Partial Knee Replacement Surgery

People who experience strong pain in knees and can’t overcome it with traditional treatment should opt for a partial knee replacement. This is a modern approach that is practiced in many clinics including the Hospital of Bonifatius. Why becoming our patient, and what the peculiarities of the operation are?

What is partial knee replacement surgery?

Knee is the most sophisticated and complex joint in human body. Bearing almost the entire weight, it is prone to damage and wearing. If some part of knee is seriously ruptured, it can be fixed with partial knee replacements.

This is a procedure during which the doctor removes the damaged part of the knee and inserts implants to replace them. As a rule, surgeons replace either the medial or lateral part, or the kneecap of the joint. Partial knee replacement is preferable, if it’s possible, because fewer invasions are required, and recovery goes quicker. There’s lower chance that the body will reject artificial elements, and bones will regenerate better.

When is it done?

The most widespread reason for partial joint replacement is a strong pain caused by arthritis. The operation is suggested, if a person can’t sleep and execute daily activities, or traditional non-invasive treatment brings no relief. The operation may be the right solution, if you have arthritis only on one part of the knee.

A good candidate for partial knee arthroplasty is an older not very active person who has minor deformity in the knee, or not very bad arthritis. Besides, a person should have stable ligaments in knee and wide range of motion in it. Therefore, partial knee replacement is made in people after 60 and with relatively good physical and medical condition.


Before the operation, a person will be given general or regional anesthesia to block pain. Then the surgeon will make an opening 3-5 inches long in the skin, inspect the damaged area and use special saws to access the cartilage. It is removed, and metal covering are inserted to recreate the surface of the joint. The surgeon replaces damaged areas with a prosthetic (artificial implant made of metal or plastic).When the part is put on its place, it is fixed with bone cement. The opening is stitched. The patient is taken to the recovery room for the nurses to inspect his condition after general anesthesia. After that, someone can drive his or her home.


Partial knee replacement recovery is pretty quick, and a patient needs to move as much as possible to improve the range of motion and strengthen muscles around the knee. You can put the entire weight on the knee right away. Many people can walk after the operation using a cane or walker in the first 3-4 weeks. Physical therapy should be performed for 4-6 months. Most kinds of exercise can be done after surgery: swimming, tennis, biking, walking, but a person should avoid intense actions like jogging.

In most people, partial knee replacement can have very good results that last for 10 years and more. Before going through this procedure, you should discuss all pros and cons and success rate with your doctor.

Side effects

Although rare, there still can be some risks and partial knee replacement complications that include:

  • Blood clotting are very common for this surgery, but this condition can be avoided by taking blood thinners.
  • Infection can occur in the wound or skin around it. To prevent it, you will be given antibiotics before and after surgery.
  • Injury to vessels and nerves that can be ruptured or stitched during the operation.
  • Reaction to anesthesia.
  • Pain.
  • Need for another operation.

To prevent these outcomes, you should consult with the doctor and follow his recommendations.
