A condyle (/ˈkɒndɪl, -daɪl/; Latin: condylus, from Greek: kondylos; κόνδυλος knuckle) is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. It is one of the markings or features of bones, and can refer to: Although not generally termed condyles, the trochlea and capitulum of the humerus act as condyles in the elbow, and the femur head acts as a condyle in the hip joint.
