  Purpose

Primary total hip arthroplasty (THA) has been a very successful surgical intervention in the geriatric population. Numerous studies have reported good mid and long term results of THA in patients over the age of 60 years. With the reported high success rate of this surgical intervention, the THA surgery is being performed in younger patients who have significant joint disease.

A clinical trial, using a randomized blinded design, was undertaken to compare the functional outcome of 1) alumina heads/alumina liners, and 2) alumina head/Crossfire polyethylene liners in patients 60 years of age or younger with non-inflammatory arthritis of the hip.

Subjects were assessed preoperatively and at one and five years postoperatively. Ten-year follow-up is currently underway.

The primary outcome measure is the WOMAC Osteoarthritis Index. Secondary measures were the RAND-12, as well as measurement of complication and revision rates. The patient's demand on the implant as calculated by the patient's age, weight, health status and activity level was also measured.

Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Five-Year Outcome of Ceramic on Ceramic Bearing Versus Ceramic on Crossfire® Highly Cross-Linked Polyethylene Bearing in Primary Total Hip Arthroplasty: A Randomized Trial

Primary Outcome Measures:
  • Western Ontario McMaster Osteoarthritis Index (WOMAC) Pain Score [ Time Frame: Five Years ]
    This is a disease-specific, patient reported outcome measure of pain.

  • WOMAC Function Score [ Time Frame: Five years ]
    This is a disease-specific patient reported outcome measure of function

  • WOMAC Stiffness Score [ Time Frame: Five Years ]
    This is a disease-specific, patient-reported outcome measure of stiffness.


Secondary Outcome Measures:
  • WOMAC Pain Score [ Time Frame: One Year ]
    This is a disease-specific, patient-reported outcome measure of pain.

  • WOMAC Function Score [ Time Frame: One Year ]
    This is a disease-specific, patient-reported outcome measure of function.

  • WOMAC Stiffness Score [ Time Frame: One Year ]
    This is a disease-specific, patient-reported outcome measure of stiffness.

  • RAND 12-Item Health Survey (RAND-12) [ Time Frame: Five Years ]
    This is a generic patient-reported outcome measure of health status.

  • RAND-12 [ Time Frame: One years ]
    This is a generic patient-reported outcome measure of health status.

  • Complications [ Time Frame: Five Years ]
    This measured the postoperative complications.

  • Revisions [ Time Frame: Five Years ]
    This measured the number of revisions in five years

  • WOMAC Pain Score [ Time Frame: 10 Years ]
  • WOMAC Function Scores [ Time Frame: 10 years ]
  • WOMAC Stiffness Score [ Time Frame: 10 years ]
  • RAND-12 [ Time Frame: 10 years ]
  • Complications [ Time Frame: 10 years ]
  • Revision Rate [ Time Frame: 10 years ]
