Hospital Care Model & Joint Preservation in Japan
Unlike Western outpatient trends, Japanese healthcare emphasizes extended inpa-tient stays (up to one month for osteotomies) focusing on supervised daily physical therapy, infection control, and bone healing before returning to work. Driven by cultural values favoring biological joint preservation over total knee arthroplasty (TKA), sur-geons manage severe, active degenerative cases natively.
Complex Intra-Articular Knee Osteotomy (TCVO)
Explore high-level technical execution and planning for advanced varus deformity:
- Intra-articular realignment: Execution of Tibial Condylar Valgus Osteotomy (TCVO) combined with distal tuberosity osteotomy (DTO) to correct severe joint line convergence angles (JLCA).
- Master-class technique and material: Chisel bone cutting using auditory feed-back, patient-specific fixation plates, and customized synthetic bone grafting.
Matthieu Ollivier is currently a Professor of Orthopaedic Surgery at the Institute of Movement and Locomotion (Chairman: Pr Jean-Noel Argenson) at Aix-Marseille University Hospital, in Marseille, France. His clinical practice is dedicated to knee-related procedures, with a special focus on sports injuries (cartilage, meniscus, ligaments) and osteotomies. He is engaged in an academic field at Aix-Marseille University, teaching medical students, interns, orthopedic residents and fellows.
