X-3 Polyethylene Survival Outcomes Study
NCT00493792 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00493792
The ClinicalTrials.gov registry entry for NCT00493792 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 518 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Mayo Clinic, which has 3,246 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Arthroplasty, Replacement, Knee appearing as the primary indexed condition, and to 2 interventions — of which X3 Polyethylene is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00493792 reports 3 study locations spanning 3 distinct geographic areas — top geographies include Arizona, Florida, Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
