Hip Replacement System (HRS-P) in Primary Total Hip Arthroplasty

Recruiting now · Not applicable

Conditions studied: Osteoarthritis of Hip

In brief

To evaluate effectiveness and safety of HHRS in subjects undergoing total hip arthroplasty (THA). Effectiveness will be evaluated using patient-reported, clinical, radiologic, and radiostereometric outcomes. Safety will be evaluated through the collection of device-related and unanticipated device-related adverse events.

Who can join

Age: 65 and older, up to 79. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patient has a non-inflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses such as osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fracture of the pelvis, and diastrophic variant requiring unilateral primary total hip replacement.
• Age between 65 and 79 years (inclusive) at the time of enrollment.
• Patient is a suitable candidate for primary total hip replacement at the discretion of the Investigator.
• Pre-surgery (within 28 days before surgery) WOMAC Global Score of 40 or larger on a scale from 0 (best) to 96 (worst)
• Signed and dated informed consent document.
• Patient is willing and able to participate in required follow-up visits at the Investigational site and to complete study procedures and questionnaires.

You may not qualify if…

• Patient has had total hip replacement, hemi-arthroplasty, or fusion in either hip in the last 12 months;
• Patient has planned total hip arthroplasty on a contra-lateral joint in the next 12 months;
• Patient has a known allergy to any component of the study device;
• Patient has a history of active sepsis in the joint;
• Patient has an insufficient acetabular or femoral bone stock in which good anchorage of the implants are unlikely or impossible;
• Patient has total or partial absence of the muscular or ligamentous apparatus;
• Patient has known moderate to severe renal insufficiency;
• Patient has vascular insufficiency, muscular atrophy, or neuromuscular disease in either leg (based on the Investigator's discretion);
• Patient has a deformity of the affected limb or significant anatomic variance of the affected hip;
• Patient has an active malignancy or history of invasive malignancy within the last five years, with the exception of superficial basal cell carcinoma or squamous cell carcinoma of the skin that has been definitively treated. Patients with carcinoma in situ of the uterine cervix definitively treated more than 1 year prior to enrollment may enter the study;
• Patient has any condition which may, in the opinion of the Investigator, interfere with the total hip replacement survival or patient outcomes (e.g. Paget's disease, Charcot's disease);
• Patient has rheumatoid arthritis or other autoimmune condition that affect joints (e.g. Lupus Arthritis);
• Patient has any condition that would interfere with patient self-assessment or pain, the function or quality of life required for patient reported outcomes during the study (based on the Investigator's discretion);
• Body Mass Index (BMI) of 40 or more;
• Patient has an active infection (e.g. hepatitis, AIDS, ARC) - systemic or at the site of intended surgery;
• Patient is currently participating in any investigational study not related to this study's pre-operative or post-operative care;
• Patient has any other severe acute or chronic medical condition that may interfere with the interpretation of the study results, in the judgment of the Investigator, which would make the patient inappropriate for entry into this study;
• Patient has a history of metabolic bone disease (e.g. Paget's disease or osteomalacia);
• Patient is currently pregnant or is planning to become pregnant.
