The medial condyle is one of the two protrusions on the bottom end of the femur that help form the knee joint, according to the University of Glasgow Laboratory of Human Anatomy. The femur is the thigh bone, explains Healthline.
The condyles on the femur meet and move with the top end of the tibia or shin bone, notes the University of Glasgow Laboratory of Human Anatomy. The size of the condyles and the angle at which they meet the tibia determine how well the knee flexes and rotates, reports Wheeless' Textbook of Orthopaedics. Located on the inner side of the femur, the medial condyle is bigger and rounder than the lateral condyle, which is on the outer side of the bone.
