Background

The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, is the most complex joint of the human body, and belongs to the pulley joint. Knee osteoarthritis is the most common skeletal muscle disease and the leading cause of disability in the middle aged and elderly, and 85% total knee replacement is due to knee osteoarthritis. One of the common problems in total knee replacement is the treatment of bone defects, which may occur in tibia, femur and patella, and are mostly seen in tibial plateau bone defects, and the incidence rate of femur distal bone defects is lower than that of tibia bone defects, but the femur distal bone defects may increase the flexion-extension gap, especially the flexion-extension gap, of the knee joint. The primary reasons for total knee replacement bone defects mainly include tibial plateau abrasion, osteonecrosis, condylar dysplasia, trauma, inflammatory response and the like; the reasons for the revision of bone defects in total knee replacement mainly include arthritic, angular deformity, avascular necrosis, stress shielding, history of tibial high osteotomy or total knee replacement surgery and improper prosthesis extraction operation, or infected joint replacement, and the debridement stage of the first stage. Bone defects may also occur during total knee arthroplasty, particularly commonly seen in total knee arthroplasty revision procedures due to excessive osteotomy, infection, and improper prosthesis removal during revision. The surgeon needs to properly manage the bone defect, accurately place the prosthesis and establish a secure bone-prosthesis interface, providing adequate support for the prosthesis to achieve satisfactory surgical results.
