Corail Stability at 5-Years Post-Total Hip Arthroplasty

April 7, 2025 updated by: Brent Lanting, London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's

5 Year Migration of Collared or Collarless Corail Stems Following THA

Total hip arthroplasty (THA) is the mainstay, definitive management for end-stage hip osteoarthritis. Despite improvements of surgical and patient factors, prosthesis-related complications continue to increase in number. This is contributed to by the greater number of such surgeries being completed, larger proportion of elderly individuals among the population, and younger patient age being offered surgical intervention. Specifically, implant loosening and associated migration, is the pathology most commonly yielding revision surgery. A previous study assessing migration of total hip prostheses found that the greatest degree of migration occurred in the first 2 weeks postoperatively, although implants were considered overall stable 2 year following surgery. Continued evaluation of implant migration at time points further from surgery, specifically at 5 years postoperatively, offers insight into long term complications rates. Assessing implant migration will be completed using various imaging modalities, radiostereometric analysis (RSA) and computed tomography (CT). Comparisons between RSA and CT imaging will allow for greater analysis with regards to characterization of implant migration and associated bony changes. Additionally, an individual's gut microbiome has been shown to correspond to their inflammatory and immune profile. Association between gut microbiome profile and implant migration will be assessed to determine if underlying relationship does exist.

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

Sampling Method

Non-Probability Sample

Study Population

Patients previously recruited to a prospective RCT (NCT03558217), will be eligible to participate in this study. These patients were recruited preoperatively and underwent total hip arthroplasty using either the direct anterior or the direct lateral surgical approach. Each patient was also randomized to either receive a collared or collarless stem design. In the original study, patients were followed up until two-years postoperation, where the primary outcome measure was implant migration compared between surgical approach and implant design.

Description

Inclusion Criteria:

  • Participated in the originally investigated cohort.
  • Minimum of 4-5 years post-operation

Exclusion Criteria:

  • Pregnancy
  • Unable to attend follow-up

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Direct Anterior
Patients who underwent the Direct Anterior (DA) surgical approach
Other: Standard Post-Operative Clinic Visit
In clinic, the joint will be assessed (ROM, stability testing), standard X-rays will be taken of the joint, and patient reported outcomes (questionnaires) will be completed by patient (WOMAC, UCLA, VR12, EQ5D, Oxford Hip).
Other: Study-Specific Outcomes
Patients will complete additional questionnaires (SF12 and HHS), will undergo RSA and CT imaging for implant stability analysis, and will provide a stool sample for gut microbiome analysis.
Direct Lateral
Patients who underwent the Direct Lateral (DL) surgical approach
Other: Standard Post-Operative Clinic Visit
In clinic, the joint will be assessed (ROM, stability testing), standard X-rays will be taken of the joint, and patient reported outcomes (questionnaires) will be completed by patient (WOMAC, UCLA, VR12, EQ5D, Oxford Hip).
Other: Study-Specific Outcomes
Patients will complete additional questionnaires (SF12 and HHS), will undergo RSA and CT imaging for implant stability analysis, and will provide a stool sample for gut microbiome analysis.

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
Implant Migration
Time Frame: at 5-years post-THA
Measure implant migration that has occurred up until 5-years post-operation using RSA.
at 5-years post-THA

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.
