Arthroplasty: Joint Replacement

What is Arthroplasty?

Arthroplasty, commonly known as joint replacement surgery, is a procedure in which a damaged joint is replaced with artificial components. These components are designed to restore movement and reduce pain caused by joint disease or injury. Arthroplasty is most often performed on the hip, knee, shoulder, and ankle.

Why arthroplasty may be recommended

Arthroplasty may be considered for patients who have:

• Severe joint arthritis
• Chronic joint pain affecting daily life
• Stiffness or loss of joint function
• Joint damage that has not improved with nonsurgical care

The goal is to improve comfort, mobility, and quality of life.

How the procedure works

During arthroplasty:

• An incision is made to access the joint.
• Damaged bone and cartilage are removed.
• Artificial joint components are implanted to replace the damaged surfaces.
• The joint is tested for stability and movement before closure.

The specific technique varies based on the joint and implant type.

Potential benefits

Arthroplasty may:

• Significantly reduce joint pain
• Improve range of motion
• Enhance mobility and function
• Allow return to daily activities

Most patients experience gradual improvement over time.

Recovery — what to expect

Recovery depends on the joint replaced and individual health. Many patients:

• Begin moving the joint soon after surgery
• Participate in physical therapy for pain management and functional retraining
• Engage in strength, flexibility, and conditioning training
• Follow a specific hip phase-by-phase protocol depending on the surgical approach
• Use an assistive device if necessary
• Gradually return to normal activities over weeks to months

Your care team will provide detailed rehabilitation and follow-up guidance.

Risks and possible complications

Possible risks include:

• Infection
• Blood clots
• Implant wear or loosening over time
• Stiffness or persistent pain
• Nerve or blood vessel injury (rare)

Your surgeon will discuss risks and expectations before surgery.
