You should talk with your physician about the unicompartmental procedure and how it might be beneficial in your particular situation.
 

 
Who would benefit most from this type of surgery?

Most of the patients treated are 55 or older. CSOS physicians have treated patients in their earlier 50s, but it is probably not a reasonable option for patients younger than 50.

  Some of the symptoms patients may experience include:

  • Pain when standing, switching positions, or walking
  • Persistent swollen knee
  • Locking or giving out of the knee
  • No response from other treatment options
  • How do you determine if this procedure will help me?

    An x-ray taken while you are weight-bearing must show that there is NO joint cartilage in a particular area of your knee.
     
     

    What types of activities can I expect to be able to do after the surgery?

    Because the procedure restores 1/3 of the joint surface, most of the joint remains your own tissue. Therefore, the basic structure of your knee remains the same and the implanted device is not prone to injury. Some of the activities you may be able to perform include golfing, mowing the lawn, and other light labor. It is important to talk with your doctor about any limitations you may have as a result of the surgery.
     
     

    How long does the prosthetic device usually last?

    The functional life of this implant is estimated around 8-10 years, depending on a number of variables including your age, weight, and activity level.
