Case Study: Hip Cartilage Regeneration Using the Patient's Own Adipose Stem Cells (Mr. Chotinai)
Background / Problem
Mr. Chotinai developed right hip osteoarthritis in his 20s after a Salmonella infection in the hip joint, which took hold while his immune system was weakened by steroids used to treat an eye condition. The infection damaged his cartilage, leaving him with pain every morning and reliant on a cane.
The first option was total hip replacement, but given his young age — and because an artificial hip lasts only about 10–15 years — the family looked for an alternative and chose treatment with stem cells from the patient's own adipose (fat) tissue.
Approach
The medical team harvested the patient's own adipose tissue, isolated the stem cells (autologous adipose-derived stem cells), and injected them back into the degenerated hip joint. The injection was performed in May 2017, followed by continuous physiotherapy and follow-up.
- 1Consult a physician and assess the treatment plan
- 2Harvest adipose tissue and isolate the stem cells
- 3Inject the stem cells into the degenerated hip joint
- 4Follow up with continuous physiotherapy
Outcomes
About 1–2 months after the injection, the daily joint pain disappeared. From barely being able to walk and needing a cane, roughly 10 months after treatment the patient could walk far more comfortably and live close to normal, with the near-daily morning pain almost entirely gone. The family says the stem cells helped restore the damaged cartilage, bringing much greater happiness to the patient and family.
- Daily joint pain resolved within about 1–2 months of treatment
- From needing a cane to walking and living close to normal again
- Returned to studying while continuing physiotherapy
Key Takeaways
- Using the patient's own (autologous) stem cells reduces the risk of immune rejection
- An option for younger patients who wish to avoid joint replacement surgery
- The patient's message: caring for and protecting your health early matters more than fixing problems later

Frequently Asked Questions (FAQs)
When do results from stem cell joint regeneration appear?
Each patient responds differently; in this case the daily pain began improving within about the first 1–2 months and continued to improve with physiotherapy. It should be done under medical supervision.
