Country distribution
| Country | Studies with a site there |
|---|---|
| South Korea | 4 |
| United States | 4 |
| China | 2 |
| United Kingdom | 1 |
| Spain | 1 |
A study with sites in several countries is counted once per country, taken from the location block of each registry record.
What the map means for Tendon & Sports Injuries
Sports-medicine studies concentrate in Europe, North America and Australia, alongside a large private injection market. Elite-athlete anecdotes circulate globally and carry no evidential weight, since athletes receive many concurrent interventions.

What travelling for a trial actually involves
If a site is abroad, the practical questions are who provides follow-up at home, what happens if an adverse event occurs after you fly back, and whether the protocol permits remote assessment at all. Most do not.
Multi-country studies, named
Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.
No sampled study for this condition lists sites in more than one country, so the research base here is made of single-centre work rather than multinational collaboration.
Why trial geography is not a shortlist
Where studies happen reflects who funds and who authorises them. Treating that as a ranking of care quality confuses the research system with the treatment market, two things that overlap far less than medical-tourism marketing implies.
Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.
When these studies started
Registrations by start year since 2020: 2022 (1), 2023 (2), 2024 (1), 2026 (2). Activity for this condition spans 2009 to 2026, which shows whether interest is growing, flat or past its peak.
Frequently asked
Which countries run stem-cell trials for Tendon & Sports Injuries?
Sites are registered in 5 countries; the largest is South Korea (~33% of country mentions, 2026-08-29).
Does a country with many trials mean better treatment there?
No — trial counts describe where research is permitted and paid for. Care quality is decided at the level of the individual provider and product.
Are trial sites and commercial clinics the same thing?
They are generally distinct. Proximity in a city or even a shared address does not make a commercial clinic part of a registered protocol — ask for the identifier.
