Brief summary
This phase I and II double blinded randomized clinical controlled trial investigates the safety and efficacy of intraarticular knee injection with allogenic adipose derived mesenchymal stem cells (AD-MSC), in patients suffering from mild-moderate knee osteoarthritis compared to placebo injection with saline.
Interventions
Laboratory isolated, cultivated and cryopreserved allogenic adipose derived mesenchymal stem cells (AD-MSC) from health donors undergoing cometic plastic surgery will be thawed on the injection day and formulated in 10 mL saline. The AD-MSCs will then be intraarticular injected using ultrasonic guidance.
10 mL saline will be intraarticular injected using ultrasonic guidance.
