKR compared to conventional TKR.
3 months
Ergonomic impaction - posture assessment
Time Frame: 3 months
Surgeon's posture assessment using RULA and REBA method will be executed to report ergonomic impaction for the VRAS TKR compared to conventional TKR.
3 months
Total procedure cost
Time Frame: 3 months
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.
