Description of intervention(s) / exposure
This study recruits patients that have previously had a Stryker Triathlon cementless Knee Replacement with Peri-Apatite (this was a standard knee replacement procedure with a cementless device).
Patients will be asked to attend a single clinic visit (less than 1 hour duration) at a minimum 2 years post surgery. They will be asked to undertake one x-ray, and answer two questionaires that assess the pain levels, range of motion, stability, and function of the knee.
The enrolment period for this study is expected to be 3 months or until the required sample size is reached. Radiographic Evaluation will take approximately 3 months to complete, therefore it is anticipated that the entire study will take approximately 6 months to complete.
