What Is A MP Joint Arthroplasty?

MP joint arthroplasty, also known as metacarpophalangeal joint arthroplasty, is a surgical procedure performed to replace the damaged or diseased metacarpophalangeal (MP) joint in the hand. The MP joint is the joint located between the metacarpal bone (the long bone of the hand) and the proximal phalanx (the first bone of the finger).


  • MP joint arthroplasty is indicated when the MP joint is severely damaged or affected by conditions such as arthritis, traumatic injury, or deformities.
  • The procedure is considered for patients who experience pain, stiffness, loss of motion, and functional impairment in the affected MP joint that does not respond to conservative treatments.


  • The surgery is usually performed under regional or general anesthesia, depending on the patient’s condition and the surgical technique used.
  • During the procedure, the surgeon makes an incision over the affected MP joint to access the joint and surrounding structures.
  • The damaged cartilage and bone at the joint surfaces are carefully removed to prepare the joint for the implant.
  • An artificial joint implant, made of metal, plastic, or other materials, is then inserted into the prepared joint space.
  • The implant is designed to mimic the natural movement of the MP joint, allowing for improved hand function and reduced pain.

Types of MP Joint Arthroplasty:

There are different types of MP joint arthroplasty, including:

    • Silicone implant arthroplasty: In this approach, a silicone implant is used to replace the damaged joint surfaces.
    • PyroCarbon implant arthroplasty: This method involves using a pyrocarbon implant, which is a lightweight and durable material designed to replicate the natural joint movement.


  • The recovery time after MP joint arthroplasty varies depending on the individual’s healing capacity and the surgical technique used.
  • Physical therapy or hand rehabilitation may be recommended to improve hand strength, flexibility, and function.
  • The patient may need to wear a splint or protective brace for a period to support the hand during the initial healing phase.


  • The success of MP joint arthroplasty depends on various factors, including the patient’s overall health, the severity of joint damage, and their commitment to postoperative care and rehabilitation.
  • In many cases, MP joint arthroplasty can significantly reduce pain, improve hand function, and enhance the patient’s quality of life.

MP joint arthroplasty is a specialized surgical procedure that requires the expertise of a skilled hand surgeon experienced in performing joint replacement surgeries. Patients considering MP joint arthroplasty should discuss the benefits, risks, and potential complications with their healthcare provider before proceeding with the surgery. Proper patient selection and adherence to postoperative care are essential for achieving successful outcomes.
