What is Total Knee Replacement Surgery?

How do I know if I need Knee Replacement Surgery?

How do I know if I need Knee Replacement Surgery?
Knee replacement is considered a major surgery and there are many factors to consider first before making a decision. It is a question that cannot be answered easily. Rather, it requires you and your orthopaedic surgeon to sit down and ponder through all the possible options available to you before deciding on it. 

Oral medications do not work
Your doctor will usually prescribe non-steroidal anti-inflammatory drugs such as Ibuprofen or Naproxen Sodium to help make the pain more bearable and reduce inflammation. However, these drugs are only able to help counteract the pain to a certain extent and they do not treat your knee condition. You should not be consuming drugs for the rest of your life as they might harm your body. After a certain time span and it has no effect, surgery will be required.

Physical therapy has little effect
Oral medication will often be accompanied by physical therapy sessions. Physical therapy helps to build up the muscles around the knee, strengthening them so that they can better support your knee. It also helps to make the knee joint much more flexible and restore joint mobility. However, when this still does not help, surgery will be required.

Daily activities are limited
When simple daily activities are severely limited due to knee pain, surgery may be the only option left. You do not want your quality of life to be affected by your knee and there is always the option of knee replacement surgery. Some patients may not even be able to sleep as the pain will keep them up throughout the night. For others, simple actions such as walking may also be a chore.

You wish to engage in competitive sports
This is the most common reason for total knee replacement surgery. Athletes who wish to continue engaging in competitive sports will definitely require surgery to replace the damaged joints with artificial bio-materials in order to regain near full strength and mobility.

There are many reasons for one to undergo knee replacement surgery. Knee replacement surgery is a major surgery and requires one to consider many factors before deciding on it. It does not come cheap and for most patients, physical therapy and medication will usually suffice. If you are seeking a return to sports, knee surgery may be the only viable option for you.

A total knee replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material. In Singapore, the procedure is also referred to as total knee arthroplasty so the two terms are interchangeable.

The knee is a hinge joint which provides motion at the point where the thigh meets the lower leg. The thigh bone abuts the large bone of the lower leg at the knee joint. During a total knee replacement, the end of the femur bone is removed and replaced with a metal shell.

If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down.

If medications, changing your activity level, and using walking supports are no longer helpful, you may want to consider total knee replacement surgery. By resurfacing the damaged and worn surfaces of the knee can relieve pain, correct leg deformity and help resume normal activities.

One of the most important orthopaedic surgical advances of the twentieth century, knee replacement was first performed in 1968. Improvements in surgical materials and techniques since then have greatly increased its effectiveness.

OSTEOARTHRITIS –  The most common cause of knee pain is degenerative osteoarthritis. Women are more prone to the disease. It is characterized by mild to debilitating pain.

Anterior Cruciate Ligament Injury
ACL Torn

  • Popping Sound at the time of injury
  • Knee swelling within 6 hours of injury
  • Pain especially when you try to put weight on the injured leg.

LIGAMENT INJURIES – Ligament injuries in the knee; such as an anterior cruciate ligament (ACL) are dreaded by professional and amateur athletes alike. They can be painful and debilitating. They can even permanently change your lifestyle.

Meniscus Tear

  • Sharp pain usually on the inside or outside the knee
  • Stiffness and Swelling
  • Clicking Sound
  • Twisting or squatting cause increasing pain
  • Knee gets stuck in a certain position that needs to wiggled to get it back into place.

MENISCAL TEAR – The meniscus is a small “c” shaped cartilage that acts as a cushion in the knee joint. They sit between the femur and the tibia bone, one on the outside and one on the inside of the knee.

Patellar (Jumper's Knee)

  • Unable to straighten knee by yourself.
  • Unable to perform a straight leg raise.
  • Swelling of knee and a papable defect at the location of the tear.

CONDROMALACIA PATELLA – Chondromalacia patella is a common cause of kneecap pain or anterior knee pain. Often called “Runner’s Knee,” this condition often affects young, otherwise healthy athletes.

Some other conditions of Knee Pain:

  • OSGOOD-SCHALLATER DISEASE – Osgood-Schlatter disease is a disorder of the lower front of the knee where the large tendon under the kneecap (patellar tendon) attaches to the bone of the leg below.
  • OSTEOCHONDRITIS DISSECANS – Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone beneath it, comes loose from the end of a bone.
  • GOUT – Gout is a rheumatoid form of arthritis that causes the inflammation, joint pain and swelling especially in the toe, knee and ankle, also reducing their mobility.
  • SHIN SPLINT – Shin splints are a member of a group of injuries called “overuse injuries.” Shin splints occur most commonly in runners or aggressive walkers
  • PATELLAR TENDONITIS – Patellar tendinitis is a common overuse injury. It occurs when repeated stress is placed on the patellar tendon. The stress results in tiny tears in the tendon, which the body attempts to repair.
  • DISLOCATING KNEECAPS – Kneecap dislocation occurs when the triangle-shaped bone covering the knee (patella) moves or slides out of place. The problem usually occurs toward the outside of the leg.
  • BAKER’S CYST – A Baker cyst is swelling caused by fluid from the knee joint protruding to the back of the knee. The back of the knee is also referred to as the popliteal area of the knee.

    BURSITIS – A bursa is a closed fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body.

  • PLICA SYNDROME – Often called “synovial plica syndrome,” this is a condition that is the result of a remnant of fetal tissue in the knee. The synovial plica are membranes that separate the knee into compartments during fetal development.

What Doctors do to treat your knee pain?


Physical therapy. Strengthening the muscles around your knee will make it more stable. Training is likely to focus on the muscles on the front of your thigh (quadriceps) and the muscles in the back of your thigh (hamstrings). Exercises to improve your balance are also important.

Orthotics and bracing. Arch supports, sometimes with wedges on the inner or outer aspect of the heel, can help to shift pressure away from the side of the knee most affected by osteoarthritis. Different types of braces may help protect and support the knee joint.


Corticosteroids. Injections of a corticosteroid drug into your knee joint may help reduce the symptoms of an arthritis flare and provide pain relief that lasts a few months. The injections aren’t effective in all cases. There is a small risk of infection.

Hyaluronic acid. This thick fluid is normally found in healthy joints, and injecting it into damaged ones may ease pain and provide lubrication. Experts aren’t quite sure how hyaluronic acid works, but it may reduce inflammation. Relief from a series of shots may last as long as six months to a year.


Arthroscopy surgery. Repair your joint damage using a fiber-optic camera and long, narrow tools inserted through just a few small incisions around your knee. Arthroscopy may be used to remove loose bodies from your knee joint, repair torn or damaged cartilage and reconstruct torn ligaments.

Partial knee replacement surgery.  Replaces only the most damaged portion of your knee with parts made of metal and plastic. 

Total knee replacement. In this procedure, your surgeon cuts away damaged bone and cartilage from your thighbone, shinbone and kneecap, and replaces it with an artificial joint made of metal alloys, high-grade plastics and polymers.
