What are the risks and recovery expectations?

Risks are minimal but may include temporary joint pain, swelling, or stiffness at the injection site, typically resolving within 24–48 hours. Serious complications like infection or immune reaction are rare due to strict sterile protocols. Recovery is outpatient; you can walk immediately but should avoid strenuous activity for 2–3 days after each injection. Most patients resume normal activities within a week, with gradual improvement in joint function over 3–6 months as stem cells promote tissue regeneration.
