Introduction
Dr. Chai Benfu (柴本甫) is a Professor and Chief Physician in the Department of Orthopedic Surgery at Shanghai Ninth People's Hospital (上海交通大学医学院附属第九人民医院), affiliated with Shanghai Jiao Tong University School of Medicine, and one of the department's leading joint reconstruction specialists. Trained under Academician Dai Kerong, Dr. Chai has developed particular expertise in total hip and knee arthroplasty, complex revision joint replacement, and joint preservation surgery. His practice combines the technical precision of a high-volume joint replacement surgeon with the problem-solving ability required for the most challenging revision cases — including those involving massive bone defects, periprosthetic infections, and implant failures that require custom reconstruction solutions.

Clinical Excellence
- High-Volume Joint Replacement Expertise: Dr. Chai performs a high volume of primary and revision joint replacements annually, giving him the breadth of experience that translates directly into better outcomes for patients. Volume matters in joint replacement — surgeons who perform more procedures consistently achieve lower complication rates and better functional results.
- Minimally Invasive Techniques: Proficient in the direct anterior approach (DAA) for total hip replacement — a muscle-sparing technique that allows faster recovery, less pain, and earlier return to function compared to traditional posterior approaches.
- Robotic-Assisted Surgery: Experienced in robotic-assisted total knee replacement, which improves implant positioning accuracy and may improve long-term outcomes, particularly in patients with complex deformity.
- Complex Revision Mastery: Particular expertise in the most challenging revision cases — periprosthetic joint infection, massive bone defects, and implant failures — working in close collaboration with Dr. Wang Jinwu for cases requiring custom 3D-printed implants.
- Joint Preservation Philosophy: Committed to preserving the natural joint whenever possible — offering osteotomy, arthroscopy, and other joint preservation procedures to delay or avoid joint replacement in younger patients.
- International Patient Experience: Experienced in treating international patients from across Asia, Europe, and North America seeking joint replacement surgery in Shanghai.

Patient Care Philosophy
- Preserve First, Replace When Necessary: Joint replacement is a major decision — Dr. Chai explores all joint preservation options before recommending arthroplasty, particularly in younger patients.
- Right Implant for the Right Patient: Implant selection is individualized based on patient age, activity level, bone quality, anatomy, and lifestyle goals — not a one-size-fits-all approach.
- Minimally Invasive When Possible: Muscle-sparing approaches and minimally invasive techniques to reduce pain, blood loss, and recovery time.
- Infection Prevention: Rigorous infection prevention protocols — periprosthetic joint infection is the most feared complication of joint replacement, and prevention is far better than treatment.
- Rehabilitation Partnership: Joint replacement success depends as much on rehabilitation as on surgery — Dr. Chai works closely with physiotherapists to ensure optimal functional recovery.
- Long-term Commitment: Joint replacement is a lifetime commitment — Dr. Chai follows patients long-term to monitor implant performance and address any issues early.
