Native Alignment in the Setting of an Arthritic Knee in Total Knee Arthroplasty
NCT06617338 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to learn if preparing the target alignment of the operative side in total knee arthroplasty (TKA) based on the non-arthritic side will give the patient better overall alignment, function, and improved results compared to basing our implant alignment and positioning off the arthritic side, which is currently the traditional method. The main questions it aims to answer are: * Will a patient have improved postoperative TKA results if the implant alignment is based off the non-arthritic side compared to the standard arthritic side? * What are the similarities or differences between study arms with respect to final implant alignment and positioning angles? Researchers will compare the outcomes of two cohorts of patients undergoing primary robotic-assisted total knee arthroplasty (RA-TKA) with normal contralateral knee. Based on preoperative CT imaging, the researchers will use normal contralateral side joint numbers as the target alignment for one group (Experimental arm) and utilize the traditional method for the other group (Active comparator arm). Clinical outcomes and patient-reported outcome measures (PROMs) will be compared between groups. Participants will: * Be randomized into one of two study arms and will receive either a unilateral knee CT or bilateral knee CT preoperatively * Follow-up in the clinic at 2 weeks, 6 weeks and 1-year postoperatively, per standard-of-care for x-ray and clinical evaluation. * Complete postop questionnaires (PROMs) at the prescribed follow-up intervals

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06617338
The ClinicalTrials.gov registry entry for NCT06617338 describes a study currently listed as recruiting. 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 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Louisville, which has 260 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 Osteoarthritis (OA) of the Knee appearing as the primary indexed condition, and to 2 interventions — of which CT scan unilateral knee 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: NCT06617338 reports 1 study location spanning 1 distinct geographic area — top geographies include Kentucky. 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.
