Official title
A Prospective, Randomized Study Comparing the Survival for X-3 Polyethylene to N2Vac Polyethylene When Used With the Triathlon Posterior Stabilized (PS) Total Knee System.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to compare two types of polyethylene (Stryker Orthopaedics N2Vac and their X3 polyethylene) prostheses that are used in total knee replacements. The primary outcome will analyze whether or not prostheses require a revision surgery 10 years post knee replacement. Other outcomes such as reoperation rate, complications, radiographic results, and clinical outcomes will be collected. It is hypothesized that X3 would perform equally well to N2Vac at 10 years.
