When Do I Need Knee Replacement Surgery?

There are two scenarios in which you would require a knee replacement surgery. The first one is if you have sustained a severe knee injury. The second one is when the knee joint has been worn away by a degenerative condition such as osteoarthritis. For the second scenario, surgery is the last resort after all other treatment options (medications, physiotherapy, lifestyle changes) have already been exhausted.

In such cases, patients typically go for surgery if they are experiencing the following symptoms:

  1. Severe knee pain even when sitting and sleeping
  2. Chronic inflammation that interferes with daily activities
  3. Have a stiff or deformed knee

How Does Knee Replacement Surgery Help me?

The ultimate goal of performing knee replacement surgery is to relieve pain and restore function. Nevertheless, surgery is a big procedure and should be thoroughly discussed with your orthopaedic doctor before deciding. Your doctor will run a series of tests to assess the extent of your knee condition and explain the risks to you.

Related Information

If you have decided to have a knee replacement surgery, the doctor will discuss anaesthesia options with you (either general or spinal) and also run other tests to determine whether you have any other medical conditions that need to be optimised.

Other things to expect are:

  • Stopping blood-thinning medications and TCM herbs 2 weeks before surgery.
  • Stop smoking as soon as possible.
  • No eating or drinking 6 hours before surgery.

The patient is first given anesthesia (either general or spinal). After the anesthesia has taken effect, the skin around the knee is thoroughly scrubbed with an antiseptic fluid. The knee is bent about 90 degrees and the lower portion of the leg, including the foot, is placed in a special device to securely hold it in place during the surgery.

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:

  • 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.
  • 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.
  • 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 upon the case. Do discuss this with your surgeon if it is important to you.
  • Insert a spacer – A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface And locked in place.
