Hip joints are engaged in every step we make. When they hurt, it can really slow us down. After a thorough examination by our surgeons, non-operative or operative treatments may be recommended, depending on the condition.As our hip joint ages, or sometimes due to injury, hip replacement may be recommended. More than 168,000 total hip replacements are performed each year in the US. It is a highly successful procedure where surgeons replace the ball and socket with a prosthesis in order to relieve pain and restore mobility.
