SIR, We read with interest the article by Manninen et al. [1] reporting that moderate physical exercise is associated with a decreased risk of knee osteoarthritis (OA).

ACLT, a well-known model of OA that was characterized initially in various species (e.g. dog, rabbit, monkey [2]), has recently been validated in the rat [3].
Sixty male Wistar rats (200 g) underwent ACLT
