Thunderbolt Pose - Vajrasana

 Thunderbolt Pose Vajrasana is a kneeling asana in hatha yoga.

Some orthopaedic surgeons claim Vajrasana may be harmful to knees.

The pose has been linked to damage to the common fibular nerve resulting in foot drop, where dorsiflexion of the foot is compromised and the foot drags (the toe points) during walking.
