A tibial plateau fracture is a break at the top of the shin bone, where it forms the knee joint. The injury is treated at the knee — but a great deal of what people struggle with afterwards happens much further down, in the ankle and foot.
If you are months or even years past your fracture and your foot still swells, aches, feels numb, or simply will not tolerate a normal day, that is common and it is not something you have to accept.
