New “Mini Knee” Replacement Less Invasive, Spares Bone, Results in Faster Recovery Using RIO Robotic Arm Interactive Orthopedic System

Baltimore, MD (PRWEB) July 11, 2011

Marc W. Hungerford, M.D., Director of Joint Replacement and Reconstruction at Mercy Medical Center, has begun performing MAKOplasty Partial Knee Resurfacing using the RIO Robotic Arm Interactive Orthopedic System. Dr. Hungerford, a board certified orthopedic surgeon, is the first in the State of Maryland to offer this procedure to patients.

“Total knee arthroplasty (TKA) or replacement remains the “Ëœgold standard’ for treating degenerative joint disease. While proven to be a very successful procedure, it’s an invasive and requires extensive rehabilitation. It is also best suited for patients with late stage osteoarthritis””that is, where all three compartments of the knee are affected. MAKOplasty Partial Knee Resurfacing offers a less invasive option for patients living with early to mid-stage knee osteoarthritis,” Dr. Hungerford said.

Benefits of the MAKOplasty Partial Knee Resurfacing include:

“¢Ã¯ Ã¯ Joint resurfacing

“¢Ã¯ Ã¯ Bone sparing

“¢Ã¯ Ã¯ Smaller incision

“¢Ã¯ Ã¯ Less scarring

“¢Ã¯ Ã¯ Reduced blood loss

“¢Ã¯ Ã¯ Minimal hospitalization

“¢Ã¯ Ã¯ Rapid recovery

“Key to this procedure is the RIO Robotic Arm Interactive Orthopedic System. During surgery, the RIO provides the surgeon with real-time visual, tactile and auditory feedback which optimizes joint resurfacing and implant positioning. It helps the surgeon place the implant which is crucial to achieving natural knee motion for the patient after surgery,” Dr. Hungerford said.

Proper implant alignment and precise positioning during surgery, as afforded by the RIO Robotic Arm Interactive Orthopedic System, can improve the life expectancy of an implant.

“The use of RIO helps ensure the knee implant is properly aligned and positioned to ensure long implant life. In addition, because very little bone is actually removed during this procedure, the implants can be easily replaced should another procedure, like a total knee replacement, eventually be necessary,” Dr. Hungerford added.

According to Dr. Hungerford, in traditional knee replacement surgery, at least the Anterior Cruciate Ligament and frequently the Posterior Cruciate ligaments are cut and the entire joint surface is removed and replaced with an artificial implant.

“TKA performed in patients with early stage osteoarthritis typically involves removing healthy cartilage. It’s not surprising that a recent Duke University study revealed that over 90 percent of men and women would decline having total knee surgery. On average, about 600,000 patients undergo TKA, though there are about 15 million people who suffer from knee osteoarthritis. Now we have another option to offer patients who are reticent about TKA,” Dr. Hungerford said.

Hospital stays average from one to three days. Dr. Hungerford noted that in many cases, patients are walking soon after surgery, driving a car within a few weeks and returning to their normal activities shortly thereafter.

“With the RIO Robotic Arm, we marry the tools with the technique to achieve the best possible result for patients suffering with early to mid-stage knee OA. We resurface the diseased portion of the knee, sparing the patient’s healthy bone and surrounding tissue. An implant is then secured to the joint so the knee can move smoothly again,” Dr. Hungerford explained.

Osteoarthritis (OA) is the most common form of arthritis and leading cause of disability worldwide. OA is a degenerative joint disease characterized by the breakdown and eventual loss of joint cartilage, the cushion between bones of a joint. Patients with OA have had the top layer of cartilage break down and wear away, causing bones under the cartilage to rub together, causing pain.

Symptoms of knee osteoarthritis include pain while standing or walking short distances, climbing up or down stairs, getting in and out of chairs, swelling, a grating sensation or crunching feeling in the knee during use, joint stiffness, etc.

Dr. Hungerford has expertise in minimally invasive anterior approach hip replacement approach, total knee replacement, and partial knee replacement. He also focuses on adult joint replacement and preservation including hip, knee, and shoulder arthroscopy; pelvic osteotomy; minimally invasive joint replacement; revision joint replacement; and treatment of avascular necrosis. Dr. Hungerford has a research interest in joint biomechanics, osteonecrosis, and minimally invasive surgery. He has published and lectured extensively on these topics.
