Can knee degenerative joint disease which has resulted in increased leg “bowing” lead to hip problems such as increased wear on the hip joint?

Degenerative joint disease, otherwise known as osteoarthritis, is the term used to describe the mechanical degradation of joints. Osteoarthritis can affect any joint of the body but they commonly affect weight bearing joints such as the hips, knees, and spine. Osteoarthritis is believed to be caused by a mechanical process or misalignment of bones that causes increased wear and tear of the joints. Therefore, anything affecting the proper alignment of bones, such as your described osteoarthritis of the knee, can affect mechanically relevant joints, such as the hip.
