Total Knee Arthroplasty (TKA) is not about “replacing the entire knee,” but rather using advanced techniques to resurface damaged bone and cartilage. It relieves pain, corrects deformities, and restores function.
You may be a candidate for total knee replacement if you experience the following conditions and conservative treatments (such as medication or physical therapy) are no longer effective:
Most common among middle-aged and elderly patients, often causing intense pain and restricted movement.
Autoimmune diseases that lead to joint structure damage.
Caused by previous fractures or ligament injuries.
Commonly known as "bow-legged" or "knock-kneed," leading to uneven joint stress.
Traditional knee replacement relies heavily on the surgeon's tactile experience, while robotic navigation systems come at a high cost.
Our approach reconstructs 3D joint models from CT/MRI data, optimized through AI-assisted planning and jointly refined by surgeons and engineers to ensure anatomical precision.
Precision doesn't have to mean expensive.
While robotic systems often exceed USD 1 million in investment with high per-case costs, our PSI solution focuses on AI planning and 3D printing—around RMB 500 per case.
Hospitals avoid costly equipment purchases, and patients benefit directly from the savings—receiving world-class precision surgery at an affordable price.
Our process is not "engineers teaching doctors," but rather doctors leading, engineers enabling.
Within the mature med-engineering collaboration model at Peking University International Hospital, your attending surgeon leads the entire process—reviewing and refining the preoperative plan with engineers in 1–2 efficient iterations.
Unlike lengthy outsourced workflows abroad, our "Chinese Efficiency" ensures rapid response and fully customized surgical plans that align 100% with clinical judgment and patient anatomy.
Ultimately, the greatest beneficiary of precision surgery is the patient.
Our precision solution not only benefits patients in China—it also meets global compliance and manufacturing standards.
The system is ready for deployment in regional 3D printing centers across the Middle East and Southeast Asia, supporting local production and regulatory requirements.
This reflects both the technical maturity and global reliability of our approach — a truly advanced solution validated by international practice.
Over 20 years orthopedic experience, 300+ knee surgeries, 20+ SCI articles, 100+ core journals.
CT/MRI scans create a 1:1 digital model of your knee joint, forming the foundation for a precise surgical plan.
Surgeon and engineers design a patient-specific 3D-printed guide using AI-assisted planning.
Precise bone cuts and implant placement using PSI, ensuring sub-millimeter accuracy.
Same-day or next-day rehab therapy to accelerate recovery and restore mobility.
Regular check-ups and monitoring to ensure lasting implant stability.
"After my bilateral knee replacement, recovery has been smooth and inflammation well-controlled. Before surgery, I never imagined this was possible — now, a year later, I can hike and cycle again. My quality of life has completely changed."
"I used to have severe bow legs — every step felt like needles in my knees. After surgery, my legs are straight again, and I was able to stand up the same day. Now I walk to the market and dance every evening — I’m more energetic than ever!"
"I injured my knee years ago, and the pain made it hard even to sleep. With this 3D-printed surgical technology, the doctor said the implant fit ‘perfectly to the bone.’ I was discharged just three days after surgery — now I’m enjoying a pain-free retirement with my family."
