Arthroscopic surgery, also known as arthroscopy, is a surgical procedure to visualize, diagnose, and treat problems inside a joint using a specialized instrument known as an arthroscope.

Your shoulder joint is a ball and socket joint made up of the upper arm bone, the shoulder blade and the collarbone. The head of the upper arm bone fits into the socket of the shoulder joint known as the glenoid cavity.

Femoroacetabular impingement (FAI) is a condition in which the bones of the hip joint grow abnormally and do not fit together properly. This leads to restricted hip movement and increased friction.
