What is Total Knee Replacement?

Total Knee Replacement, medically known as arthroplasty, is a procedure undertaken to replace a knee joint that has been damaged, typically due to osteoarthritis, rheumatoid arthritis, or traumatic injury. This surgery is essential for patients experiencing severe pain, stiffness, and a significant reduction in mobility and quality of life.
The procedure involves surgically removing the damaged joint surfaces and replacing them with artificial components, known as prostheses. These prostheses are designed to mimic the function of a healthy knee, aiming to restore mobility and alleviate pain.

What are the types of Orthopaedic Knee Surgery?

Knee revitalization surgeries are categorized based on the extent of the knee joint involved. The four primary types are

  1. Total knee replacement (TKR)
  2. Partial knee replacement (PKR)
  3. Revision Knee Replacement
  4. Robotic knee replacement

Total knee replacement (TKR)

Total Knee Replacement (TKR) involves replacing the knee’s damaged cartilage and bone with a prosthesis, primarily focusing on the femur and tibia, and occasionally the patella. This predominant form of joint replacement surgery aims to restore joint functionality, often eliminating the need for future operations.

When is TKR Needed?

Total Knee Replacement is recommended for severe, multi-compartmental arthritis causing significant pain and mobility issues unrelieved by other treatments.

Partial knee replacement (PKR)

Partial Knee Replacement (PKR) involves replacing bone ends on just one side of the knee, offering a less invasive alternative to TKR with quicker recovery, suitable for unilateral knee damage.

When is PKR Needed?

Partial Knee Replacement is advised for patients with osteoarthritis limited to one knee compartment, particularly when non-surgical treatments prove insufficient and knee alignment is mostly preserved.

Revision Knee Replacement

Revision Knee Replacement, a sophisticated procedure, addresses failed, loosened, or infected knee prostheses, demanding intricate techniques and specialized planning due to complexities like bone loss and scar tissue.

When is Revision Surgery Needed?

Revision Knee Replacement is required for failed previous surgeries due to wear, infection, loosening, or persistent post-operative pain.

Robotic Knee Replacement

Robotic Knee Replacement utilizes advanced robotics for heightened precision and accuracy in surgery, enabling pre-planned, 3D model-assisted procedures that enhance implant positioning and potentially improve post-operative knee movement and prosthesis longevity.

When is Robotic Surgery Needed?

Robotic Knee Replacement, suitable for both partial and total procedures, provides superior precision in implant placement, crucial for surgeries demanding exact alignment and positioning.

Type of Surgery Description When is it Needed? Differences and Requirements
Total Knee Replacement (TKR) Replaces all damaged cartilage and bone with a prosthesis. Severe arthritis affecting multiple knee compartments, significant pain and mobility issues. More extensive surgery, longer recovery, suitable for advanced degeneration.
Partial Knee Replacement (PKR) Replaces the ends of bones on one side of the knee. Osteoarthritis confined to a single compartment, no relief from non-surgical treatments, intact knee alignment. Less invasive, quicker recovery, not suitable for extensive arthritis or deformity.
Revision Knee Replacement Replaces or repairs a failed, loose, or infected implant. Previous knee replacement failure due to wear, infection, or loosening, persistent pain after initial surgery. More complex, needs specialized implants and techniques, and requires surgeon expertise.
Robotic Knee Replacement Uses robotic systems for enhanced precision and accuracy. Partial or total knee replacement is the crucial need for accurate implant placement. Advanced technology, specialized equipment and surgeon training, potentially better outcomes.

Some other alternatives are:

  • Arthroscopy 
  • Microfracture
  • Osteotomy 
  • Bilateral Knee Replacement
  • Revision Knee Replacement
  • Robotic-Assisted Knee Replacement

Use the Knee Pain Location Chart to identify the cause of your knee pain and its type.

Which type of knee Surgery is right for you?

Every type of orthopaedic surgery has its risks and benefits. This decision of option any surgery depends on the extent of your knee damage. If you have damage to all three compartments of your knee joint, a TKR is likely the best option. If only one side of your knee is damaged then Partial knee replacement (PKR) will work.
The following factors also play a significant role in your decision:

  1. Your age
  2. Your activity level
  3. Your overall health

The goal of surgery is to improve your quality of life. So, do not make any decisions on your own. Find knee replacement surgery options in Singapore.

When should patients consider knee replacement? Indications for Knee Replacement

The surgery is advised when other treatments fail to relieve symptoms that significantly impair quality of life. It is performed with proper precaution. Before surgery, your doctor will discuss all the necessary details with you. Before that, the following information might help you:
Most commonly, patients above 50 years of age suffer from knee pain due to osteoarthritis. In some cases, inflammatory arthritis may cause accelerated damage to the knee joint. Most patients are initiated on a conservative treatment plan which includes analgesic medications, weight loss, and physiotherapy. However, not all patients will respond to treatment. If severe knee pain continues to bother you, surgery may be necessary.
Knee replacement should be considered if patients suffer the following:

  1. Severe Knee Pain: Affecting daily activities like walking, climbing stairs, and even resting.
  2. Moderate to Severe Arthritis: Diagnosed osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis causing joint damage.
  3. Knee Stiffness and Deformity: Marked limitation in knee movement or visible deformity.
  4. Failure of Other Treatments: Ineffectiveness of medications, physical therapy, or less invasive surgeries.

You should discuss your condition with an orthopaedic specialist and know all the dos and don’ts of a fit lifestyle when you have knee pain.

What Happens Generally During knee joint replacement surgery?

Before the surgery begins, the patient is administered either general or spinal anesthesia to ensure their comfort. Once the anesthesia takes effect, we meticulously cleanse the skin surrounding the knee with a powerful antiseptic fluid. To maintain stability and precision throughout the procedure, we position the lower leg and foot in a specialized device that securely immobilizes them at a 90-degree angle.

Usually, a tourniquet is then applied to the upper portion of the leg to help slow the flow of blood during the surgery. An incision of appropriate size will then be made and the following steps will take place:

  1. Prepare the bone – The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone.
  2. Position the metal implants – The removed cartilage and bone are replaced with metal components that recreate the surface of the joint. These metal parts may be cemented or “press-fit” into the bone.
  3. Resurface the patella – The undersurface of the patella (kneecap) is cut and resurfaced with a plastic button. Some surgeons do not resurface the patella, depending on the case. Do discuss this with your surgeon if it is important to you.
  4. Insert a spacer – A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface locked in place.

What are the complications of Total Knee Arthroplasty?

Undergoing knee replacement surgery can be life-changing, but it’s crucial to be aware of potential complications. Infections, though rare, can occur at the wound site or deeper near the implant. Blood clots in the leg veins are a common concern, posing risks like deep vein thrombosis. Sometimes, even with the best surgical hands, the new knee may continue to ache or feel stiff, limiting movement. Nerve damage around the operated area might cause numbness. On very rare occasions, patients may react to the metal in the implant. 

“Remember, a thorough discussion with your surgeon and adhering to post-op care can significantly minimize these risks.”
