What are the different types of partial knee replacements?
There are a few different types of partial knees. The inside of your knee is considered the “medial compartment”. Meanwhile the outside of the knee is the “lateral compartment”. The part underneath the knee cap is called the “patellofemoral compartment”. Each of these compartments can be replaced independently with a lateral, medial or patellofemoral replacement. Sometimes two compartments can be replaced, a “bicompartmental replacement”

Frequently Asked Questions about Partial Knee Replacement (FAQ)
Partial knee replacements that are done for the right reasons can last a lifetime. Patients who are heavier, have a higher activity level, or have arthritis in other areas of their knee are at a higher risk for failure. At 10 years, 90% of partial knees done with historical techniques are still functioning well. Using robotic assistance, surgeries are able to have their implants placed in better positions, and the longevity approaches that of total knees, while maintaining the improved kinematics from a partial knee.
Partial knee replacements are a good surgical option for patients who have to isolated osteoarthritis to only one compartment. The knee is made of three compartments – medial, lateral, and patellofemoral. Partial knee replacements in patients with arthritis in more than one compartment are at high risk of failure after a partial knee replacement.
Comparatively, there is less surgery associated with a partial knee replacement. This results in less blood loss, less pain, and quicker recovery. Patients are generally able to return home on the same day of surgery. You are able to shower right away. After about 6 weeks, most patients are able to return to many of their normal activities.
Recovery from a partial knee replacement is generally faster compared to a total knee replacement. Partial knee replacements usually recover between 4 and 10 weeks. Total knee replacements can take between 8 to 12 weeks for a recovery.
Partial and total knee replacement surgery have excellent track records. There are risks and benefits to both operations. Partial knee replacements often leave patients with a more “natural feeling” knee, while total knee replacements are able to provide the longest term result with lower risk of re-operation.
