Regenerative Cartilage Treatment at Gangnam JS Hospital
At Gangnam JS Hospital in Seoul, patients with degenerative knee conditions are experiencing breakthrough results with stem cell-based regenerative surgery—a revolutionary approach that uses umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) to repair damaged cartilage and restore mobility without the need for joint replacement.
Recognized for its excellence in orthopedic innovation, Gangnam JS Hospital has been featured in international media and cited in over 50 scientific publications. This pioneering treatment is transforming lives for patients who are not candidates for traditional knee surgery or wish to avoid implants altogether..

🔍 What Is Stem Cell Surgery for Knee Osteoarthritis?
This cutting-edge procedure utilizes umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), which are ethically sourced and extensively screened. Once isolated and cultured, these cells are injected or implanted directly into areas of cartilage damage within the knee joint.
The goal is not just symptom relief—but actual regeneration of the hyaline-like cartilage, improving mobility, reducing pain, and delaying or even eliminating the need for total knee replacement.
🧪 Backed by Clinical Evidence
The groundbreaking treatment performed at Gangnam JS Hospital is not just innovative—it is scientifically validated through a growing body of peer-reviewed clinical research. Unlike traditional pain management or joint replacement surgeries, this procedure involves the implantation of allogenic human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), which possess regenerative properties that stimulate cartilage repair and joint restoration at the cellular level.
Gangnam JS Hospital’s method is supported by peer-reviewed clinical studies published in leading medical journals:
✅ Medicina (2022): Documented successful cartilage repair in middle-aged patients using hUCB-MSCs, with MRI-confirmed regrowth of cartilage and improved joint function【file-4brFtkqWsRX34CBWy7qg2m†source】.
✅ World Journal of Clinical Cases (2022): Featured a case study of a large patellar defect successfully repaired with cord blood-derived MSCs after failure of conventional surgery【file-X94MbFH47Mh9rd7GxMYZiz†source】.
✅ Stem Cell Research & Therapy (2021): Multi-patient trials confirmed improvements in WOMAC and IKDC scores post-op, with restored hyaline cartilage verified through second-look arthroscopy【file-UsyxAbWsXDMVgWrUoD3wHh†source】.
✅ Journal of Knee Surgery (2020): Compared outcomes of this procedure to microfracture and scaffold-assisted repairs, showing superior durability and function in the stem cell group【file-FFFvrgdbzSGjzApsgaWFXU†source】.
📚 Key Clinical Findings Supporting This Approach:
✅ Histological Cartilage Regeneration:
Clinical trials confirm hUCB-MSCs successfully regenerate hyaline-like cartilage in full-thickness chondral defects. A landmark study showed well-integrated, structurally intact cartilage within just 8 weeks in a preclinical model.
✅ Sustained Clinical Improvement Over 7+ Years:
In a cohort study of 65 patients, IKDC, VAS, and WOMAC scores showed major improvements sustained for over 7 years, with MRIs confirming ongoing cartilage repair and no signs of tumor formation.
✅ Success in Elderly and High BMI Patients:
Unlike many orthopedic procedures, this stem cell treatment has shown equal effectiveness in patients over 60 years and those with BMI ≥ 30, expanding accessibility to broader populations.
✅ Large-Scale Defect Repair:
A 4.28 cm² patellar defect was fully resurfaced post-treatment. MRI at 12 months showed complete defect filling with surface congruity, and biopsy confirmed presence of type II collagen—the structural hallmark of native hyaline cartilage.
✅ Rapid Pain Reduction and Function Recovery:
In one study of 36 patients, pain and stiffness were significantly reduced within 3 months, and most returned to daily activities or light sports within 6 months.
✅ Safety and No Adverse Events:
Across thousands of procedures, no major complications, immune rejections, or infections have been recorded. This is attributed to the immune-privileged nature of hUCB-MSCs and strict donor screening and cell banking protocols.
