Osteoarthritis of HipNCT02162186
Clinical and Radiographic Outcomes of the Corin Tri-Fit Total Hip Replacement
An observational study of Osteoarthritis of Hip and Congenital Hip Dysplasia, run by Corin at 1 site in Canada.
Trial summary
The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. Read more about this study

About this study
Official title: Analysis of Clinical Outcome and Implant Migration of the Cementless Tri-Fit Total Hip Replacement System
The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.
Read the detailed description
The present study will prospectively recruit 100 patients scheduled for elective total hip replacement with Corin's TriFIT Hip System at the Ottawa Hospital - General Campus. As part of their clinical care, patients routinely undergo a clinical examination and have had radiographs taken at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery. Using specialized software, radiographs from each interval will be examined to assess femoral stem migration and joint wear patterns. Femoral stem migration will be assessed using computer-assisted software. The study will also assess the rate of implant failure during the first two post-operative years. Clinical assessments and questionnaires will also be completed during each of the follow-up intervals.

What is being measured
The primary outcome is the main question the study is designed to answer.
Femoral Stem Migration Radiographic Assessment
Femoral stem migration (in millimeters (mm)) will be assessed using computer-assisted Einzel Bild Roentgen Analyze-Femoral Component Analysis (EBRA-FCA) software and radiographs taken at each interval.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
Rate of Implant Failure
The number of revisions will be recorded.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
Radiographic Assessment of Wear in the Acetabular Components
Anterior-posterior (AP) and lateral radiographs from each follow-up visit will be used to assess wear of the acetabular (hip) components.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
Secondary outcomes (4)
Harris Hip Score (HHS)
A standardized set of questions and measurements to assess the function of the hip. It includes pain, function, range of motion (ROM), and absence of deformity.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
A standardized set of questions and measurements to assess the function of the hip. It includes pain, stiffness, and joint function.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
SF (Short Form)-12 Questionnaire
A subject-completed questionnaire with questions and he/she's health and well-being.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively
UCLA (University of California, Los Angeles) Activity Level
A subject-completed questionnaire which asks his/her current activity level.
Measured: 2 weeks to end of study (approximately 2 years) post-operatively

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jul 2020. 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 Canada. 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?
Femoral Stem Migration Radiographic Assessment (time frame: 2 weeks to end of study (approximately 2 years) post-operatively). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Jul 2020; AzTrials last refreshed its copy on 8 Nov 2026.
