Robotic Assisted Partial Knee Surgery

Robotic assisted partial knee surgery is an innovative alternative to the conventional surgical procedure in patients suffering from degenerative knee diseases such as osteoarthritis. It is performed using robotic-arm technology that allows the surgeon to precisely perform the surgery through a smaller incision as compared to traditional surgery.

This procedure utilizes X-rays and CT scans to determine the damaged areas, of the joint, that need to be removed for the precise placement of the knee implant. The procedure may be used for total or partial knee surgery. In the partial knee resurfacing, only the diseased portion of your knee is removed, preserving the surrounding healthy bone and tissue. An implant is then secured over the prepared portion of your knee joint that results in resolution of symptoms and a natural knee movement. As it employs a minimally invasive technique the incidence of scarring and blood loss is very low. Much like the GPS in your phone, the surgical robot offers precision measurements down to fractions of a millimeter to show where and how surgeons should make their surgical maneuvers – which reduces patient infections and limits exposure. During precise surgeries such as knee replacements, this can also hasten recovery time when compared to conventional surgery. Rest assured, even though the robot gives input, the surgeon always stays in complete control of the situation and tells the robot exactly when to engage and to what degree. In most cases, the robot simply assists the surgeon in measuring microscopic variations in rotations, angles, turns, and bends to give an exact precision for the placements and cuts. In this way, the surgeon can reduce blood loss, unnecessary scarring, and reduce post-surgical infections.

The procedure is beneficial in patients with unicompartmental or bicompartmental knee disease. Robotic assisted partial knee surgery can be considered in patients with early to mid-stage osteoarthritis associated with symptoms such as knee pain, knee swelling, and knee locking. The procedure results in resolution of symptoms and a natural knee movement.


The benefits of the robotic assisted partial knee surgery include:

  • Smaller incisions
  • Rapid recovery
  • Precise placement of the implant
  • Reduced injury to adjacent tissues
  • Increased longevity of the implant
