Our hip joint has two parts – a ball (part of thigh bone-femur) and a cup ( part of the hip bone). When the ball moves inside the cup, there is movement in the hip joint. THR is a surgical procedure when part of the femoral head (ball) and damaged part of the cup is removed and replaced by an artificial one.
We perform THR through the posterolateral approach, and most of the time we perform it by a minimally invasive surgery (MIS total hip replacement).
