The objective of the present work is to review the existing literature on joint incongruity, cellular mechano-transduction, and computer simulations of mechano-adaptive bone remodelling, and to quantitatively assess the effect of incongruity on load transmission and subchondral mineralisation. Idealised computer models of incongruous joints and a specific anatomically based model of the humero-ulnar joint articulation were analysed with the finite element method, and the results directly compared with experimental and morphological data.
