Cementless Hip Resurfacing
Cemented Hip Resurfacing
Arm Description
Patients randomized into the Cementless Hip Resurfacing Group will have their hip resurfaced with the cementless Cormet / Corin Hip Resurfacing System.
Patients randomized into the Cemented Hip Resurfacing Group will have their hip resurfaced with the cemented Conserve Plus Total Resurfacing Hip System.
Outcomes
Primary Outcome Measures
Percent change in BMD (g/cm2)
The primary outcome is percent change in BMD (g/cm2) from baseline to the 1-year post-operative interval, as measured radiographically in zone L1. Analysis of periprosthetic BMD will be achieved using 6 zones of the femoral neck, which have been used in previous studies
Secondary Outcome Measures
Implant Migration
Radiographs will be taken preoperatively and until 24 months post-operatively to assess for any cup loosening. Implant migration, both vertical and horizontal, will be measured on serial radiographs using the computer-assisted Ein Bild Röentgen Analyse (EBRA) software for cup migration.
Harris Hip Score (HHS) Questionnaire
The Harris Hip Score (HHS) is intended to evaluate various hip disabilities and methods of treatment. The HHS is comprised of 4 domains: pain, function, absence of deformity, and range of motion. The score has a maximum of 100 points (best possible outcome) covering pain (1 item, 0-44 points), function (7 items, 0-47 points), absence of deformity (1 item, 4 points), and range of motion (2 items, 5 points). The total score is calculated by summing the scores for the 4 domains. The higher the HHS, the less dysfunction.
WOMAC Questionnaire to assess functionality
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) consists of 24 items divided into 3 subscales: Pain (5 items), stiffness (2 items), and function (17 items). This questionnaire is self-administered using the 5-point Likert-type scale (none, mild, moderate, severe, extreme). These correspond to an ordinal scale of 0-4. The scores are summed (0-100), where higher scores are indicative of worse pain, stiffness, and functional limitations.
RAND-36 Item Health Survey
The RAND-36 Item Health Survey assesses patient health-related quality of life and consists of 8 health concepts: physical functioning (10 items), bodily pain (2 items), role limitations due to physical health problems (4 items), role limitations due to personal or emotional problems (3 items), emotional well-being (5 items), social functioning (2 items), energy/fatigue (4 items), and general health perceptions (5 items). It also includes a single item that provides an indication of perceived change in health. Each item is scored on a 0 to 100 range, with a high score defined as a more favourable health state. Scores are averaged together to create the 8 scale scores.
UCLA Activity Score
The UCLA Activity Score will be used to assess the patients highest-rated activity, regardless of the frequency or intensity of participation. Patients are asked to select 1 out of 10 possible answers that best fit their current activity level (0-10). Low values are indicative of a sedentary lifestyle, while higher values are indicative of high impact activities.

5. Study Description
Brief Summary
The purpose of this study is to compare the bone mineral density of patients who have undergone either cemented or cementless hip resurfacing.
Detailed Description
Recent research is inconclusive regarding the degree to which the density or strength of the bone around the hip implant is preserved following a hip resurfacing system. Certainly, there are many factors which contribute to the preservation of bone mineral density - we are studying the role of cement. More specifically, we are trying to compare outcomes between patients who receive the cementless Cormet Hip Resurfacing System to those who receive the cemented CONSERVE® Plus Total Resurfacing Hip System. Therefore, the primary purpose of the current study is to compare the bone mineral density between the cementless and cemented hip resurfacing systems. We are also comparing patients who receive these two different hip systems in terms of their x-rays and how they are managing with their hip.
