The SCUlpTOR study

We are conducting a 24-month study in Sydney and Hobart for people with knee osteoarthritis. The SCUlpTOR study - investigating the efficacy of intra-articular stem cell injections compared with a placebo.

If you qualify for the study, you will have a 50% chance of being allocated into the active or placebo group. You will not know which group you are in until the end of the study.

  • Active group: you will receive one stem cell injection at baseline, week-3 and 12-months.
  • Placebo group: you will receive one saline injection at baseline, week-3 and 12-months.


You may be eligible to participate in this study if you:

  • Are willing to stop or minimise the use of anti-inflammatory drugs (e.g. Aspirin, Nurofen, Ibuprofen, Mobic, Voltaren, etc.) and other analgesics (e.g. opioids), except for paracetamol (only for rescue pain relief) for the duration of the study. This includes stopping all pain medications for one week before each study assessment.
