The knee is one of the most commonly injured joints in our body. The sensation of “clicking” in the knee is common, but may not indicate structural damage.

If you’re experiencing swelling in the knee after sport or just after an evening walk, it certainly warrants a check-up. Whether you’re having a “runner’s knee” or you’re worried there’s damage to the knee ligaments and cartilage, we can help you get back to your best.

Knee Conditions and Treatments we perform include:

  • Anterior knee pain syndrome
  • Cruciate ligament injuries (ACL / PCL)
    SummaryAnterior Cruciate Ligament Tear or ACL Tear is the overstretching or tearing of the anterior cruciate ligament (ACL) in the knee. The tear may be partial or complete. This most commonly occurs with pivoting, rapid deceleration, cutting movements or twisting injuries.
    TreatmentACL or Anterior Cruciate Ligament surgery is a day surgery procedure that requires a graft of a tendon. This can be harvested from the patient’s own hamstring, or patellar tendon. In some cases, tendons from a cadaveric donor can be obtained to reconstruct the ACL.
    DurationSurgery can take 1-2 hours depending on the complexity and structures injured.
  • Cartilage injuries
  • Meniscal tears
    Summary An injury to one of the bands of rubbery cartilage that act as shock absorbers for the knee. A meniscus tear can occur when the knee is suddenly twisted while the foot is planted on the ground. A tear can also develop slowly as the meniscus loses resiliency.
    TreatmentPatients with complex or large tears may require surgery. Arthroscopic or key-hole surgery is commonly done to address the meniscus. Treatment options include repairing the meniscus, or removing the damaged portion during surgery. Your surgeon will assess and decide if the meniscus tear
    DurationEstimated 1 hour, and often as a day surgery procedure.
  • Knee arthroscopy
    SummaryA knee arthroscopy is the surgical procedure doctors use in order to get a better look at the knee joint without the need for a large incision through the skin and other surrounding soft tissues. Our surgeon may use arthroscopy to aid in the diagnosis and treatment of a wide range of knee conditions.
    Treatment A knee arthroscopy has minimal pain as it is performed through a small incision. Your surgeon will insert the arthroscope and survey the condition of your knee. Procedures to treat specific injuries such as meniscus and cartilage repairs, and ACL reconstruction can be done through the same key-hole incisions with the help of special instruments.

    Duration Depending on the complexity of the injury, surgery can take between 1-1.5 hours.
  • Knee pain
    SummaryThe knee is a big complex joint that is essential for us to walk and run. Knee pain can be sharp and painful, after a twisting injury or sprain. Dull aching pain from the knee can arise from the joint itself, and often is related to cartilage wear.
    Treatment Minor aches and pains will usually improve by a week of rest, cold therapy and stretches. For acute pain and swelling after an injury, it is advisable to seek medical attention early. Chronic pain that does not improve with rest and therapy should also get an evaluation.

    Duration Recovery depends on the etiology of the pain
  • Osteoarthritis and inflammatory arthritis of the knee
    Summary Osteoarthritis is the inflammation and deterioration of cartilage within the joint, and is also known as degenerative joint disease. It occurs slowly over time and is more common in persons above 50 years of age. It affects many joints in our body including the spine, hand and fingers, and hips. The knee is a very common location of osteoarthritis to occur.
    Treatment Patients can have mild to moderate symptoms and this is usually well managed with periods of rest and activity modification. In severe cases, surgery such as partial or total knee replacement is a good option to treat osteoarthritis of the knee.

    Duration Knee replacement surgery takes 1.5-2 hours.
  • Ligament injuries and instability of the knee
  • Patella instability and dislocations
  • Partial knee replacement (including Robotic partial knee replacement)
    SummaryA partial knee replacement (PKR) can be an alternative to a total knee replacement. The surgery can be done for patients with arthritis in mainly one compartment of the knee. Surgery aims to replace the diseased cartilage in the affected compartment, preserving the knee’s native ligaments and restoring its pre-disease alignment.
    TreatmentThe surgery uses a direct approach to the medial compartment. In most cases, the scar for the PKR is about half the length of a total knee incision. Work is confined to a single compartment and done with precise instruments, resulting in less bone loss and surrounding tissue damage.

    Duration The average PKR patient stays for just 2 days, and has a lower 30-day readmission rate to hospital.
  • Total knee replacement (including Robotic total knee replacement)
    SummaryKnee replacement surgery, also known as knee arthroplasty, involves replacing the damaged cartilage and bone in the knee with metal implants and high-grade plastic components. This surgery helps to relieve pain and restore function in patients who were otherwise having difficulty walking.
    Treatment A knee replacement is done under General or Regional (Spinal) Anaesthesia. Your surgeon will make an incision between 10-15 cm at the front of the knee. Your surgeon will remove damaged cartilage and bone from the knee. The metal implants and polyethylene liner will be accurately sized and placed to achieve a balanced, stable knee joint. Dr Kau uses Computer Navigation or Robotics during the surgery to help patients get the best accurate and consistent results.
    Duration Knee replacement surgery takes 1.5 – 2 hours to complete.
  • Revision knee replacement
  • Injections around the knee and Viscosupplementation
