Partial Knee Replacement Surgery & Robotic Partial Knee Replacement Surgery in Dubai at CMC

A partial knee replacement, also known as unicompartmental knee replacement, is a surgical procedure that is used to replace only one part of a damaged knee. The technique, which is used as an alternative to total knee replacement, is used as a treat option for individuals with joint disease resulting from degenerative and post-traumatic arthritis that is limited to one side of the knee.

Ideal Candidate for Partial Knee Replacement

For one to be considered for partial knee replacement procedure, he/she should fit certain criteria. These include:

  • Individuals with medial (inside the compartment of the joint), or lateral (inside compartment of the joint) knee osteoarthritis.
  • Before undergoing the procedure, it must be confirmed that the patient has a stable knee, an intact anterior cruciate ligament, and enough range of motion in the knee.
  • Patients whose knee pain persists even after using anti-inflammatory medications and maintaining a healthy weight.

Benefits of Partial Knee Replacement

  • Faster rehabilitation and recovery
  • Reduced post-operative pain
  • Minimal tissue trauma
  • Minimal blood loss
  • Improved range of motion in the knee
  • Preservation of all healthy bone and ligaments

Why Partial Knee Replacement is Recommended

The most frequent justification for replacing a knee joint is to relieve severe pain. However, the orthopedic surgeon may recommend a partial knee replacement if the patient is experiencing the following:

  • Persistent knee pain even after other treatments
  • The pain interferes with the patient’s daily activities
  • The knee pain interferes with the patient’s quality of life like inability to sleep

Preparation for Partial Knee Replacement

Prior to the actual procedure, the doctor will give instructions to the patient that will help him/ her prepare adequately for the same. These include:

  • The patient may need to stop taking medications that might impair his/her immune system
  • Stopping smoking as it slows the healing and recovery process
  • It might be necessary for the patient to visit a physical therapist before surgery to learn exercises that will help in recovery
  • In case the patient has some underlying medical conditions such as diabetes, heart disease, or other ailments, the doctor will advise/her to see the specialist in any of the conditions
  • The patient may also be asked to stop taking blood thinners as this may promote excessive bleeding during the procedure

The Procedure

During the procedure, which is performed under general anesthesia, a prosthetic implant is used to replace the missing tissue hence preserving the rest of the knee.

An incision about 3 to 5 inches long will be made over the patient’s knee. The surgeon, through this incision, removes the damaged bone and tissue. A component made of metal and plastic is placed into the knee. The surgeon then uses cement to affix the component once it has been placed correctly, and then the incisions are sutured and dressed.

What Happens After Partial Knee Replacement Surgery

Most patients experience a significant reduction in discomfort/pain after the surgery, and recovery is quite fast. Partial knee replacement patients heal faster than total knee replacement patients.
