Hip joint osteoarthritis is among the most common joint disorders with 87,733 hip replacements recorded by the national joint registry in 2016. Research studies suggest that the incidence of lower back pain accompanying hip arthritis is in the range of 20-40% of cases.
Arthritic changes to the cartilage surface lining the head of the femur (thigh bone) and the acetabulum (joint socket within the pelvis) cause gradual thickening and shortening of the hip joint capsule (ligament like tissue encasing the joint). The resulting reduction in flexibility at the hip joint impacts upon surrounding muscle tissue often causing shortening and decline in strength and control, thus accelerating the rate of damage to the cartilage surfaces.
