What is the success rate of stem cell therapy for Knee Osteoarthritis?
No universal success rate exists. Pain is variable and placebo-responsive; review the exact product's randomised comparator, validated pain and function scales, clinically important difference, structural findings, rescue treatment, adverse events and full follow-up.
What the evidence shows for Knee Osteoarthritis
Studies should be assessed by exact product and processing, imaging guidance, comparator, baseline severity, pain and function outcomes, structural endpoints, rescue medication, adverse events and duration. The FDA consumer alert states that the promoted regenerative products it addresses have not been approved in the United States for orthopaedic conditions including knee pain and osteoarthritis.
