Partial Knee Replacement

Dr. Samani Partial Knee Replacement

What is a Partial Knee Replacement?

Often, only one side of the knee is damaged. This is usually the inner side of the knee. Still, although less common, arthritis can also affect the outer side of the knee. A partial knee replacement, also known as a unicompartmental knee replacement, will replace only the damaged side of the knee; This process preserves the normal undamaged cartilage. This may result in a smaller incision, keeping the four natural ligaments and an artificial joint that functions more like the natural knee movement.

By undergoing a partial knee replacement, the soft tissues, ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament), are kept intact and are not removed. These ligaments help provide stability and increased balance to preserve your natural movement after surgery.

Studies have found that approximately 20% to 40% of knee replacement patients are potential candidates for partial knee replacement. With total knee replacement, the natural ligaments, the ACL and PCL, are often removed (see attached illustration). The implant must then provide the stability to the knee instead of the natural ligaments. With modern materials, improvements in techniques, and antibiotic therapy, total knee replacement can be a successful operation.

The Zimmer Biomet Partial Knee Replacement is minimally invasive and has numerous benefits, including:

  • A more natural fit compared to other surgeries and procedures
  • An increased range of knee motion
  • Patients are more likely to return to sports and walk longer
  • Rapid recovery allows patients a faster return and shorter hospital stay
  • A less invasive procedure, retaining ligaments
