Normal sitting causes hip degeneration because there is a pressure point in the upper hip bowl. The seat pushes the femur up and the body sinks down because of gravity. In saddle sitting the seat pushes the femur out and releases the pressure on the cartilage in the hip joint. This increases the circulation and improves the cartilage/ joint health and prevents the arthritis.

This picture shows the enormous density of the blood circulation system in the pelvic area. Pelvic circulation is very important to the healthy metabolism, but it is often disturbed. Notice dense vessel network in the pelvic joint areas.
