Hip Arthropathy
Conditions
Brief summary
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 navigation system. The patients in the control group do not use the surgical navigation 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, range of motion and dislocation rate are the secondaryoutcome measurements. The incidence of complications, devices and other adverse events were recorded.
Interventions
DEVICEVTS surgical navigation system
TheVTS surgical navigation system can accurately match the preoperative and intraoperative image data with the patient's anatomical structure on the operating table, track the surgical instruments during the operation, and update the position of the surgical instruments on the patient's image in real time, so that the doctor can clearly understand the position of the surgical instruments relative to the patient's anatomical structure, and make the operation procedure more accurate and safer.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acetabular location accuracy | Within 1 week after surgery | Proportion of abduction angle and anteversion angle of acetabular cup in lewinnek safe area |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Operation time | Immediately after surgery | Time from skin incision to wound closure |
| the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | 6 months after surgery | 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 |
| Harris Hip Score (HHS) | 6 months after surgery | a rating scale with a maximum of 100 points, including the domains of pain, function, deformity, and motion |
