What is Knee Replacement?

Knee replacement, also called knee arthroplasty is a surgical procedure that replaces a damaged knee with a plastic or metal implant. The surgery is recommended to people who have been suffering from severe arthritis or have suffered a major knee injury. 

There are several types of arthritis that can affect the joints of the knee. Some of the most common ones include osteoarthritis, rheumatoid arthritis, and traumatic arthritis. Osteoarthritis is a degenerative joint disease that affects middle-aged or older people. The condition can cause the breakdown of the cartilage in joints and makes the knee joint weaker. Rheumatoid arthritis, on the other hand, leads to inflammation of the synovial membranes in joints and can cause excessive fluid buildup, which leads to stiffness and pain. Lastly, traumatic arthritis is caused due to a major injury to the knee and can severely damage the knee cartilage, which may give rise to the need for a joint replacement. 

Before recommending knee replacement surgery, your doctor will try to use conservative methods for your treatments. In case such methods failed to show effect, surgical treatments will be considered. To determine if you were a viable candidate for knee replacement surgery, some physical tests and scans will be done. Moreover, the surgical technique would also depend upon your body weight, activity, size, and shape of the knee, and overall health.

Types of disease

Total Knee Replacement

Unicompartmental or Partial Knee Replacement


Treatment for pain and discomfort in the knees will begin with conservative methods that include physiotherapy, anti-inflammatory drugs, and cortisone injections. If you have not seen any effect even after a considerable amount of time and are still experiencing pain while doing simple activities or when you’re at rest, you may require knee replacement surgery. Other symptoms may include stiffness, inflammation, and swelling of the joint.

Potential risks and complications associated with knee replacement

Minimally invasive knee replacement surgeries have a success rate of 90 to 95 percent, and the implant stays durable for 10 to 15 years in suitable conditions. However, as knee replacement surgery is a major procedure, there are some potential risks and complications associated with it. Possible risks may include the following. 

  • Deep vein thrombosis
  • Pulmonary embolism
  • Infections
  • A fracture after or during the surgery
  • Bleeding in the joint during or post-surgery
  • Instability of the knee cap leading to dislocation
  • Nerve damage leading to numbness or weakness 
  • Ligament or artery damage
  • Pain and stiffness post-surgery
  • Allergic reaction to bone cement
  • Excess bone formation around the knee implant, leading to loss of movement
  • Excess scar tissue buildup
  • Wearing down of implant

The patient should be on the lookout for signs of complications after the surgery. Swelling, bleeding, and redness around the site of operation, and fever can be signs of an infection.  Tenderness, redness, and swelling below the knee, or in the calf or foot may indicate a blood clot in the leg or deep vein thrombosis, while shortness of breath and pain in the chest after surgery can be indicative of pulmonary embolism or blood clot in the lungs.

If the patient suspects the presence of any of the above-given complications, immediate medical attention should be sought. 

  • Myths and facts about knee replacement surgery

    Myth: Knee replacement surgeries are not very successful.

    Fact: Knee replacement surgery is an effective treatment option for people whose knees have been worn out because of an injury or disease. The success rate of knee replacement surgery is as high as 95% for most patients and allows people to go back to their routine lives after they are fully recovered.

    Fact: It is a common misconception that bending and straightening of knees become difficult after a knee replacement surgery, but this is false.

In most cases, the range of motion is restored back to normal after recovery.

    Fact: This depends upon the quality of surgery and force operative care. more people than go back to routine within a few weeks after the surgery


    Myth: Knee replacement surgery is very painful.

The advanced surgical techniques ensure that the patient experiences minimum pain and remains comfortable during the operative and postoperative periods. 


    Myth: Magnetic therapy, ozone treatment, massage beds, laser therapy, oiling, acupressure, and braces can cure knee pain effectively and permanently. 

    Fact: While there are many non-surgical conservative treatment methods available for managing knee pain, none of them are backed up with strong, scientific research and are not capable of providing permanent relief from pain, stiffness, discomfort, and inflammation in the knee joints. These treatments can provide temporary relief, but will not cure the problem. 


    Myth: One cannot drive after undergoing knee replacement surgery. 

    Fact: On the contrary, driving becomes much easier after knee replacement surgery for people who have pain and stiffness in their joints. Within six to eight weeks of the surgery, the patient can start driving again, but it is always best to consult your doctor before you resume driving. 


    Myth: Knee replacement surgery cannot be done once you pass the age of 60 years. 

    Fact: Age is not necessarily a deciding factor in a knee replacement surgery.
