Osteochondral Lesion of the Medial Talar Dome in a Cricket Player

In cricket the ankle absorbs enormous repetitive loads. This specific motion

repetitive loads. This specific motion creates immense pressure on the talus as the foot Because the cartilage surface is still intact at this stage, the joint often

remains grossly stable, but the affected bone cannot bear load normally.

Here is the key biomechanical event.

As the ankle inverts under load, the talus rotates so that its medial dome area of subchondral bone enough to injure the bone without necessarily tearing the cartilage surface above it.

This generates a focal, high magnitude compressive load concentrated on a small impaction mechanism often from plantarflexion combined with inversion and internal

rotation.

Medial lesions like this one are typically produced by a deeper, compressive key biomechanical event. As

the ankle inverts under load, the talus rotates so that its medial dome impact is concentrated, not dissipated.

and why controlling load and addressing the injury early.
