A Total Joint Replacement is one of the most frequent procedures performed, with over 7 million done in the US alone. The two most common procedures are total replacements of the hip and knee but they all share the same underlying problem. The cartilage, where the two bones meet, is compromised from arthritis (osteo, rheumatoid, post-traumatic) and may need surgical intervention for long term functionality. Your surgeon will remove the cartilage surfaces and prepare the ends of each bone for the proper implant. Your surgeon will use either a cement or un-cemented (“press fit”) device when securing it down to bone, each has their own advantages but cement is most common. Most devices are comprised of two metal bone components and a plastic spacer which gives cushion when pressure is applied. The outcome of these procedures are tremendously successful and nearly all patients claim to be back to their active lifestyles with less pain.
