MAKOplasty

Robotic-assisted surgery is a minimally invasive procedure where your surgeon is assisted by a robotic system to perform the surgery.

The robotic system consists of a surgeon's console, robotic arms, a high-performance vision system and special surgical instruments. A computed tomography (CT) scan is taken before the surgery to create a 3D model of the affected hip or knee joint. This is interpreted by the system, which accurately guides your surgeon. Unlike a traditional surgery, this procedure is performed through small incisions. The 3D camera provides your surgeon with a magnified view of the operating area. Your surgeon sits at a console and controls the movement of the robotic arms holding the special surgical instruments. The movements of your surgeon's hands are translated by the robotic system into precise movements of the miniaturized instruments that are held by the robotic arms.

The enhanced vision and superior control of the micro-instruments improves the precision of the surgery. This accuracy helps repair the damaged joint and optimally position any prosthetic implant for a more natural feeling joint after surgery, while ensuring minimal injury to neighboring tissues. Being a minimally invasive procedure, benefits include less post-operative pain, shorter hospital stay, rapid recovery and faster return to daily activities when compared to traditional joint surgeries.

Am I Candidate for Robotic-assisted Surgery?

Candidates for robotic-assisted surgery include:

  • Osteoarthritis of the knee
  • Degenerative hip disease
  • No relief from pain and disability with non-surgical treatment and medication
  • Partial knee resurfacing
  • Total hip replacement

Robotic Assisted Knee Surgery/Makoplasty

MAKOplasty® is a novel surgical procedure performed to relieve pain caused by joint degeneration due to 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.

Patients suffering from unicompartmental or bicompartmental knee disease may benefit from MAKOplasty® partial knee resurfacing. Patients with osteoarthritis symptoms such as knee pain associated with activity, knee swelling, knee locking and failure to respond to non-surgical treatment would be good candidates for the MAKOplasty® procedure.

Your doctor may order a few X-rays and CT scan to determine the damaged areas of the joint that need to be removed for the precise placement of the knee implant.

During the MAKOplasty® procedure, a four to six-inch incision is made over your knee with small incisions over your thigh bone (femur) and shin bone (tibia). 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 resulting in resolution of symptoms and a natural knee movement.

Benefits

MAKOplasty ® offers the following benefits:

  • Replaces only the arthritic portion of the joint
  • More ideal joint function
  • Accurate implant positioning
  • Smaller incision
  • Bone and tissue sparing
  • Minimal hospitalization
  • Rapid recovery

Since healthy bone is preserved, patients who undergo MAKOplasty® may have a total knee replacement procedure later, if required. MAKOplasty® is usually covered by health insurance. Your doctor will discuss the associated benefits and risks of the procedure.

MAKOplasty® Partial Knee Resurfacing

Who would be a good candidate for the MAKOplasty® procedure? 

Although the best treatment for each patient must be determined individually, typical MAKOplasty® patients share the following characteristics:

Knee pain with activity, on the inner knee, under the knee cap or the outer knee.

Startup knee pain or stiffness when activities are initiated from a sitting position.

Failure to respond to non-surgical treatment such as rest, weight loss, physical therapy and non-steroidal anti-inflammatory medication.

VISIONAIRE Patient Specific Surgery

VISIONAIRE Patient Specific surgery is new technology developed for total knee replacement surgery. It involves designing and creating a customized set of cutting guides based upon the patient’s own MRI and X-Ray results.

VISIONAIRE Patient Specific surgery is applicable for any patient who is considering total knee replacement surgery.

Prior to the surgery several MRI scans and X-rays are taken to view the specific anatomy of the patient’s knee joint. The MRI and X-Rays are then uploaded into special computer software which then maps out the anatomy of the patient’s knee. Special cutting blocks and instruments are then designed specifically to match the natural shape of the articulating surfaces of the patient’s knee. The surgeon can then plan the surgery and calculate the precise cutting measurements to remove the necessary amount of bone at specific angles in order to position the knee implant in the most optimal alignment. Misalignment can potentially lead to early implant failure so proper alignment is crucial to the success of any knee replacement surgery.

The customized cuts obtained from Visionaire technology provide better implantation, more reliable alignment and remove multiple steps from the traditional surgical technique thus reducing blood loss, time under anesthesia, removal of less amount of bone and possibly a lower risk of infection.

Signature Knees

The knee joint, made up of the ends of the femur (thigh bone) and tibia (shin bone) is cushioned by a spongy tissue called cartilage. Damage and wear and tear of the cartilage causes painful rubbing of the joint bones, leading to disability. This condition can be successfully treated with knee replacement surgery, which involves the replacement of the damaged tissue with a prosthetic implant.

Signature knee system

Signature knee is a unique knee replacement procedure that is tailored to suit your individual anatomy. The technique utilizes magnetic resonance imaging (MRI) technology to create 3D images of your knee joint, which enables your doctor to efficiently plan your knee replacement surgery. The signature system also helps design and create patient-specific femoral and tibial positioning guides that will be used during the knee replacement surgery to ensure a perfect fit of the knee implant.

Signature vs. traditional knee replacement

Before the knee replacement surgery, the signature system requires an MRI scan to obtain 3D images of the knee joint, while traditional surgeries are based on 2D images generated by X-rays. While the traditional procedure uses and places multiple instruments to assist and verify proper alignment and positioning of the implant, the signature system uses customized positioning guides directly on the femur and tibia bones and does not require any instrumentation of the bone canal, enabling a less invasive surgery.

Advantages of signature knee replacement

The following are the advantages of the signature knee system:

  • It is a very specific and personalized approach to knee replacement.
  • It is based on the unique anatomy of an individual.
  • It uses 3D MRI instead of 2D X-ray.
  • It helps your doctor position the implant accurately, as the guides are patient- matched.
