Knee osteoarthritis treatment in China
Full-spectrum knee OA care at Class A orthopaedic and sports medicine centres — conservative management, BMAC and PRP, and total knee replacement with international-brand implants.
Overview
Knee osteoarthritis is the most common joint disease globally and a leading cause of disability. Class A orthopaedic centres in China cover the full spectrum: structured physiotherapy, intra-articular injections (HA, PRP, BMAC), and total knee arthroplasty with international-brand implants. The cost differential vs US private pay is substantial across all stages.
Common symptoms
- Knee pain with weight-bearing, climbing stairs, or after extended activity
- Morning stiffness <30 minutes
- Reduced range of motion
- Crepitus (grinding) with movement
- Joint effusion in advanced disease
Risk factors
- Age (most common over 50)
- Female sex
- Higher BMI (each 1 kg = ~4 kg peak knee load)
- Prior meniscus or ACL injury
- Occupational repetitive loading
- Family history
Standard diagnostic workup
Cost band at Class A international department: USD 90–180 all-in.
- Standing AP + lateral knee X-rays
- MRI if soft-tissue / meniscus pathology suspected
- Functional assessment (KOOS-PS or WOMAC)
- BMI assessment, lower-extremity alignment evaluation
Treatment options
Quad-strengthening physiotherapy
Foundational — strong evidence for slowing OA progression.
Weight management
Each 1 kg lost reduces peak knee load by ~4 kg. GLP-1 medication is increasingly part of the conservative strategy.
NSAIDs / topical analgesics
First-line pharmacotherapy. Topical when systemic risks are concerning.
Intra-articular hyaluronic acid
Modest evidence for symptomatic relief in early-to-moderate OA.
PRP injection
Growing evidence for early-to-moderate OA. China price USD 200–500 per session vs USD 700–2,000 US.
Bone marrow aspirate concentrate (BMAC)
Class A sports medicine programmes (Shanghai Ninth, PKU Third). Evidence for early-to-moderate OA. USD 1,400–2,800 per knee.
Total knee arthroplasty (TKA)
Indicated for advanced OA with persistent pain and functional limitation despite conservative care. International-brand implants. USD 9,500–14,000 all-in.
Frequently asked
- How disabled am I — is surgery indicated?
- Take our KOOS-PS knee function self-test for a structured 0–100 score that orthopaedic surgeons use directly.
- Should I try BMAC or stem cell before surgery?
- For early-to-moderate OA (KL grade 2–3) with adequate functional capacity, BMAC and PRP have meaningful evidence. For advanced bone-on-bone OA, BMAC rarely changes the eventual need for arthroplasty. See our evidence reality check.
- Are international-brand implants used?
- Yes — Zimmer, Stryker, DePuy, Smith & Nephew are routinely used at Class A international departments. Domestic-brand implants are also approved if cost-prioritised.
Knee osteoarthritis function (KOOS-PS)
7-item Knee injury and Osteoarthritis Outcome Score — Physical function Short form. Used in clinical trials to track function before and after knee replacement.
