Degenerative and rheumatoid arthritis of the hip joint are very common and are characterized by a degradation, or wearing away, of the bearing surfaces on both the femoral head (the ‘ball’ of the hip joint) and the acetabulum (the ‘socket’ of the hip joint). Arthritis typically causes pain, often felt in the groin, which tends to be worse with weight-bearing and changing positions. It can also cause stiffness and be severe enough to greatly limit one’s activity, making it hard or impossible to get through daily tasks, work, or recreational activities. Losing weight, taking medications, doing gentle exercises to increase strength and flexibilty, and using support like a cane can help, but the underlying processes are irreversible. For people who find the pain and limitations intolerable or unacceptable, hip replacment operations are often a good solution. For more information on hip arthritis, please click here.
