Knucle Joint

Hinge Joint Did you mean "hinge joint"? The term "knucle joint" seems to be a misspelled or uncommon variation of the familiar anatomical and mechanical term. A hinge joint, as the name suggests, allows for movement in one plane, such as the joint between your elbow and forearm. In contrast, a knuckle joint would not be a recognized term in this context. Is there anything else I can help you with?
