Partial Knee Replacement SurgeryIf you are considering knee surgery, the following partial knee replacement information may help you understand your alternatives.
Knee pain from arthritis can be particularly debilitating because we use our knees in almost all of our daily activities. If you are experiencing severe knee pain that interferes with your normal functioning, your doctor may recommend a partial knee replacement, also known as uni-compartmental knee replacement.
This procedure is much less invasive than total knee replacement and may give relief to people suffering from arthritis of the knee or a knee injury. Partial knee replacement surgery replaces only the damaged area of your knee joint, may require only one day of hospitalization, and results in dramatically less recovery time when compared with total knee replacement surgery.
The knee can be divided into three compartments: the medial compartment, the lateral compartment, and the patello-femoral compartment. The uni-compartmental implant is designed to replace either the medial or lateral compartment.

Minimally Invasive Partial Knee Replacement
There is no disruption of the knee cap, which leads to more rapid rehabilitation.
There is minimal blood loss in a partial knee replacement. The procedure causes less post-operative pain and requires greatly reduced hospitalization compared to a total knee replacement.
There is also a reduced need for anesthesia and post-operative medication.
After the surgery, patients are able to walk within 3 to 4 hours and experience a much faster rehabilitation and recovery (2 to 5 weeks for many patients). After achieving full recovery, most patients experience an increased range of motion when compared to total knee replacement.

You will be discharged when you can get out of bed on your own and walk with a walker or crutches, walk up and down three steps, bend your knee 90 degrees and straighten your knee.
You’ll continue your home exercise program and go to outpatient physical therapy, where you will work on an advanced strengthening program and such programs as stationary cycling, walking, and aquatic therapy.
Your long-term rehabilitation goals are a range of motion from 100-120 degrees of knee flexion, mild or no pain with walking or other functional activities, and independence in all activities of daily living.
