ABSTRACT
Tibial plateau fracture is a common acute trauma of the knee joint. At present, there are many studies on its classification and treatment, and minimally invasive treatment has become a research hotspot and mainstream direction of tibial plateau fracture. We summarized the clinical results of minimally invasive treatment of more than 300 cases of tibial plateau fractures, and proposed the concept of core weight-bearing area on tibial plateau, that is, the core weight-bearing area of the tibial plateau of the knee joint under normal motion statuswhile walking and moderate-intensity running. We performed thinsection CT scanning of the knee joint in a male volunteer for three-dimension finite element modeling.The results showed that during the walking state (the load was twice that of gravity), the core weight-bearing area of the medial and lateral plateaus was 389 mm 2 and 363 mm 2, accounting for 33.2% and 42.9% of tibial plateau, respectively;during the moderate-intensity running state (the load was four times that of gravity), the core weight-bearing area of the medial and lateral plateaus was 418 mm 2 and 406 mm 2, accounting for 35.6% and 48.0%of tibial plateau, respectively. Accordingly, tibial plateau fractures are supposed to be divided into core weight-bearing fracture and non-core weight-bearing fracture, and there are significant differences in the treatment ofthese twokinds of fractures reduction is more demanding for core weight-bearing fracture,and the fracture involves the core area closely, the anatomical reduction is sought; for non-core weight-bearing area, the reduction requirements can be appropriately low demanded, and even in some cases , for example simple avulsion fracture, marginal fracture, some tibial plateau Hoffa fractures,can be treated conservatively. In summary, during clinical diagnosis and treatmentpractice, orthopedic surgeons should take the core weight-bearing area fracture as the core of diagnosis and treatment, strictly evaluate the extent of fracture involvement, select targeted internal fixation materials, and target to promote more accurate, minimally invasive, and individualized treatment of tibial plateau fractures.
