Partial Knee Replacement Q&A

What is a partial knee replacement?

A partial knee replacement is a joint replacement procedure that only removes and replaces one compartment in your knee. 

Your knee has three compartments, including the medial (inside), lateral (outside), and patellofemoral (kneecap). Arthritis is a common cause of knee pain and knee damage that may affect the entire knee joint or only one compartment. 

During a partial knee replacement, Dr. Berni removes and replaces only one knee compartment. For a total knee replacement, he replaces the entire knee joint.

Am I a candidate for a partial knee replacement?

Dr. Berni determines if you’re a candidate for a partial knee replacement during a consultation. If you have advanced osteoarthritis in your knee that no longer responds to medical treatment (medication, physical therapy, or injections), then Dr. Berni may recommend knee replacement.

Additionally, to be a candidate for the partial knee replacement, your advanced arthritis must only affect one knee compartment. 

What happens during a partial knee replacement?

Dr. Berni creates individual partial knee replacement surgical plans based on the compartment he’s replacing. He reviews the details of his plan with you during your pre-surgical visit.

When performing a partial knee replacement, Dr. Berni uses small incisions and advanced surgical tools to reduce scarring, pain, and recovery time. 

He removes the damaged portion of the knee, positions the metal implant, and inserts a spacer that separates the metal components, allowing them to glide over each other. 

Dr. Berni then closes the wound and sends you to the recovery room for monitoring. You may need to spend up to three days in the hospital following your partial knee replacement. However, when possible, Dr. Berni sends you home the same day. 

What are the benefits of a partial knee replacement?

Many patients report good results following a partial knee replacement. Benefits of the procedure include:

  • Less invasive
  • Minimal blood loss
  • Shorter surgery
  • Faster recovery
  • Less post-surgical pain
  • Preservation of ligaments

When performing a partial knee replacement, Dr. Berni doesn’t remove the cruciate ligament that crisscrosses the knee to connect the femur to the tibia. By preserving natural ligaments, the partial knee replacement helps your knee retain its normal biomechanics.

Compared to a total knee replacement, your knee may feel more natural and have better range of motion.
