Journal articles are general education, not medical advice, and do not create a physician–patient relationship. Articles are written or medically reviewed by Kenny Chantasi, DO; each shows its review date. Regenerative, cellular and exosome products discussed may be investigational and are not FDA-approved for orthopedic, pain or cosmetic use.
An article can explain the options. An evaluation tells you which apply to you.
Dr. Chantasi reviews your history, examines you and gives you a written plan and estimate — including when the honest answer is to wait or do nothing.
