Get advanced Unilateral Knee Replacement for pain-free movement and lasting joint health
Unilateral Knee Replacement
Unilateral Knee Replacement (UKR), also known as partial knee replacement, is a surgical procedure in which only one side of the knee joint is replaced. Unlike Total Knee Replacement (TKR), where the entire knee joint is replaced, UKR focuses on replacing only the damaged or worn-out portion of the knee. This procedure is often performed on patients suffering from osteoarthritis, rheumatoid arthritis, or knee injuries that have affected only one part of the knee.
In Unilateral Knee Replacement, the surgeon removes the damaged cartilage and bone from one part of the knee joint (typically the inner or medial compartment) and replaces it with a prosthetic component. The healthy parts of the knee, including the other compartments, are left intact. The goal of the surgery is to alleviate pain, improve mobility, and restore the function of the knee without the need for a full knee replacement.
UKR offers several advantages over TKR, such as a quicker recovery time, a smaller incision, less blood loss, and the preservation of more natural knee tissue. This procedure is especially suitable for older patients with localized knee damage or those who want to preserve as much of their knee joint as possible.
Early Detection Saves Lives
Early detection and treatment are crucial for improving the chances of survival. If you notice any concerning symptoms, consult a healthcare provider immediately.
Unilateral Knee Replacement – Signs and Symptoms

Unilateral Knee Replacement – Risk Factors
Smoking
Smoking is one of the leading causes of bladder cancer. Chemicals in tobacco smoke can damage the lining of the bladder, increasing the risk.
Gender
Men are at a higher risk of developing bladder cancer than women.
Chronic Bladder Infections or Inflammation
Conditions such as bladder infections and long-term bladder inflammation can increase the risk.
Exposure to Chemicals
Prolonged exposure to certain chemicals, especially those used in the dye industry, rubber production, and chemical manufacturing, increases the risk.
Age
As people age, the cartilage in the knee joint naturally wears down, making older adults more susceptible to knee arthritis and joint damage.
Osteoarthritis
This is the most common cause of knee damage requiring UKR. Osteoarthritis causes the cartilage in the knee joint to break down, leading to pain, stiffness, and reduced mobility.
Rheumatoid Arthritis
An autoimmune condition that can affect the knee joint, causing inflammation, joint damage, and pain.
Previous Knee Injuries
Past knee injuries, such as fractures, ligament tears, or meniscal damage, can lead to joint degeneration and increase the need for UKR.
Obesity
Excess weight puts additional pressure on the knee joints, which can accelerate the wear and tear of cartilage, leading to knee arthritis.
Genetics
A family history of knee problems or joint disorders can increase the risk of developing knee issues that may require surgery.
Sedentary Lifestyle
Lack of exercise can lead to muscle weakness and poor joint stability, increasing the strain on the knee.

Proper nutrition plays an essential role in managing knee health and supporting recovery after Unilateral Knee Replacement surgery:
- Calcium and Vitamin D: These nutrients are essential for maintaining strong bones. Foods like dairy products, leafy greens, and fortified cereals are excellent sources of calcium, while Vitamin D can be obtained from sunlight and foods like fatty fish and fortified foods
- Protein-Rich Foods: Protein is crucial for healing after surgery and maintaining muscle mass. Lean meats, fish, eggs, legumes, and dairy products provide high-quality protein
- Anti-Inflammatory Foods: Incorporating anti-inflammatory foods like salmon, walnuts, flaxseeds, ginger, and turmeric into your diet can help reduce inflammation in the knee joint and speed up recovery.
- Omega-3 Fatty Acids: Found in fatty fish like salmon, flaxseeds, and walnuts, omega-3s help reduce inflammation and support joint health
- Hydration: Staying hydrated supports overall health, including joint lubrication and circulation, which is important for post-surgery healing
- Weight Management: Maintaining a healthy weight reduces stress on the knee joint, which can help prevent further damage and support the healing process after surgery.

Frequently Asked Questions
Recovery from Unilateral Knee Replacement typically takes about 6 weeks to 3 months. Most patients can begin walking with assistance within a few days, but full recovery, including regaining strength and mobility, may take up to 6 months. Physical therapy is essential for restoring knee function.v
As with any surgery, Unilateral Knee Replacement carries risks such as infection, blood clots, nerve damage, or knee stiffness. However, these risks can be minimized by following the surgeon’s advice and receiving proper post-surgery care. It’s important to attend follow-up appointments to monitor progress.
A Unilateral Knee Replacement can last anywhere from 15 to 20 years, depending on factors like age, activity level, and the materials used for the prosthesis. Regular check-ups are essential to monitor the condition of the knee implant and ensure it remains functional.
