Minimally Invasive Knee Arthroplasty

Why Choose M.I.K.A.?

Each year more than 6 million people see an orthopedic surgeon for treatment of a knee problem. The primary goals of knee replacement are to reduce pain, restore limb alignment and improve function.

With recent advances in orthopedic technologies and procedures, patients can now have Minimally Invasive Knee Arthroplasty (M.I.K.A.TM). Minimally invasive surgery is a growing trend for the aging population because of its benefits of a smaller surgical incision which can help patients to heal faster and get back on their feet.

A Less Invasive Type of Knee Surgery

M.I.K.A. involves a smaller incision which can result in less bleeding, less infection risk and quicker recovery than traditional surgical methods. Thanks to advances like M.I.K.A., surgeons can use specialized smaller instruments to reduce the incision from about 10-12 inches to 4-6 inches. The shorter incision minimizes scarring and may help cut down the time the patient has to spend in the hospital. With M.I.K.A., surgeons use the same surgical technique as traditional knee replacement surgery.

The benefits of M.I.K.A. are the reduced length of rehabilitation. Because there is less blood loss and less tissue dissection, the rehabilitation process is usually quicker. Generally, immediately following surgery, patients are able to move right away and can begin rehabilitation. Total knee replacement has grown to be a very predictable surgery with fewer than 10% requiring revision at 10 years1. With M.I.K.A., we can expect to achieve these same excellent results, but with less pain during rehab.2
