*4.1.2 Tibia*

The Mayo classification described by Felix et al. (also known as Felix classification) is widely recognized to assess periprosthetic tibial fractures following TKA [46]. Fractures are classified into four types based on location and proximity to the prosthesis and each type is subcategorized by stability and whether the fracture occurred intraoperatively or postoperatively. The details are described in **Table 8**.
