Published on Feb 27, 2016 Virtual Knee Replacement Surgery is a science game for students and patients and their caregivers to take on the role of a surgeon and complete a knee replacement surgery while learning about the procedure, the technology, and health risks and benefits. Activity includes photos of real surgery.

More rapid return of knee function. Patients who undergo this procedure seem to get muscle strength and control back more quickly than patients who have had traditional total knee replacement. This is because the quadriceps muscle and tendon are not divided in the course of the surgical exposure like in traditional knee replacement, and the kneecap is not everted (flipped out of the way) as it is in traditional total knee replacement.

Decreased post-operative pain may be a function of the smaller incision and the fact that the incision stays out of the important quadriceps muscle/tendon group. Using Quadriceps-Sparing Knee Replacement.
New Quad Sparing Technique May Provide Faster Recovery for Patients with Arthritis of the Knee
Minimally-invasive quadriceps-sparing total knee replacement is a new surgical technique that allows surgeons to insert the same time-tested reliable knee replacement implants through a shorter incision using surgical approach that avoids trauma to the quadriceps muscle (see figure 1) which is the most important muscle group around the knee. This new technique which is sometimes called quadriceps-sparing knee replacement uses an incision that is typically only 3-4” in length (see figure 2) and the recovery time is much quicker – often permitting patients to walk with a cane within a couple of weeks of surgery or even earlier. The less-traumatic nature of the surgical approach also may decrease post-operative pain and diminish the need for rehab and therapy compared to more traditional approaches.
The main potential benefits of this new technique include:
- More rapid return of knee function.
To truly spare the quadriceps tendon from any cutting, a different variation of minimally invasive surgery, called quadriceps-sparing knee replacement, can be used. This surgical approach is not new. Another name for it is the subvastus approach. “Subvastus approach” means going under the vastus muscle, which is part of the quadriceps muscle group. In essence, the surgeon makes a small (3- to 4-inch) skin opening. Next, the surgeon opens a fibrous layer of tissue (called the retinaculum) attached to the quadriceps muscle. and enters the knee joint. Finally, to expose the knee joint enough to insert the replacement, the surgeon takes the cut in the retinaculum further up into the thigh. This is done without cutting or injuring the quadriceps tendon. The quadriceps muscle is instead lifted up out of the way, so special instruments can be positioned for the operation.
he incision for the quadriceps-sparing knee replacement is only as large as is necessary to place the replacement parts in the body.… Read the rest
Dr. Michael Messieh offers a minimally invasive, muscle sparing approach to knee replacement surgery. The muscles over the knee are not cut but rather lifted up out of the way. This medial side approach may result in significantly faster recovery and more strength and mobility in the new knee.
Our program is often results in the majority of patients going home in 2 days or less!
• Our patients report pain levels < 2 on a scale of 0 to 10 at the time of discharge from the hospital
• Our patients walk more than 100ft before they go home from the hospital!
• The majority of our patients are just using a cane 1 week after surgery!
Few orthopedic surgeons are trained in this procedure.

Smith & Nephew is jumping into the growing field of robotically assisted knee surgery by acquiring Plymouth’s Blue Belt Technologies for $275 million…
…Blue Belt makes a computer-assisted surgical drill called the Navio that is approved for partial-knee replacement surgeries. The computer allows a doctor to treat a partly arthritic knee by precisely drilling out a compartment in a patient’s lower femur bone to make space for a new metal implant…
…Blue Belt’s Navio system has no robotic arm. Rather, the doctor uses a freehand bone drill whose bur is retracted or stopped automatically when the computer senses that the tool is outside the three-dimensional zone where bone is supposed to be cut…
