The most common reason for knee replacement surgery is osteoarthritis. Osteoarthritis in the knee occurs when the articular cartilage becomes damaged through natural wear and tear. The bones then have little or no protection to prevent them from rubbing against each other and knee movement causes pain. Other medical conditions that may make a knee replacement necessary include: rheumatoid arthritis, post traumatic arthritis, etc.

Replacing a damaged knee

Replacing the damaged knee joint with an artificial one can help reduce pain and increase mobility.

Most people who undergo a knee replacement tend to be aged between 60 and 80. With the present advances in medical technology, it is now safely done even at an advanced age. Sometimes it is required in younger people also. The surgery usually takes 1-3 hours.

Complications

All surgeries carries a slight degree of risk. However, most people do not have any complications. Knee replacement surgery is now a routine and commonly performed operation. Someone who is fit and with no other medical problems will be at a lower risk than a person with multiple medical conditions.

Infection can be reduced by using antibiotics at the time of surgery and by using ‘clean air’ ventilation in Operation Theatre. Deeper infection is serious and requires removal and re-implantation of the joint. Blood clots (thromboses) may also form in the deep leg veins as a result of reduced movement in the leg during the first few weeks after surgery. They can be prevented by using special support stockings, starting to walk or exercise soon after surgery, and by using anticoagulant medicines.

Recovery

You will need to stay in hospital for 4-10 days, during your hospital stay you will see a physiotherapist who will give you some exercises to help you recover. After 3-4 days you will be using a walker or walking stick to move around. Physiotherapy (exercises) is an important part of your recovery, so it is vital that you continue with exercises once you are at home. Most people find it possible to resume normal leisure activities 3-6 weeks after their surgery. However, it may take up to three months for your pain and swelling to settle down. Most people are also able to return to work at six weeks’ time from surgery. Sometimes patients are able to take few steps even after next day of surgery.

Partial Knee replacement

Partial Knee replacement or Unicompartmental Knee Replacement (UKR) is done when the damage is caused to only the partial part of the knee.

Targeted Approach to Knee Joint Damage

Unicompartmental Knee Replacement (UKR) is specifically designed to address specific area of knee joint damage. It preserves 70-75% of normal bone, replacing only the damaged portion and leading to a less invasive procedure with faster recovery. Unlike Total Knee Replacement (TKR) where ligament(s) is removed, UKR retains all ligament integrity, providing a natural feeling and near-normal knee movements.

With UKR, you can enhance the quality of your life and regain the confidence to perform daily activities without the burden of knee pain. Whether it's playing with your grandchildren or engaging in hobbies you love, UKR aims to restore knee function, allowing you to enjoy the things you cherish.
