Hip Osteoarthritis: cell-therapy evidence by therapy class
Across every stem-cell intervention, ClinicalTrials.gov holds 12 registered records for Hip Osteoarthritis — 3 recruiting, 0 at Phase 3 or 4, in 5 countries. Snapshot 2026-08-29.
The condition, and why cells are proposed
Hip osteoarthritis involves cartilage loss in a deep, high-load joint with limited access for injection and less intra-articular volume than the knee. Registered cell work is markedly thinner here than for knees, which is a useful cross-check when a clinic quotes knee data to justify a hip procedure.
Therapy classes side by side
Counts come from separate registry queries per class; a study testing two interventions can appear in more than one row, so rows do not sum to the all-interventions total.
Geography of the research
United States accounts for about 45% of country mentions among sampled studies; 5 countries host at least one site.

The largest registered studies
Sorted by planned enrolment — size is not quality, but a 300-participant trial can answer questions a 12-participant series cannot.

Reading this honestly
Registration counts measure activity, not effect. A study appears here the moment it is registered — before any participant is enrolled, and regardless of whether results are ever posted. For Hip Osteoarthritis specifically, the practical question is which registered study — if any — matches the product a provider is offering, and what its outcome measures actually are.
Frequently asked
How many stem-cell trials exist for Hip Osteoarthritis?
12 registered records mention a stem-cell intervention for this condition (2026-08-29 snapshot), of which 3 were recruiting.
Which therapy class is furthest along for Hip Osteoarthritis?
Ranked by Phase 3/4 records: PRP (3), MSC (0), HSCT (0), exosomes (0).
Does a recruiting trial mean I can be treated?
No. Trials have eligibility criteria, and joining one is not the same as buying a treatment. Paying a clinic for an unproven intervention outside a registered study gives you neither the protections nor the data collection of a trial.
