What is Knee Replacement?

Knee replacement, also known as knee arthroplasty, is a surgical procedure designed to replace a damaged, worn-out, or diseased knee joint with an artificial joint, called a prosthesis.

Types of Knee Replacement

There are different types of knee replacement surgeries based on the condition of your knee.

Total Knee Replacement (TKR)

In this procedure, the entire knee joint is replaced with a prosthesis. It’s the most common type of knee replacement surgery, providing relief for people with widespread damage.

Partial Knee Replacement (PKR)

Rehabilitation and Physical Therapy After Knee Replacement

Importance of Physical Therapy

Rehabilitation is crucial to regain strength and flexibility in the knee.

Types of Exercises for Recovery

These may include walking, knee bends, and strengthening exercises to gradually increase mobility.

Expected Timeline for Rehabilitation

Most patients begin physical therapy the day after surgery and continue for several weeks or months, depending on progress.

  • Pain Relief: The biggest benefit is relief from chronic knee pain.
  • Improved Mobility and Function: Patients regain the ability to walk, climb stairs, and enjoy activities they previously avoided.
  • Enhanced Quality of Life: With increased independence, knee replacement often results in a more active lifestyle.

Short-Term vs Long-Term Recovery

While most patients see significant improvement in 3 months, full recovery can take up to a year.

Returning to Daily Activities

By 6-8 weeks, most people can resume normal activities, though strenuous tasks may take longer.

When to Resume Work and Hobbies

Depending on your job and hobbies, it may take 6-12 weeks before returning to work or physical activities.

Life After Knee Replacement Surgery

Long-Term Care of Your Knee

Regular check-ups and exercises are essential for the longevity of the prosthesis.

Activities to Avoid

High-impact sports like running should be avoided, but low-impact activities like swimming or cycling are encouraged.
