Morphology
The meaning is directly compositional: 'rotatory' (involving rotation) modifies 'joint' (an articulating point), so a learner who knows both words will readily infer 'a joint that allows rotation.' This follows a straightforward adjective+noun pattern and is cross-linguistically transparent, although the precise technical detail about a single axis is a specialised nuance.
Etymology
Rotatory joint paints a simple picture: a joint that is rotatory, so it turns around a single axis like a wheel on an axle or a door on a hinge. That's why it means 'a joint that allows rotation'.
