Trinity™ BIOLOX Delta™ CoC THR Multi-center Study

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01921309
Recruitment Status : Active, not recruiting
First Posted : August 13, 2013
Last Update Posted : October 27, 2020
Information provided by (Responsible Party):

Brief Summary:
To demonstrate the safety and effectiveness of the Trinity™ BIOLOX delta™ Ceramic-on-Ceramic Total Hip System in comparison to the Trinity™ Acetabular Hip System,which is FDA cleared for use in the U.S. The comparison will be based upon clinical success at the Month 24 endpoint.

Condition or disease Intervention/treatment Phase
Osteoarthritis Avascular Necrosis Rheumatoid Arthritis CDH Device: Trinity CoC Total Hip System Device: Trinity Ceramic-on-Poly THR Not Applicable

Detailed Description:

The clinical research results for the Trinity™ BIOLOX delta™ Ceramic-on-Ceramic Total Hip System will be compared to the control device

Clinical success is based upon Harris Hip Scores to evaluate functional status, adverse events, radiological assessments and no device failure (defined as removal, replacement, or modification of any device component).

Arm Intervention/treatment
Experimental: Trinity CoC Total Hip System
total hip replacement with a ceramic femoral head and ceramic acetabular cup liner
Device: Trinity CoC Total Hip System

Active Comparator: Trinity Ceramic-on-Poly THR
total hip replacement with a ceramic femoral head and polyethylene acetabular cup liner
Device: Trinity Ceramic-on-Poly THR
total hip replacement with a ceramic femoral head which moves on a highly cross-linked ultra high molecular weight polyethylene acetabular cup liner

Primary Outcome Measures :
  1. Composite Clinical Success [ Time Frame: 24 months post-operative ]
    • HHS ≥ 80 at Month 24 (good/excellent)
    • No serious, definitely device related complications with onset on or prior to Month 24
    • No radiographic failure at Month 24
    • No removal, replacement, or modification of any component on or prior to Month 24.

Secondary Outcome Measures :
  1. HHS [ Time Frame: 24 months post-operative ]
    • Individual components of the Harris Hip Score (total score, pain and function).

  2. HOOS score [ Time Frame: 24 months ]
    Hip injury and Osteoarthritis Outcome Score (HOOS).

  3. Subjective pain [ Time Frame: 24 months ]
    VAS pain score

  4. survival [ Time Frame: 24 months ]
    Kaplan-Meier survival curve

  5. adverse events [ Time Frame: 24 months ]
    Summary of device-related complications

  5. have sufficient femoral and acetabular bone stock as determined by a clinician, and are suitable to receive implants as confirmed by x-rays.

Exclusion Criteria:

  1. have a nutritional problem (protein, calorie, or vitamin/mineral deficiency) that may impair wound healing mechanisms as determined by the clinician /investigator.
  2. have a neurological disorders which may interfere or adversely affect gait, balance, or weight bearing (e.g. muscular dystrophy, multiple sclerosis).
  3. diagnosed with metabolic disorders (e.g. osteomalacia), which may impair bone metabolism.
  4. diagnosed systemic disease that would affect their welfare or the overall outcome of study (i.e. Paget's disease, renal osteodystrophy)
  5. immunologically suppressed.
  6. receiving systemic steroid therapy, excluding inhalers, within 3 months prior to surgery.
  7. diagnosed Charcot's disease, metastatic or neoplastic disease.
  8. evidence of active infections that may spread to other areas of the body (e.g. osteomyelitis, pyogenic infection of the hip joint, overt infection, untreated urinary tract infection, etc.).
  9. presence of a previous prosthetic hip replacement device (any type, including surface replacement arthroplasty, endoprosthesis, etc.) in the hip joint to be operated.
  10. previous Girdlestone procedure (resection arthroplasty) or surgical fusion of the hip to be operated.
  11. diagnosed with systemic lupus erythematosus, pigmented villonodular synovitis, juvenile rheumatoid arthritis or other diagnoses with autoimmune etiology.
