Gait Analysis of a Lateral-Pivot Design Total Knee Replacement
NCT04275362 · View on ClinicalTrials.gov ↗
Study Summary
Previous motion analysis studies have demonstrated excellent ability to distinguish subtle differences in gait between normal subjects and those suffering from arthritis. With proper techniques and analysis differences between osteoarthritis patient groups can be distinguished. Previous research has indicated that subjects who received a single-radius design total knee replacement have superior gait performance that those who received a multi-radius design total knee replacement. The DJO Global Empowr PS Knee System is a single-radius lateral pivot design. This design should achieve reproducible more natural knee function and improved patient outcomes and satisfaction. A motion analysis laboratory will be used to collect gait data from patients who are going to receive a Empowr PS knee device and also from age-matched control subjects. These data will be compared with data previously collected from patients who received Stryker Triathlon devices, Biomet Vanguard devices and age-matched healthy control subjects.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04275362
The ClinicalTrials.gov registry entry for NCT04275362 describes a study currently listed as recruiting. It is categorized as an unspecified phase, 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 102 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is More Foundation, which has 1 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Knee Osteoarthritis appearing as the primary indexed condition, and to 4 interventions — of which Control 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: NCT04275362 reports 1 study location spanning 1 distinct geographic area — top geographies include Arizona. 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.
