About this study

Official title: A Randomized Controlled, Multicenter Study for Patients Underwent Total Hip Arthroplasties Assisted by "VTS" Surgical Robotic System

This is a randomized controlled, multicenter study. According to the inclusion criteria, volunteers were recruited from patients undergoing total hip arthroplasty. After signing the informed consent, the subjects were assigned to the experimental group and the control group through the central randomization system. The researchers will complete the total hip arthroplasty for patients in the experimental group with the assistance of surgical robotic system. The patients in the control group do not use the surgical robotic system. The proportion of acetabular abduction angle and anteversion angle in the lewinnek safe area is the primary outcome measurement. The operation time, WOMAC score, Harris score, SF-36 and dislocation rate are the secondary outcome measurements. The incidence of complications, devices and other adverse events were recorded.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • "VTS" surgical robotic systemDevice

    The"VTS" surgical robotic system can accurately match the preoperative and intraoperative image data with the patient's anatomical structure on the operating table, track and locate the surgical instruments during the operation. With the help of the robotic arm, the surgeon can make the operation procedure more accurate and safer.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acetabular location accuracy

    Proportion of abduction angle and anteversion angle of acetabular cup in lewinnek safe area

    Measured: Within 1 week after surgery

Secondary outcomes (6)
  1. Operation time

    Time from skin incision to wound closure

    Measured: Immediately after surgery

  2. the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

    The WOMAC is a self administered questionnaire to assess joint function and quality of life for patients with osteoarthritis; it consists of 24 items: pain (5 items), stiffness (2 items), and physical function (17 items). The higher the total score, the worse the patient's pain, stiffness, and functional limitations. The WOMAC is validated for various languages, including Chinese

    Measured: 6 months after surgery

  3. Harris Hip Score (HHS)

    a rating scale with a maximum of 100 points, including the domains of pain, function, deformity, and motion

    Measured: 6 months after surgery

  4. 36-Item Short Form Survey (SF-36)

    The SF-36 is a multi-purpose survey designed to capture adult patients' perceptions of their own health and well-being.

    Measured: 6 months after surgery

  5. dislocation rate of hip joint

    the proportion of participants encountered with dislocation of hip joint after THA

    Measured: 6 months after surgery

  6. adverse events or complications

    the rate of adverse events or complications in all the participants

    Measured: 6 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing "VTS" surgical robotic system in people with Hip Arthropathy, run by Peking University Third Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acetabular location accuracy (time frame: Within 1 week after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05947734, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2023.
