Knee Replacement

What is a total knee replacement?

Total knee replacement (also called total knee arthroplasty) is a surgical procedure that replaces a damaged or worn-out knee joint with artificial components to relieve pain and restore function.

Why would someone need a knee replacement?

It is usually recommended for people with:

• Severe osteoarthritis
• Rheumatoid arthritis
• Post-traumatic arthritis
• Significant knee deformity
• Chronic pain and mobility issues not relieved by other treatments

What are the signs that I might need a knee replacement?

• Persistent knee pain that limits daily activities
• Difficulty walking, climbing stairs, or standing
• Pain while resting or at night
• Stiffness or swelling that doesn’t improve with conservative treatment

How long does a knee replacement last?

Modern knee implants typically last 15–20 years or more. Their lifespan can be extended with proper care and activity modifications.

How do I prepare for knee replacement surgery?

Preparation may include:

• Medical evaluations and lab tests
• Discontinuing certain medications
• Strengthening exercises and physical therapy

What is the recovery time after total knee replacement?

Initial recovery typically takes 6 weeks, with full recovery and maximum benefits appearing after 6 to 12 months, depending on your health and rehabilitation progress.

Will I need physical therapy after surgery?

Yes. Physical therapy is essential for regaining knee strength, flexibility, and function. Therapy often starts the day after surgery.

Will I be able to walk after surgery?

Yes, most patients start walking (with assistance) within a day or two after surgery. Walking aids like walkers or crutches may be needed initially.

Are there activity restrictions after knee replacement?

High-impact activities (e.g., running, jumping, skiing) are generally discouraged. Low-impact exercises like golf, swimming, biking, and walking are encouraged.

What is the difference between total and partial knee replacement?

Total knee replacement involves resurfacing the entire knee joint. Partial knee replacement replaces only the damaged part of the knee and is typically an option for patients with damage limited to one compartment.

Will I go home the same day?

Some patients may go home the same day (outpatient surgery), but most stay in the hospital for 1–2 days. Discharge depends on mobility, pain control, and overall health.

What is the success rate of knee replacement surgery?

Over 90% of knee replacements provide lasting pain relief and improved mobility. Patient satisfaction is high, especially when recovery guidelines are followed closely.

What are the risks of knee replacement surgery?

Potential risks include:

• Infection
• Blood clots
• Implant loosening or wear
• Stiffness or limited motion
• Nerve or blood vessel injury
• Continued pain or instability
