Knee joint replacement surgery is a procedure that can significantly improve the quality of life for individuals suffering from chronic knee pain or limited mobility due to various conditions. It is a common yet highly effective treatment for those who have tried non-surgical methods and are still struggling to regain function and relieve pain. In this blog, we will take you through an informative guide on knee joint replacement, its benefits, types of surgeries, and the recovery process.
Synopsis
Importance of the Knee Joint
The knee joint is one of the largest and most crucial joints in the human body. It serves as a key link between the thigh and the lower leg, enabling essential movements such as walking, running, and jumping. The knee’s main function is to support body weight and allow fluid movement, which is vital for a variety of daily activities. A healthy knee joint ensures that an individual can perform routine tasks like walking, climbing stairs, sitting, standing, and even participating in sports. Any impairment in its functionality can significantly affect a person’s mobility and quality of life.
Common Knee Injuries and Conditions
Over time, the knee joint can face wear and tear due to injuries, diseases, and ageing, resulting in pain, stiffness, and limited movement. Some of the most common knee-related issues include:
-
Fractures: A break or crack in one of the bones that form the knee joint. These can happen due to accidents or falls and often require surgical intervention.
-
Dislocations: The displacement of the knee bones, which may require immediate medical attention and can lead to instability or injury to surrounding ligaments and tissues.
-
Arthritis: The most common cause of knee pain, particularly osteoarthritis, is where the cartilage wears down, causing bones to rub against each other. This leads to swelling, pain, and loss of function.
-
Ligament Injuries: Damage to ligaments like the ACL or PCL can severely affect knee stability, often requiring surgical correction if conservative treatments fail.
Types of Knee Joint Replacement
There are two main types of knee replacement surgeries: Total Knee Replacement (TKR) and Partial Knee Replacement (PKR). Your surgeon will determine the best option based on the extent of joint damage.
-
Total Knee Replacement (TKR): In this procedure, the entire knee joint is replaced, including the femur (thigh bone), tibia (shin bone), and patella (knee cap). TKR is typically recommended for patients who have severe arthritis or joint degeneration that affects the entire knee.
-
Partial Knee Replacement (PKR): Also known as unicompartmental knee replacement, this surgery replaces only the damaged part of the knee joint. PKR is suitable for patients with arthritis or damage in one compartment of the knee, preserving the rest of the joint.
Both surgeries aim to alleviate pain, restore function, and enhance the patient's mobility, but the choice of surgery depends on the patient’s condition and overall health.
The Knee Replacement Procedure: Step-by-Step
Knee replacement surgery is typically performed under general or regional anaesthesia. Here’s a general overview of the procedure:
-
Preparation: The patient is positioned on the operating table, and the surgeon marks the areas of the knee to be operated on.
-
Incision: A small incision is made over the knee to allow access to the joint. In some cases, minimally invasive techniques may be used to reduce the size of the incision.
-
Removal of Damaged Tissue: The damaged parts of the femur, tibia, and patella are removed, and any remaining healthy tissue is prepared to fit the prosthesis.
-
Implantation: The prosthetic components, which may be made of metal, plastic, or ceramic, are carefully fitted into place, creating a new joint.
-
Closing: The incision is closed using sutures or staples, and the knee is bandaged to minimize swelling.
The entire procedure typically takes around one to two hours, and patients are usually monitored in a recovery room for several hours post-surgery.

Post-operative Care and Recovery
Recovery from knee replacement surgery varies from person to person, but most patients begin to see improvements within a few days. The general recovery process includes:
-
Pain Management: Pain is controlled through medication and ice packs, ensuring comfort during the healing process.
-
Physical Therapy: A vital part of the recovery process, physical therapy helps improve mobility, strengthen muscles, and reduce stiffness. Most patients start therapy within 24 to 48 hours after surgery.
-
Monitoring: Follow-up visits with the surgeon are necessary to monitor progress, check for complications, and adjust the rehabilitation plan accordingly.
The full recovery process may take several months, but most people can return to normal activities within 6 to 12 weeks.

Benefits of Knee Replacement
Knee replacement surgery offers numerous benefits, especially for individuals suffering from debilitating knee pain. Some of the key advantages include:
-
Pain Relief: One of the most significant benefits is the relief from chronic pain caused by arthritis or joint damage.
-
Improved Mobility: Most patients experience a significant improvement in movement and flexibility, making everyday tasks much easier.
-
Enhanced Quality of Life: With pain reduced and mobility restored, many patients can resume activities they thought were no longer possible, like walking, swimming, or playing sports.
-
Long-Term Solution: Knee replacements have a high success rate, and the artificial joint can last up to 20 years with proper care and maintenance.

FAQ's
After full recovery, some patients are able to engage in low-impact activities like swimming or cycling. However, high-impact activities like running or jumping are not recommended, as they can place excessive stress on the new joint.
Full recovery can take between 6 to 12 months, though significant improvement in pain and mobility is usually seen within a few weeks.
As with any surgery, knee replacement carries risks like infection, blood clots, and complications with anaesthesia. However, these risks are minimal, especially when performed by experienced surgeons.
Yes, physical therapy is a crucial part of the recovery process. It helps improve joint function, strength, and flexibility, ensuring that you regain full mobility and reduce stiffness.
Swelling is common after knee replacement surgery, especially in the first few weeks. It can be reduced with elevation, compression, and ice packs. However, some swelling may persist for a few months as the knee heals.
