What is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, is a procedure in which damaged portions of the knee joint are replaced with artificial implants. The surgery is designed to relieve pain, improve movement, and restore function in patients with severely damaged knee joints. Modern knee replacement procedures have shown excellent outcomes in reducing pain and improving mobility for patients suffering from advanced arthritis and joint degeneration.

When is Knee Replacement Surgery Needed?
Not every patient with knee pain requires surgery. However, knee replacement may be recommended when joint damage becomes severe and significantly impacts daily life.
You may be a candidate for knee replacement surgery if you experience:
- Severe knee pain during walking or standing
- Persistent stiffness in the knee joint
- Difficulty climbing stairs
- Knee deformity or bowing
- Swelling that does not improve
- Limited range of motion
- Poor response to medications and physiotherapy
- Advanced osteoarthritis or rheumatoid arthritis
Early consultation with an orthopedic specialist can help determine whether surgery is the most appropriate treatment option.
Common Causes of Severe Knee Damage
Several conditions can lead to progressive knee joint deterioration.
The most common causes include:
Osteoarthritis
Osteoarthritis is the leading cause of knee replacement surgery. It occurs when the cartilage protecting the knee joint gradually wears away, causing pain, stiffness, and reduced mobility.
Rheumatoid Arthritis
This autoimmune condition causes chronic inflammation that can damage the knee joint over time.
Post-Traumatic Arthritis
Previous injuries, fractures, or ligament damage may result in long-term joint degeneration.
Severe Joint Injury
Sports injuries and accidents can sometimes lead to irreversible knee damage requiring surgical intervention.
Age-Related Joint Degeneration
Natural wear and tear over time can affect the knee’s ability to function normally.
Many patients delay treatment for years despite worsening symptoms.
You should seek orthopedic evaluation if you experience:
- Chronic knee pain
- Persistent swelling
- Difficulty walking
- Pain during daily activities
- Joint stiffness after resting
- Knee instability
- Reduced mobility
- Difficulty sitting or standing
Timely treatment can help prevent further joint deterioration and improve long-term outcomes.
How is Knee Replacement Evaluated?
At Hayat Hospital, a thorough orthopedic assessment is performed before recommending surgery.
Evaluation may include:
- Detailed medical history
- Physical examination
- Standing knee X-rays
- Blood investigations
- Joint alignment assessment
- Functional mobility evaluation
- Additional imaging when necessary
These investigations help determine the severity of joint damage and identify the most suitable treatment plan.
Types of Knee Replacement Surgery
Depending on the extent of damage, different surgical approaches may be recommended.
Total Knee Replacement (TKR)
The entire damaged knee joint is replaced with artificial components. This is the most commonly performed procedure for advanced arthritis.
Partial Knee Replacement
Only the damaged portion of the knee is replaced while preserving healthy tissue.
Revision Knee Replacement
This procedure is performed when a previous knee replacement requires correction or replacement. Your orthopedic surgeon will recommend the most appropriate procedure based on your condition and lifestyle requirements.
