Hip Osteoarthritis  - Hip and groin pain

Hip joints are one of the largest, deepest and most stable joints in the body. They are also one of the most mechanically challenged. They are required to provide the highest level of stability with functional mobility.

The hip acts at the linchpin receiving downwards loads from the trunk and transferring forces upwards from the ground to the pelvis and trunk. They are frequently required to operate at extreme ranges of movement and withstand high forces (x3 body weight when running) and rapid rates of loading, all of which has its consequences.

The hip joint comprises different tissues such as bony, muscular and cartilage all controlled by the nervous system. Throughout life, these tissues are subject to loading and are remodel to replace old with new to maintain tissue integrity and function. This life cycle continues as a consequence of the demands made through our daily and lifelong activities of repetitive loading. Trauma associated with falls, contact sports or both (e.g. rugby and football) places additional demands on joint function and recovery.

Eventually, as for all mechanical joints the contact leads to surface erosion often termed ‘wear and tear’ and modifies joint shape. This is often associated with a reduction in range of hip movement; hip strength can often reduce and result in hip / groin pain.

This degenerative hip condition (hip osteoarthritis) does not come alone. Bony changes are also accompanied with changes in muscular function (muscular length, strength, and stability control), placing additional demands on the hip from above and below.
