Which joint connects the tibia and fibula at the knee?

The connection between the tibia and fibula at the knee is established by the proximal tibiofibular joint. This joint is located near the upper end of the fibula, just below the knee, where the fibula aligns with the tibia. It plays a crucial role in providing stability and facilitating movement between the two bones, especially during activities such as walking, running, or any form of weight-bearing locomotion.

In addition, the proximal tibiofibular joint allows for slight movement, which is particularly important for proper knee function. It does not bear significant weight but contributes to the overall coordination and mechanics of the leg. Understanding this relationship helps clarify how the joints interact to support mobility and stability in the lower extremities.
