Osteoarthritis (OA)

Basic Overview

Osteoarthritis is the most common chronic degenerative joint disease, characterized by progressive articular cartilage degradation, subchondral bone sclerosis, osteophyte formation, and synovial inflammation. It primarily affects weight-bearing joints (knee, hip), as well as the hand and spine, and is the leading cause of disability in middle-aged and elderly adults globally.

Etiology: The primary risk factor is advancing age, with additional contributing factors including obesity, joint trauma, genetic predisposition, excessive joint use, chronic inflammation, and mechanical malalignment.
Clinical Manifestations: Core symptoms include joint pain exacerbated by activity, morning stiffness lasting less than 30 minutes, joint swelling, crepitus with movement, progressive range of motion limitation, and joint deformity in end-stage disease. Severe cases present with persistent rest pain and loss of functional independence.
Diagnosis: Diagnosis is based on clinical symptoms, physical examination, and weight-bearing X-rays, with the Kellgren-Lawrence grading system used to classify radiographic severity. MRI is used to assess early cartilage damage, meniscal lesions, and synovial inflammation.

Standard Treatment Modalities

Foundational Non-Pharmacological Therapy: The cornerstone of all OA treatment, including patient education, weight management, low-impact aerobic exercise and muscle strengthening therapy, physical therapy, assistive devices (e.g., knee braces, canes), and activity modification.
Pharmacological Therapy: Used for symptom control when foundational therapy is insufficient. Interventions include topical NSAIDs (first-line for knee OA), oral NSAIDs, intra-articular corticosteroid or hyaluronic acid injections, and symptomatic slow-acting drugs for OA (SYSADOA, e.g., glucosamine, chondroitin sulfate).
Surgical Treatment: Indicated for patients with severe symptoms, progressive functional decline, and end-stage radiographic OA refractory to conservative treatment. Procedures include arthroscopic debridement, osteotomy (joint-preserving surgery for malalignment in young patients), unicompartmental knee arthroplasty (UKA), and total knee/hip arthroplasty (TKA/THA).

Core Advantages of Treatment in China

Mature Stepped-Care Personalized Treatment System

: Chinese orthopedic surgeons have established a comprehensive full-cycle stepped-care protocol for OA, from foundational therapy and pharmacotherapy to joint-preserving surgery and joint replacement. For young and middle-aged patients, knee/hip-preserving osteotomy techniques are widely standardized, effectively delaying or avoiding premature joint replacement, a key advantage over Western care that often prioritizes early arthroplasty.

Unique Integrated TCM Conservative Therapy

: China has a well-established integrated TCM-Western conservative treatment system for early and mid-stage OA, including acupuncture, tuina massage, herbal fumigation, oral and topical herbal medicine, and small needle knife release. Combined with modern rehabilitation, this approach effectively relieves pain, improves joint function, and slows disease progression, while avoiding the gastrointestinal and cardiovascular side effects of long-term NSAID use. This integrated conservative system is unparalleled globally.

World-Leading Minimally Invasive Joint Replacement Technology

: China has the highest volume of TKA/THA and UKA procedures globally, with top centers achieving a 10-year prosthesis survival rate of over 95%, equivalent to leading Western institutions. Minimally invasive arthroplasty, robot-assisted surgery, and 3D-printed personalized prostheses are widely used, with minimal trauma, less blood loss, and rapid recovery—most patients can ambulate within 24 hours postoperatively.

Extensive Experience with Complex and High-Risk Cases

: With the world's largest OA patient population, Chinese surgeons have unparalleled experience managing severe joint deformity, revision arthroplasty, and surgery in very elderly patients with multiple comorbidities. Many octogenarian and nonagenarian patients deemed inoperable in Western countries have successfully undergone joint replacement in China, with significant improvements in quality of life.

Exceptional Cost-Effectiveness and Domestic Implant Innovation

: High-quality domestic joint prostheses, which meet international advanced standards at 1/2 to 1/3 the price of imported implants, are widely used in China. The total cost of joint replacement surgery is only 1/5 to 1/7 of that in the U.S.
