Can the joint capsule be pierced?

Answer 1

Not for the sake of body piercing, only in the event of surgical procedures should the joint capsule be pierced, then it is balanced with saline solution to prevent damage to the joint. The capsule contains fluid that allows the joint to move freely without friction damage by direct contact of the ball and socket. Piercing that capsule will damage the joint an repair will be difficult if not impossible once damage is done.
