Jackson Partial Knee Replacement

Procedures to Repair Damaged Parts of the Knee

The knee consists of several parts, including the medial (inside) section, outside (lateral) section, and kneecap. If only one or two of these components are damaged, a partial knee replacement can repair the joint. Like other joint replacement procedures, partial knee surgery should only be used as a last resort when more conservative options fail.

Candidates for Partial Knee Replacement

Partial knee replacement is most often recommended for patients with early-stage osteoarthritis – before the disease has a chance to spread. Arthritis that has spread to three or more parts of the knee requires total knee replacement surgery.

You may be a candidate for partial knee surgery if you meet the following criteria:

  • Your pain has not improved with medication, physical therapy, or other conservative treatments
  • You have trouble moving your knee and experience daily pain.
  • The anterior cruciate ligament is still intact and uninjured
  • Only one or two parts of the knee have been damaged by injury or arthritis

Benefits of Partial Knee Replacement

Compared to total knee replacement, partial knee replacements is more precise and preserves more range of motion for the joint. It leaves healthy knee tissue intact, removing only the damaged and diseased portions. This leads to less blood loss during the surgery and a faster recovery.

St John’s Health uses the Mako Robotic Arm to perform partial joint replacements. This state-of-the-art surgical device uses imaging results from CT scans to build a customized surgical plan. The Mako Robotic arm is very precise, and all of its movements are controlled by a specially trained.

Expected Results

You should be able to start moving your knee immediately after the surgery. Full function is expected to return over the following weeks as the pain subsides. During physical therapy, you will spend several weeks easing the knee back into normal function. Most patients are back to an active lifestyle in approximately six to eight weeks. Although some activities like running may be too strenuous even after your recovery, partial knee replacement still allows you to engage in activities such as tennis, skiing, and other sports.
