Comparison of Alignment Achieved Using the VELYS Robotic-Assisted Solution Versus Manual Instrumentation in Total Knee Arthroplasty
January 1, 2024 updated by: DePuy Orthopaedics
Comparison of Alignment Achieved Using the VELYS Robotic-Assisted Solution Versus Manual Instrumentation in Total Knee Arthroplasty: A Prospective, Non-Randomized Multi-Center Post-market Clinical Investigation
The purpose of this post-market research study is to gather clinical and radiographic (X-ray) information about total knee replacement surgeries completed with the VELYS Robotic-Assisted Solution and with standard manual instrumentation.
The VELYS Robotic-Assisted Solution helps the surgeon to plan bone cuts and then accurately achieve the planned cuts during the total knee replacement surgery.
The study aims to compare how well the VELYS Robotic-Assisted system enables the surgeon to position the implants exactly as planned compared to manual instrumentation.

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
Ages Eligible for Study
22 years to 85 years (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Subject is male or female and between the ages of 22 and 85 years at the time of consent, inclusive.
- Subject has a severely painful and/or severely disabled joint resulting from osteoarthritis, post-traumatic arthritis or rheumatoid arthritis and in the opinion of the Investigator, is a suitable candidate for primary TKA using the devices described in this CIP with either resurfaced or non-resurfaced patellae.
- Subject that is willing to give voluntary, written informed consent to participate in this clinical investigation and authorize the transfer of his/her information to the Sponsor
- Subject is currently not permanently bedridden, as determined by the Investigator
- Subject, in the opinion of the Investigator, is able to understand this clinical investigation and is willing and able to perform all study procedures and follow-up visits and co-operate with investigational procedures.
- Subject is able to read and comprehend the Informed Consent Document as well as complete the required PROs in English.
- Subject's pre-operative alignment is such that (in the opinion of the Investigator) it is appropriate for it to be adjusted to mechanical long leg alignment during surgery.
Exclusion Criteria:
- The Subject is a woman who is pregnant or lactating.
- Contralateral knee has already been enrolled in this study.
- Subject had a contralateral amputation.
- Previous partial knee replacement (unicompartmental, bicompartamental or patellofemoral joint replacement), patellectomy, high tibial osteotomy or primary TKA in affected knee.
- Subject has an active local or systemic infection
- Subject has loss of bone or musculature, osteoporosis, neuromuscular compromise or vascular deficiency in the affected limb in sufficient degree to render the procedure unjustifiable in the opinion of the Investigator (e.g. absence of musculo-ligamentous supporting structures, joint neuropathy)
- Subject has severe instability secondary to advanced loss of osteochondral structure or the absence of collateral ligament integrity.
- Subject has participated in a clinical investigation with an investigational product (drug or device) in the last three (3) months.
- Subject is currently involved in any personal injury litigation, medical-legal or worker's compensation claims.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Manual Arm
Subjects enrolled into this arm of the study will receive an ATTUNE primary total knee replacement that has been implanted using manual instrumentation which is the current standard of care at the participating sites.
|
Subjects will be implanted with an ATTUNE Primary total knee replacement.
|
Experimental: Robotic-Assisted Arm
Subjects enrolled into this arm will receive an ATTUNE primary total knee replacement that has been implanted with the use of the VELYS Robotic-Assisted Solution device.
|
Subjects will be implanted with an ATTUNE Primary total knee replacement.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Accuracy of Long leg Alignment
Time Frame: 12 weeks post operative
|
To determine whether the accuracy to plan of the long leg alignment achieved with the VELYS Robotic-Assisted Solution is non-inferior to the accuracy to plan of the long leg alignment achieved with the manual ATTUNE Intuition instrumentation.
This will be assessed on long-leg X-rays taken at 12 weeks.
If non-inferiority is successfully demonstrated, then the study will be deemed to be successful, and a test for superiority of mechanical axis alignment achieved with VELYS Robotic-Assisted Solution will be conducted.
|
12 weeks post operative
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Type and frequency of adverse events
Time Frame: Day of operation (intraoperative), 12 weeks, 1 year
|
Evaluate the nature, severity, and frequency of local adverse events associated with the use of the VELYS Robotic-Assisted Solution in total knee arthroplasty during the procedure and within the subsequent 12 weeks, 90 days and 1 year.
|
Day of operation (intraoperative), 12 weeks, 1 year
|
Soft tissue damage
Time Frame: Day of operation (intraoperative)
|
Investigators will conduct an intra-operative assessment of the condition and function of key soft tissue structures in both Manual and Robotic-assisted cohorts.
|
Day of operation (intraoperative)
|
Alignment Outliers
Time Frame: 12 weeks

The alignment outliers (>3 degrees outside of plan) in both Manual and Robotics cohorts will be summarized
|

|
Surgical time
Time Frame: Day of operation (intraoperative)
|
The surgical time (skin to skin), Operative time (wheels in wheels out) and total operative room utilization time will be summarized for both manual and robotic-assisted cohorts.

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Learning curve
Time Frame: Day of operation (intraoperative), 12 weeks, 1 year
|

Day of operation (intraoperative), 12 weeks, 1 year
|
EuroQol 5-Dimension 5-Level (EQ-5D-5L) - Change from baseline
Time Frame: 12 weeks, 1 year
|
The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.
The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions.
Scores are derived by a 5 digit code.
The higher the number, the better the overall health status of the patient.
|
12 weeks, 1 year
|
Forgotten Joint Score (FJS-12)
Time Frame: 12 weeks, 1 year
|
The Forgotten Joint Scores comprise measures for the assessment of joint-specific patient-reported outcome (PRO).
These PRO questionnaires focus on patients' awareness of a specific joint in everyday life.
Joint awareness can be simply defined as any unintended perception of a joint.
This may include strong sensations like pain, but also includes more subtle feelings like mild stiffness, subjective dysfunction, or any discomfort.
The FJS-12 score ranges from 0 to 100, with 0 being the worst score and 100 being the best.
A higher score means the patient is better able to forget about the artificial joint in daily life.
So, the higher the score, the better the outcome is.
|
12 weeks, 1 year
|
Knee Injury and Osteoarthritis Outcome Score (KOOS) - Change from baseline
Time Frame: 12 weeks, 1 year
|
A knee-specific instrument that derives a score developed to assess the patients' opinion about their knee and associated problems.
The maximum total score is 100 indicating no symptoms and the minimum is 0 indicating extreme symptoms.
|
12 weeks, 1 year
|
Subject Satisfaction with Knee Replacement
Time Frame: 12 weeks, 1 year
|
A single patient reported question that asks the patient to score their level of satisfaction with their knee from 0-10.
|
12 weeks, 1 year
|
Pain - Change from baseline
Time Frame: 12 weeks, 1 year
|
Subjects are asked how much knee pain they have had in the last week while resting (0-10) and during activity (0-10)
|
12 weeks, 1 year
