Advances in Knee Replacements

This new design allows surgeons to preserve the important central ligaments of the knee called the anterior and posterior cruciate ligaments. This design should allow a knee replacement to move, respond, and feel more like a normal knee.

The Anterior Hip

Patients are being told by both surgeons and orthopedic implant companies that Anterior Hip Replacement approach offers something unique and different compared to other approaches. This is a flatly untrue, unscientifically supported myth...

MAKOplasty® for Partial Knee Replacement: Portland, OR

partial knee resurfacingPartial knee resurfacing is a minimally invasive procedure that has been performed since the 1970's to alleviate osteoarthritis of the knee. This procedure is preferred to total knee replacement whenever osteoarthritis is confined to only one compartment of the knee. By removing only the damaged portion of the knee joint, the surgeon can preserve healthy bone, giving the patient a more natural feeling knee.

Portland-area joint replacement specialist, Dr. James Ballard, utilizes robotic surgery to offer patients a new method of partial knee resurfacing, which preserves the natural feeling of the knee by adding a level of precision through the use of robotics and computer navigation. With the assistance of an advanced visualization system and a robotic arm, Dr. Ballard is able to plan and perform partial knee resurfacing surgery that allows the implants to be customized specifically to a patient's anatomy.

Partial Knee Resurfacing Surgery

In a traditional partial knee resurfacing surgery, the surgeon will make an incision at the front of the joint and remove the damaged cartilage from the diseased compartment of the knee. The ends of the femur and tibia are then shaved down to fit metal components, which are held to the bone with cement. A plastic component is inserted between the two metal components to allow for a smooth gliding surface.

MAKOplasty® Partial Knee Resurfacing

With the addition of the MAKOplasty® robotic arm to Dr. Ballard’s Oregon City, OR practice, the surgeon can visualize the patient’s anatomy and pre-plan the operation. This minimally invasive procedure makes bone preservation and customized implant positioning possible.

“It fine-tunes the placement of the pieces. The computer will show you how pieces will marry each other. The robotic arm carves out what you planned. It lets you plan this entire thing before you even touch the person, which is completely unheard of.”
– Dr. Ballard on MAKOplasty® Robotic Assisted Surgery

Benefits of Partial Knee Resurfacing with MAKOplasty®

While traditional knee resurfacing has proven to be incredibly successful, partial knee resurfacing utilizing robotic assisted surgery offers a quicker recovery and a more natural feel. In a total knee replacement, the knee surgeon must remove several key internal ligaments that connect to the knee. MAKOplasty® preserves those key internal ligaments, leading to a more normally functioning knee.

Potential benefits of robotic assisted surgery include:

  • Improved placement that leads to a more natural feeling knee
  • Shorter hospital stay
  • More rapid recovery
  • Significantly reduced scarring

While partial knee resurfacing offers a relatively shorter hospital stay in comparison to total knee replacement, MAKOplasty® extends the potential benefits of the minimally invasive procedure even further. The post-operative hospital stay for MAKOplasty® patients is one to two days, with recovery lasting two to six weeks.
