Talus Replacement Registry
NCT03965143 · View on ClinicalTrials.gov ↗
Study Summary
Avascular necrosis of the talus is a difficult problem to manage, especially in the young and healthy. The only option, historically, has been a talectomy and hindfoot fusion. While this is a viable option, it is not without its morbidity. Arthritis of surrounding joints is common, occurring anywhere from 1-10 years after the procedure. This is especially true in younger patients, where loss of motion can be life altering both physically and mentally. The search for alternatives has been limited. Recently, 3D printing has become more ubiquitous and affordable and newer medical alternatives have arisen thanks to this technology. The 3D custom talus is relatively new in the orthopaedic community, but has been used at several centers with good success. It has been shown to re-establish the normal alignment of the foot, preserve motion (with some achieving almost physiologic motion), and allow for almost normal ambulation. However, the data is still limited and further study is necessary. Our facility was recently approved to perform this procedure. Our hypothesis is that custom 3D printed talar body replacements, either used alone or with total ankle replacements, will maintain physiologic motion, have no difference in complications when compared to hindfoot fusions with allograft, lead to good outcome scores and patient satisfaction scores. Patients diagnosed with avascular necrosis of the talus who have already decided to undergo a procedure involving a 3D custom talus as part of their standard care (talar replacement, total ankle/total talus, etc) will be enrolled in the study. Patients will follow standard post-operative protocols and return to clinic at designated time periods (2 weeks, 6 weeks, 3 months, 6 months, 1 year). X-ray evaluation, Range of motion, return to ambulation, walking speed and patient reported outcomes will be evaluated at each visit. Data will then be compared with baseline measurements and use to determine the progression of patients over ti

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03965143
The ClinicalTrials.gov registry entry for NCT03965143 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 50 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Kyle Schweser MD, which has 2 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 Avascular Necrosis of the Talus appearing as the primary indexed condition, and to 1 intervention — of which 3D talar augmentation 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: NCT03965143 reports 1 study location spanning 1 distinct geographic area — top geographies include Missouri. 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.
