Key findings

What ClinicalTrials.gov does not surface for Osteoarthritis on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Osteoarthritis is recruiting below its size-band peers.

    29 of 136 indexed trials (21.3%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Osteoarthritis trials is spread across many organizations.

    Zimmer Biomet accounts for 12 of 136 trials (8.8%). 87 distinct sponsors appear on at least one study for this condition label.

  3. Typical Osteoarthritis enrolment sits around 160 participants.

    Median target enrolment is 160 among the 136 trials that report a genuine target (sentinel values excluded). 45 of those (33.1%) plan for fewer than 100 participants.

  4. Osteoarthritis research is mostly interventional.

    106 interventional and 30 observational studies make up this index (77.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
