Joint replacement

Joint replacement is a surgical procedure in which parts of an arthritic or damaged joint are removed and replaced with a metal, plastic or ceramic device called a prosthesis. The prosthesis is designed to replicate the movement of a normal, healthy joint.

Types of Joint Replacement

There are several types of joint replacement surgeries, including:

• Hip replacement
• Knee replacement
• Shoulder replacement
• Elbow replacement
• Ankle replacement
• Wrist replacement

Indications for Joint Replacement

Joint replacement surgery is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. The common indications include:

• Osteoarthritis
• Rheumatoid arthritis
• Post-traumatic arthritis
• Avascular necrosis
• Bone dysplasias

Procedure

The procedure involves the removal of the damaged cartilage and bone and then positioning new metal or plastic joint surfaces to restore the function of the joint.

Risks and Complications

Like any surgery, joint replacement surgery has risks. Complications can include:

• Infection
• Blood clots
• Nerve injury
• Prosthesis failure
• Pain

Recovery

Recovery from joint replacement surgery can take several weeks to months and involves physical therapy to help regain strength and mobility in the joint.
