Vibration and Post-traumatic Osteoarthritis Risk Following ACL Injury
NCT04875052 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this randomized clinical trial is to evaluate the effects of vibration on factors related to the risks of post-traumatic knee osteoarthritis and secondary anterior cruciate ligament (ACL) injury in individuals who have undergone anterior cruciate ligament reconstruction surgery (ACLR). The main objectives are to compare the effects of Standard rehabilitation vs. rehabilitation that includes whole body vibration (WBV) or local muscle vibration (LMV) on: * Quadriceps muscle function * Gait biomechanics linked to post-traumatic knee osteoarthritis development * Patient self-report outcomes * MRI indicators of knee joint health and muscle quality * Landing biomechanics linked to secondary ACL injury risk * Evidence-based return-to-physical-activity criteria Participants will be assigned to 1 of 3 groups (standard rehabilitation, standard rehabilitation + WBV, or standard rehabilitation + LMV) and will complete assessments of quadriceps function, gait biomechanics, landing biomechanics, functional ability, patient-report outcomes, and MRI 1, 6, and 12 months after ACLR. Researchers will compare the groups to see if vibration embedded in ACLR rehabilitation improves joint health outcomes.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04875052
The ClinicalTrials.gov registry entry for NCT04875052 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 114 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of North Carolina, Chapel Hill, which has 725 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Osteoarthritis, Knee appearing as the primary indexed condition, and to 3 interventions — of which Experimental: Whole Body Vibration 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: NCT04875052 reports 2 study locations spanning 1 distinct geographic area — top geographies include North Carolina. 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.
