2026年9月16日 更新者:Hip Innovation Technology

主要な人工股関節全置換術における股関節革新技術逆股関節置換術システムの安全性と有効性:ピボタル研究

The purpose of this study is to determine if the use of the HIT Reverse Hip Replacement System is safe and effective in patients undergoing total hip replacement. We will determine whether it is safe and effective by comparing it to the control devices.

調査の概要

詳細な説明

This is a randomized, controlled, multi-center clinical trial. Subjects meeting inclusion and exclusion criteria will be recruited from patients undergoing primary THA at up to 20 investigational sites. Subjects in the Experimental Arm will receive the Investigational Device. Subjects in the Control Arm will receive one of the already-marketed semi constrained uncemented hip systems using a metal on highly cross-linked polyethylene (XLPE) or ceramic-on-XLPE bearing combination. The following hip systems will be eligible for subjects in the Control Arm:

  • DePuy Synthes CORAIL® or DePuy Synthes ACTIS™ Total Hip System in combination with DePuy Synthes PINNACLE™ Complete Acetabular Hip System;
  • Zimmer Biomet Taperloc®, Zimmer Z1™ Cementless Femoral Hip Stem System or Zimmer Biomet AVENIR® Complete Hip System in combination with Zimmer Biomet G7® Acetabular System;
  • Stryker Accolade® II femoral stem in combination with Stryker Trident® II acetabular cup;
  • Smith & Nephew ANTHOLOGY® Total Hip System in combination with Smith & Nephew R3® Acetabular System.

Surgery, post-surgical care, and rehabilitation will be per standard of care (SOC) for both arms.

実験的:Experimental Arm - HIT Reverse HRS

Subjects in the Experimental Arm will receive the HIT Reverse HRS Investigational Device. Implantation of the Investigational Device is performed using standard surgical procedures for THA, as described in the Instructions for Use (IFU). The control hip systems will be implanted in accordance with their respective IFU, which are also in line with standard surgical approaches for THA.

Change in HHS compared to baseline at all follow-up visits.
時間枠:24 months

The Harris Hip Score (HHS) is a clinician-based 10-item questionnaire used to evaluate the results of hip surgery. It is comprised of 4 sub-sections yielding a maximum possible score of 100 points collectively, including pain (44 points), function (47 points), absence of deformity (4 points), and range of motion (5 points).

Measured as Cohen's effect size, the improvements of THA are in the range of 3 and higher (Singh et al., 2016). The traditional categorization of HHS is: < 70, poor; 70-79, fair; 80-89, good; and 90-100, excellent.

Exploratory Endpoints: Device survivorship
時間枠:10 year

Device survivorship is measured as a cardinal event. Any reoperation in which the entire device or part of the device has been removed or replaced will be defined as a device revision.

Exploratory Endpoints: Radiographic evaluation of linear penetration of the femoral head at the 2-year follow-up visit.
時間枠:10 year

This study requires anteroposterior (AP)-pelvis and lateral (frog-leg or Lauenstein position) views obtained in the supine position on all subjects. An additional AP-hip image will be needed only if the AP-pelvis cannot provide a complete implant image. Radiographs will be obtained at the immediate postoperative follow-up (AP-pelvis only), and at the 6-week, 6-month, 1-year, 2-year, 3-year, 4-year, 5-year, and 10-year follow-up visits. Radiographs will be transferred to the Central Radiology Lab for processing and evaluation by an independent radiologist.

10 year
Exploratory Endpoints: Metal ion level assessment of titanium, cobalt, and chromium.
時間枠:10 year

All subjects will have baseline metal ion level (Ti, Co, and Cr) identified before study THA. Further, all subjects will be monitored for metal ions (Ti, Co, and Cr) at 1-, 2-, 3-, 4-, 5-, 7-, and 10-year follow-up visits.

10 year
Exploratory Endpoints: Subject Satisfaction with Outcome.
時間枠:10 year

Subject Satisfaction with Outcome will be evaluated at the 1, 2-, 3-, 4- 5-, 7- and 10-year follow-up visits using a 4-point ordinal scale. The questionnaire will ask subjects how satisfied they are with the outcome of the surgery. The available answers will include: Very Satisfied (4); Somewhat Satisfied (3); Somewhat Dissatisfied (2); and Very Dissatisfied (1).
