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.

1. What is partial knee replacement, and when is it preferred to a total knee replacement?

Also known as unicondylar knee replacement, partial knee replacement is a surgical procedure performed to treat cases of osteoarthritis that is confined to one compartment of the knee. Not all patients are candidates for this procedure; however, those who are may benefit from the shortened post-operative recovery time, minimized invasiveness and tampering, and reduced blood loss during the surgery. In many cases, the procedure is performed on an outpatient basis, allowing patients to return home the same day of surgery.

Partial knee replacement allows the patient to maintain healthy compartments of the knee while replacing the diseased compartment. This provides patients with a more 'natural' feeling joint. Partial knee replacement stands in contrast to total knee replacement, in which the entire joint is removed and replaced with a prosthetic joint.

3. What is arthroscopy, and when is it performed?

Arthroscopy is a minimally invasive surgical procedure that utilizes fiber-optic technology. Because arthroscopic surgery may provide benefits for patients, including shorter post-operative recovery time, minimized scarring, and less blood loss during the procedure, it is commonly utilized in Sports Medicine treatment, a subspecialty of orthopedic surgery that focuses on treating athletes in a minimally invasive manner to get them back on the playing field safely.

During an arthroscopic procedure, the surgeon will create an incision on the affected joint and insert a tiny fiber-optic camera known as an "arthroscope". The arthroscope, once inserted into the joint, sends real-time video imaging to a monitor in the operating room. This gives the surgeon a clear view from within the joint without requiring a large incision. Next, the surgeon will insert the operating instruments into a second small incision, allowing the surgeon to repair the damaged components of the joint without excessively tampering with muscle and tissue.

4. What is computer-assisted surgery, and when is it best utilized?

Computer-assisted surgery is a surgical innovation that makes it possible for an orthopedist to navigate joint replacements with a level of accuracy so precise it may improve the results of the surgery. Computer-assisted navigation systems act like a mini GPS, which tracks movement within the joint and provides feedback on a computer screen. Additionally, computer-assisted navigation systems allow the surgeon to move the joint through its entire range of motion virtually, ensuring the most effective placement of the implant.

Often, computer-assisted surgery is utilized for hip and knee replacements, and provides the following surgical benefits:

  • Shorter post-operative recovery period
  • Smaller incision in comparison to traditional hip or knee replacement
  • Less Blood Loss
