Chronic knee pain can significantly affect your mobility, independence, and quality of life. When medications, physiotherapy, and lifestyle changes no longer provide relief, total knee replacement surgery offers an effective and long-term solution. With advancements in orthopaedic care, modern procedures are safer, more precise, and designed to help patients return to an active lifestyle.
What is Total Knee Replacement?
Total Knee Replacement (TKR), also known as knee arthroplasty, is a surgical procedure in which damaged or worn-out parts of the knee joint are replaced with artificial components made of metal and high-grade plastic. These implants are designed to replicate the natural movement of the knee, reduce pain, and restore function.
This procedure is commonly recommended for patients suffering from severe osteoarthritis, rheumatoid arthritis, or knee injuries that have led to joint degeneration.

Symptoms
You may need a total knee replacement if you experience:
- Persistent knee pain that limits daily activities
- Difficulty walking, climbing stairs, or standing for long periods
- Swelling and stiffness in the knee joint
- Reduced range of motion
- Knee deformity (bowing in or out)
- Pain that does not improve with medication or therapy

If these symptoms affect your quality of life, it is important to consult an orthopaedic specialist.
Treatment
Before recommending surgery, doctors usually try conservative treatments such as medications, physiotherapy, weight management, and injections. If these options fail to provide relief, total knee replacement may be advised.
The procedure involves removing damaged cartilage and bone from the knee joint and replacing them with artificial implants. Advanced techniques like minimally invasive surgery and robotic-assisted knee replacement improve precision and reduce recovery time.
The surgery typically lasts 1–2 hours and is performed under spinal or general anesthesia. Most patients experience significant pain relief and improved mobility after the procedure.
Recovery
Recovery plays a crucial role in the success of knee replacement surgery. Patients are usually encouraged to start moving the knee within a day after surgery.
Physiotherapy is essential to regain strength, flexibility, and mobility. Most patients can walk with support within a few days and gradually return to normal activities over 4–6 weeks. Full recovery may take a few months.
Following post-operative instructions, maintaining a healthy weight, and staying active help ensure long-term success of the knee implant.
