There are several types of joint replacements that are commonly performed. Board certified surgeons can perform hip replacements, knee replacements, and shoulder replacements. These are the most common types of replacements but finger, toe and elbow joints can also be replaced. Most of the time, a joint is replaced to increase a person’s mobility and improve function. What type of joint replacement is used will depend largely on which type of joint is being replaced; and the types of movements that are required from the joint. There are several different arthroplastic replacements that are available.
