Les sports fortement déconseillés sont la course à pied, le ski nautique, le football, le rugby, le handball, le hockey, le basket-ball, les sports de combat, le squash, le tennis (en simple), la gymnastique.
Tous les sports qui sollicitent violemment l’articulation, avec, notamment, des forces de torsion, sont a priori déconseillés.

Squash is a fast-moving and high-impact sport that provides an excellent cardiovascular workout but can place strain on the joints, especially the knees.
