Key findings

What ClinicalTrials.gov does not surface for Knee 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. Knee Osteoarthritis is recruiting above its size-band peers.

    41 of 102 indexed trials (40.2%) 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 Knee Osteoarthritis trials is spread across many organizations.

    Northwestern University accounts for 3 of 102 trials (2.9%). 77 distinct sponsors appear on at least one study for this condition label.

  3. Typical Knee Osteoarthritis enrolment sits around 83 participants.

    Median target enrolment is 83 among the 102 trials that report a genuine target (sentinel values excluded). 56 of those (54.9%) plan for fewer than 100 participants.

  4. Knee Osteoarthritis research is mostly interventional.

    88 interventional and 14 observational studies make up this index (86.3% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
