Stem cell therapy for knee pain gives patients with arthritis or joint damage a path around the operating room. RegenHaus Medical in Alpharetta, GA, uses this regenerative treatment to calm inflammation and support the knee’s own repair process.
This guide covers how stem cell knee injections work, what the research shows, and who makes a good candidate. You’ll also find real cost numbers and a side-by-side comparison against surgery, PRP, and cortisone shots.
Key Takeaways
- Stem cell therapy for knee pain uses your own cells to calm inflammation and support joint repair, without surgery.
- A 2023 Emory Healthcare study found stem cell injections relieve knee pain about as well as corticosteroid shots at the one-year mark, not better.
- Good candidates have mild to moderate arthritis. Severe, bone-on-bone knees respond poorly.
- Stem cell knee injections cost $2,500 to $10,000 per knee, and most insurance plans do not cover the procedure.
- RegenHaus Medical in Alpharetta, GA offers stem cell knee injections. Call (404) 424-4068 to book a consultation.
What Is Stem Cell Therapy for Knee Pain?
Stem cell therapy for knee pain is a regenerative injection that places your own cells directly into the joint to reduce inflammation and support cartilage repair. Doctors pull mesenchymal stem cells, a type of stem cell for joints, from two sources: bone marrow in the hip bone or fat tissue from the abdomen. RegenHaus Medical collects the sample during the same visit as the knee injection. The full process takes 60 to 90 minutes, and patients walk out the same day. See our full stem cell therapy program for a step-by-step breakdown.
Does Stem Cell Therapy for Knee Pain Actually Work?
Stem cell therapy for knee pain reduces symptoms for many patients, but it does not outperform standard treatment at the one-year mark. A study from Emory Healthcare tracked pain scores in knee osteoarthritis patients for a full year and compared stem cell injections against corticosteroid shots.
The result: stem cell therapy performed about the same as corticosteroids at 12 months, not better. Both groups reported real pain relief. Neither treatment reversed the underlying arthritis. RegenHaus Medical shares this data with every Alpharetta patient so expectations stay realistic before treatment begins.

Conditions Treated with Stem Cells for Knee Pain
Stem cell therapy treats three common knee problems: osteoarthritis, meniscus tears, and ligament damage.
- Osteoarthritis: cartilage wear that causes stiffness, swelling, and grinding pain in the knee joint.
- Meniscus tears: damage to the cartilage cushion between the shinbone and thighbone, common in athletes and older adults.
- Ligament injuries: partial tears of the ACL or MCL that have not fully separated the ligament.
Stem Cell Knee Injection vs. Surgery, PRP & Cortisone
A stem cell knee injection sits between low-cost, short-term options like cortisone and high-cost, long-term fixes like knee replacement surgery. The table below compares the four most common paths for knee pain. For a closer look at how the cell-based options differ from each other, see PRP vs. Bone Marrow vs. Umbilical Cord Tissue: A Plain Comparison.
| Treatment | Average Cost (per knee) | Recovery Time | Evidence Strength |
| Stem Cell Injection | $2,500–$10,000 | 1–3 days | Moderate, pain relief similar to cortisone at 1 year |
| PRP Injection | $500–$2,000 | 1–2 days | Moderate, short-term pain relief |
| Cortisone Injection | $100–$300 | Same day | Strong, short-term relief, wears off in weeks |
| Knee Replacement Surgery | $30,000–$50,000 | 6–12 weeks | Strong, long-term fix for severe arthritis |
Am I a Good Candidate for Stem Cell Therapy?
Good candidates for stem cell therapy have mild to moderate knee osteoarthritis, a partial meniscus tear, or a ligament sprain that has not fully torn. Patients with bone-on-bone arthritis, classified as Kellgren-Lawrence grade 3 or 4, typically see limited results because there is little cartilage left to support. RegenHaus Medical reviews knee imaging during the first Alpharetta consultation to confirm candidacy before scheduling a knee injection. If you’ve been told your knee is “bone-on-bone,” our article on what that phrase actually means is worth reading before you rule anything out.
What to Expect During the Procedure and Recovery
The stem cell knee injection procedure starts with a local numbing agent, followed by cell collection from the bone marrow or fat tissue, and ends with the injection into the knee joint under ultrasound guidance. Most patients return to light activity within 1 to 3 days. Full results build over 6 to 12 weeks as the cells work. RegenHaus Medical schedules a follow-up visit at the 6-week mark to track progress. Read patient questions on our stem cell procedures FAQ page.
Risks, Safety & FDA Regulatory Status
The FDA has not approved stem cell injections for knee osteoarthritis. Clinics offer the procedure under minimal manipulation guidelines that allow use of a patient’s own cells without full FDA approval. Reported risks include injection site pain, swelling, and infection, all uncommon. RegenHaus Medical uses only autologous cells, meaning the cells come from the patient’s own body, which lowers the risk of rejection or allergic reaction. If cortisone is the alternative you’re weighing, see The Cortisone Cycle: Why Repeated Shots May Be Working Against You for the tradeoffs of relying on it long-term.
Cost of Stem Cell Therapy for Knee Pain
Stem cell knee injections cost $2,500 to $10,000 per knee, depending on the cell source and number of injections. Most insurance plans classify the treatment as experimental and deny coverage. RegenHaus Medical offers a payment plan and provides an exact quote after the Alpharetta consultation. Learn more about pricing and financing on our regenerative treatments page.

How long do stem cell injections last for knee pain?
Stem cell injections for knee pain typically ease symptoms for 6 to 12 months, with some patients reporting relief for two years or longer.
What are stem cells for joints made from?
Stem cells for joints come from the patient’s own bone marrow or fat tissue, collected during the same visit as the knee injection.

Most patients feel a brief pinch and pressure during the knee injection. RegenHaus Medical numbs the area first to limit discomfort.
How much does stem cell knee surgery cost?
Stem cell knee injections cost between $2,500 and $10,000 per knee, depending on the cell source and number of injections needed.
