@dradeel.javed: Why I Don’t Recommend Hyaluronic Acid in Grade 4 Arthritis In Grade 4 OA, the problem isn’t just lubrication—it’s severe cartilage loss and structural damage. Hyaluronic acid cannot rebuild cartilage or correct deformity and may offer only limited, or no relief at all. End-stage arthritis needs a structural solution—not just an injection. #kneearth #OrthopedicSurgery #kneepain
