This document describes the anatomy of the hip joint, including the femur, femoral head, femoral neck, pelvis, acetabulum, acetabular labrum, and femoral ligaments. It then provides overviews of hip arthroscopy and total hip replacement procedures. Hip arthroscopy involves making small incisions to examine and repair damaged structures like the labrum or cartilage using tools inserted through the incisions. Total hip replacement removes damaged bone and implants a metal shell in the socket and stem in the femur, joining them with a ball to form an artificial joint.
