MCP Joint Arthroplasty and Realignment
Metacarpophalangeal (MCP) joint arthroplasty is most often performed to treat rheumatoid arthritis within the fingers. Patients suffering from severe pain, swelling and stiffness that affects their ability to perform everyday activities may benefit from an arthroplasty procedure. Rheumatoid arthritis can also cause physical deformities that make grasping and pinching nearly impossible.
Arthroplasty has been used to successfully treat MCP joint arthritis for many years, and thus has a very high long term success rate. Patients will likely need to undergo physical therapy after surgery in order to restore strength and function to the fingers. The replacement joint is usually made of silicone, which does erode over long periods of time and in rare cases may need to be replaced.
