YouTube video by Dr. Charles Mok summarizing clinical findings about advanced (Level 4) arthritis. The speaker cites a large study reporting roughly 80% of patients with Level-4 arthritis avoided surgery for three years because their pain dropped by ≥50%. He compares platelet-rich plasma (PRP) and stem-cell treatments: initial PRP injections commonly produce 50–80% symptom improvement (additional injections may improve outcomes), stem-cell treatments also produce similar symptom relief but appear more durable (longer-lasting).
