Partial Knee Replacement


Partial Knee Replacement

Dr. Gallivan uses the Mako Robot while performing partial knee replacements. A partial knee replacement involves replacing the damaged surface(s) of the knee joint with a metal and plastic component.  

A partial knee replacement includes a unicompartmental knee replacement or a bicompartmental knee replacement. There are three compartments of the knee joint, which include, the medial compartment, the lateral compartment and the patellofemoral compartment. A unicompartmental knee replacement involves the replacement of one compartment in the knee joint, whereas a bicompartmental knee replacement involves the replacement of two compartments in the knee joint.  

Dr. Gallivan prefers to use a spinal anesthetic during surgery rather than putting patients under general anesthesia, because it is safer for the patient. 

When Should I Decide to Have a Partial Knee Replacement? 

Dr. Gallivan believes that there are five main reasons individuals elect to proceed with partial knee surgery after attempting non-operative treatment. These include:  

  1. The pain has become unbearable and/or is greater than one wants to live with.   
  2. The pain has impacted quality of life and one is no longer able to achieve their personal functional goals.   
  3. One's overall health, cardiovascular fitness, and longevity is compromised due to the inability to exercise due to pain.   
  4. The patient has complete loss of cartilage in lateral compartment and resulting instability issues are increasing the incidence of falls. 
  5. The patient has a progressive deformity that will impact future positive surgical outcomes.
