One-Step Autologous Cartilage Repair Surgery: Regaining Healthy Knees

Former volleyball player Ms. Chen injured her knee joints due to improper warm-uptechniques during a teaching demonstration, leading to severe pain that required her to subsequently use a wheelchair for mobility. She was diagnosed with severe cartilage wear in both knees, resulting in moderate osteoarthritis. Two years ago, she underwent "one-step autologous cartilage repair surgery," which involved filling the cartilage defects with regenerated cartilage cells, thus restoring joint function, and enabling her to return to her athletic career. Dr. Chao-Ping Chen, Director of Sports Medicine at Taichung Veterans General Hospital, explained that knee cartilage defects can occur due to injury, aging or overuse, leading to knee pain and the limiting of one's limited range of motion. If left untreated, these defects can progress to osteoarthritis, ultimately necessitating joint replacement surgery. Dr. Chen pointed out that the one-step autologous cartilage repair surgical technique is an out-of-pocket procedure that uses the patient's own healthy cartilage. During surgery, approximately 2 to 5 grams of healthy cartilage are harvested from a non-weight-bearing area of the knee. This cartilage is then minced and treated with special enzymes to release a large number of cartilage cells, which are then implanted into the cartilage defect to promote the regeneration of durable hyaline-like cartilage. Early diagnosis and treatment are recommended, with the surgery touting a success rate of up to 90%. Ms. Chen, the former athlete, had been diagnosed with bilateral knee cartilage defects with moderate osteoarthritis. Without treatment, she may have required artificial joint replacement within 5 to 10 years. After undergoing the one-step autologous cartilage repair surgical technique in both knees, Ms. Chen was eventually able to return to the volleyball court and regain her athletic life. A second patient, Mr. Huang, 52, had been diagnosed with damaged knee cartilage due to repeated impact with machinery during his youth. The patient ignored the pain until he could no longer ride a bicycle, and was eventually diagnosed with osteoarthritis. He underwent the one-step autologous cartilage repair surgery 12 years ago and was then able to resume cycling, accumulating over 100,000 kilometers with no physical issues during his high-intensity training regimen. An additional case regarding this surgical technique involved Mr. Luo, a 75-year-old farmer who suffered a car accident in his youth and later developed cartilage defects in his knees after retirement. After the surgery was performed over a year ago, he was able to return to farming. Dr. Chen emphasized the importance of seeking a medical evaluation if you experience knee discomfort, swelling after prolonged activity, or restricted movement. Early diagnosis and treatment remain crucial, while regular muscle-strengthening exercises can protect the knee joints. It is also recommended that the elderly engage in brisk walking on flat surfaces for 40 minutes, four times a week. Current treatments for joint cartilage defects include medication, hyaluronic acid injections, autologous platelet therapy, and joint replacement surgery. The one-step autologous cartilage repair surgery is now also available as an additional treatment option.
