Traditionally, knee replacement surgery involved large incisions, significant peri-operative pain, extended hospitalization and recovery time. Patients did well with surgery; however, they experienced significant pain and limitation of activity for the first 3 months after surgery.

With the advent of mini-incision or minimally-invasive knee replacement surgery combined with new techniques in pain management and anesthesia, knee replacement surgery has become a more pleasant experience.

The advantages of mini-incison knee replacement are:

• Smaller incision approximately 5” versus 10”, more cosmetic
• No violation of the quadriceps muscle with the quad-sparing approach
• Shorter hospital stays (2-4 days vs. 1 week)
• Shorter recovery and return to usual activities in 4-6 weeks
• Less blood loss and need for transfusions
• Lower rates of complications such as blood clots, pneumonia, infection and stiffness
• Less pain and less need for pain medications

Dr. Nasar is familiar with the most advanced knee replacement implants available today. The Depuy PFC Sigma Rotating Platform, High Flexion implant combines proven performance in a mobile bearing design allowing unprecedented knee motion. This implant can be placed without the use of bone cement in selected patients. The Smith & Nephew Genesis II Oxinium implant has a special ceramic coating for maximum longevity. The Zimmer Tantalum (trabecular metal), cementless knee replacement allows completely cementless implantation where the bone bonds directly to the implants. This innovative technology is great for younger patients as it can last longer than cemented knee replacements.

Navigation (Computer assistance) for knee replacement
Navigation has been proven to increase surgical accuracy and precision in making bone cuts and placing components. It is expected to yield longer lasting knee replacements with less need for revision or repeat surgery.
