A layer of cartilage covers healthy joints, which is a strong, lubricating tissue that allows for smooth, pain-free motion. Arthritis, often known as “joint inflammation,” is a painful and difficult condition to manage.

As arthritis progresses, the cartilage thins out and eventually wears away to the bone. Walking is uncomfortable and in some cases impossible without cartilage.

What is Osteoarthritis?

Osteoarthritis, often known as “wear-and-tear” arthritis, is a condition in which the joint’s surface is destroyed and the surrounding bone thickens, causing bone on bone friction. This friction can result in significant pain and, in the worst-case scenario, loss of movement.

The following are some of the signs and symptoms of osteoarthritis:

  • Painful joints, especially after activity or periods of inactivity
  • Joint stiffness
  • Joint swelling
  • Loss of movement in the joint

What is Total Knee replacement?

The knee joint is one of the body’s largest and most complicated joints. It is made up of three elements that move and cooperate to provide smooth motion and operation. The lower end of the thigh bone rotates on the higher end of the shin bone, and the kneecap glides into a groove on the end of the femur to form the knee. The femur and tibia are connected by four major ligaments that give stability.

The entire surface of the knee joint is removed and replaced with artificial pieces in Total Knee Replacement. The following are the components of a total knee replacement:

  • The femoral component is a metal component on the thigh bone’s end.
  • The tibial component consists of a metal and plastic liner that runs along the top of the shin bone.
  • A plastic button on the kneecap, if necessary.

What is Partial Knee Replacement?

Only one side of the knee is commonly affected in the early stages of osteoarthritis. The inner side of the knee is frequently affected, although arthritis can also affect the outside side of the knee, though it is less common.

You may be able to prevent osteoarthritis from spreading and avoiding a Total Knee Replacement by undergoing a Partial Knee Replacement before the condition worsens.

A partial knee replacement, sometimes called a uni-compartmental knee replacement or Microplasty, replaces only the injured side of the knee while leaving the healthy cartilage intact. This will result in a smaller incision, the preservation of the four natural ligaments, and the use of an artificial joint that mimics natural knee movement.

Ligament Preservation

The soft tissues of the ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament) are not removed when a partial knee replacement is performed. These ligaments assist you preserve your normal movement after surgery by providing stability, balance, and support.

Uni-compartmental Knee Replacement / Part

Surgeons can sometimes do a partial knee replacement (also known as a unicompartmental knee replacement, UKR) instead of a total knee replacement, depending on how much of your knee is afflicted by arthritis (TKR). Before your surgery, the clinical staff can usually tell you whether a UKR is possible. However, the surgeon will decide whether to conduct a UKR or a TKR after inspecting the knee joint surfaces and ligaments during your surgery.

If you are a good candidate for UKR, there are a lot of advantages. These are the following:

  • Medical issues are kept to a minimum.
  • There is less blood loss during surgery, which means a blood transfusion is less likely.
  • UKR is conducted with a smaller incision and minimal damage of soft tissue.
    Recovery is more rapid.
  • After surgery, patients often have a wide range of motion in their knee.
  • Patients who have undergone this treatment report very high levels of satisfaction.

What are the risks of surgery?

Every procedure entails some level of risk. Before and after your operation, you should be informed of the following risks:

Medical problems Infection Hospital-acquired blood clots Ongoing Pain

Scar tissue may cause the knee joint to stay stiff for a small percentage of the time.

  • Bleeding
  • Nerve/Vessel/Tendon damage
  • Dislocation of bearing
  • Need for revision/re-do surgery

Pre-operative Assessment Clinic (POAC)

The purpose of the POAC is to determine your medical readiness for surgery. Many patients can be evaluated on the same day as their outpatient clinic appointment, but others will need to return on a different day for additional testing and assessment. The majority of patients will require blood tests, a urine test, an ECG (electrocardiogram), and possibly more knee x-rays. Please remember to bring all of your medications to the POAC so that we can keep track of them.

Pain relief after the operation.

It is typical to experience some pain following your joint replacement surgery, as it is with all joint replacement surgeries. Painkilling medicines will be given to you to help with this. To take home, you will be offered two or three different types of painkilling medicines. Because the multiple tablets alleviate pain in different ways, it’s best to take them together rather than as a single medicine. Even in the first 12 weeks after surgery, you should expect to be in discomfort. This will improve over time. After surgery, your discomfort is expected to improve for up to 6 months.

Frequently asked questions

One of the benefits of UKR is that it allows patients to return home on the second or third day after surgery.


This is a critical step in the recovery process since you are the only one who can restore movement and strength to your knee. During the admittance, our qualified Physiotherapist will demonstrate and teach some easy exercises. They are designed to keep your knee from becoming stiff and to strengthen the muscles around it.

Movement is not restricted (except from pain), however kneeling on your knee is not recommended until around 6 weeks after surgery.


Returning to work is contingent on your level of mobility and the nature of your job, but you must refrain from engaging in any demanding activity for at least three months (for example lifting heavy objects).

According to studies, 80% of patients will still have a fully functional UKR 20 years following surgery.


General advice about the knee exercises

After you’ve taken your pain reliever, do your exercises about 30 minutes later.
