The Dr. Joy Kong Podcast
Dr Joy Kong explains how birth tissue–derived stem cell therapy is used to treat joint osteoarthritis, including knees, and how it compares with knee replacement. She outlines the procedure, recovery process and a long-term study suggesting stem cells may reduce the need for revision surgery.

Stem Cells Instead of Knee Replacement? Dr Joy Kong Breaks It Down
Episode Overview
- Birth tissue–derived mesenchymal stem cells from placenta and umbilical cord are used, not fetal cells, and are legal and sourced from healthy live births.
- Stem cells offer anti-inflammatory, immune-modulating and regenerative signals that can wake up local cartilage and bone stem cells and help salvage damaged cells.
- Dr Joy Kong uses a dual-angle protocol: injections directly into the joint and into the bloodstream to nourish both the inner and outer portions of cartilage.
- Patients should expect mild stiffness or fullness for a few days and avoid high-impact activities for four to six weeks while fragile new tissue forms.
- A 12-year study of 30 people with osteonecrosis showed more revision surgeries in replacement knees than in knees initially treated with stem cells.
“"Think about the new tissue being very fragile, just like you're forming a new scab... so be very gentle with it."”
Ever wondered what it takes to avoid a knee replacement when every orthopaedic consult seems to point in that direction? This conversation with Dr Joy Kong shines a spotlight on how stem cell therapy may offer another route for people dealing with joint osteoarthritis and chronic knee pain. Speaking in clear, no‑nonsense language, Dr Kong walks through exactly what happens when someone comes in with joint pain looking for stem cell treatment.
She explains that the cells she uses are birth tissue–derived mesenchymal stem cells from placental and umbilical cord tissue, stressing that, "There's nothing to do with fetal cells... fetal cells are not allowed. They're not legal." These very young cells, she says, are highly anti-inflammatory, help modulate the immune system, wake up local stem cells in cartilage and bone, and can even rescue cells that are on the verge of dying.
You’ll hear how her “two‑angle” approach works: injections directly into the joint space to bathe the inner two‑thirds of the cartilage in regenerative signals, combined with intravenous delivery so the blood supply can reach the outer one‑third. She compares new tissue growth to a fresh scab – fragile at first – and urges patients to avoid high‑impact activity for four to six weeks even if they feel “kind of bionic” early on.
Dr Kong also shares a long‑term study where 30 people with osteonecrosis in both knees had one knee replaced and the other injected with stem cells. After about 12 years, six replacement knees needed revision surgery, while only one stem cell–treated knee eventually needed replacement, a result she says "offers so much hope." If you’re weighing up surgery against newer regenerative options, this straight-talking medical deep dive may help you frame better questions for your own care.
Could gentle patience with new tissue be the missing piece in your recovery plan?
