Clinical and Radiographic Outcomes of the Corin Tri-Fit Total Hip Replacement

July 13, 2020 updated by: Corin

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The first 100 patients Dr. Paul Beaule undergoing a total hip replacement with Corin's TriFIT Total Hip replacement system that meet the eligibility requirements and consent to do the study.

Description

Inclusion Criteria:

  • Patients scheduled for primary, unilateral total hip replacement (THR) with no previous history of hip replacement and/or fracture surgery.
  • Patients with arthritis secondary Noninflammatory Degenerative Joint Diseases (NIDJD), including osteo/degenerative arthritis, congenital hip dysplasia, and avascular necrosis.
  • Patients who do not meet any of the exclusion criteria.

Exclusion Criteria:

  • Patients with previous fusions, acute femoral neck fractures, above knee amputations, or previous total knee replacement.
  • Patients who had previously undergone an ipsilateral hemi resurfacing, total resurfacing, total bipolar, unipolar or total hip replacement device.
  • Patients with neuropathic joints.
  • Patients who required structural bone grafts.
  • Patients with an ipsilateral girdlestone.
  • Patients who otherwise met the study criteria, but for which appropriate clinical follow-up data is not available (i.e. patients deceased prior to 2-year follow-up, patients refused to return for follow-up).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Femoral Stem Migration Radiographic Assessment
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
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.
2 weeks to end of study (approximately 2 years) post-operatively
Rate of Implant Failure
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
The number of revisions will be recorded.
2 weeks to end of study (approximately 2 years) post-operatively
Radiographic Assessment of Wear in the Acetabular Components
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
Anterior-posterior (AP) and lateral radiographs from each follow-up visit will be used to assess wear of the acetabular (hip) components.
2 weeks to end of study (approximately 2 years) post-operatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Harris Hip Score (HHS)
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
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.
2 weeks to end of study (approximately 2 years) post-operatively
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
A standardized set of questions and measurements to assess the function of the hip. It includes pain, stiffness, and joint function.
2 weeks to end of study (approximately 2 years) post-operatively
SF (Short Form)-12 Questionnaire
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
A subject-completed questionnaire with questions and he/she's health and well-being.
2 weeks to end of study (approximately 2 years) post-operatively
UCLA (University of California, Los Angeles) Activity Level
Time Frame: 2 weeks to end of study (approximately 2 years) post-operatively
A subject-completed questionnaire which asks his/her current activity level.
2 weeks to end of study (approximately 2 years) post-operatively

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
