Morphology

cementless = cement (transparent) = cement + less

The adjective is a straightforward formation meaning 'without cement'; the medical use (implants fixed without bone cement) is a direct extension but remains inferable.

Etymology

Cementless is made from cement, the hard paste used in buildings to join stones, and the ending -less, which means 'without'. So cementless literally means 'without cement', and in medicine it describes implants held by natural bone growth instead of by cement.
