Minimally invasive procedure to treat early to mid-stage osteoarthritis can provide quicker rehabilitation and more natural knee motion post-surgery Tampa (July 29, 2009) - Tampa General Hospital announced today that it is the first hospital in the region to perform MAKOplasty®, a new, minimally invasive partial knee resurfacing procedure used to treat early to mid-stage osteoarthritis of the knee. MAKOplasty®, powered by the RIO Robotic Arm Interactive Orthopedic system, offers a more precise and consistent result for partial knee resurfacing. MAKOplasty® can be performed to treat osteoarthritis (OA) on two parts of the knee: the medial (inner) portion, the patellofemoral (front) portion, or both. Most MAKOplasty® patients experience a shorter hospital stay, quicker rehabilitation and a smaller scar. In addition, many are able to return to an active lifestyle within weeks of the procedure. “This technology is for knee arthritis patients who require partial knee replacements. The MAKOplasty® robot allows us to treat patients with knee osteoarthritis at earlier stages and with greater precision. Because it is less invasive and more of the patient’s natural knee remains, the goal is for patients to have more natural knee motion post-operatively,” said Dr. Thomas Bernasek, Vice Chief of Orthopedics at Tampa General Hospital and on the Board of Directors with the Florida Orthopaedic Institute. The opportunity for early intervention is important as OA is the most common form of arthritis and a leading cause of disability worldwide, according to the American Academy of Orthopaedic Surgeons. Through its innovative use of technology, MAKOplasty® takes partial knee resurfacing to a new level of precision. When performing MAKOplasty®, surgeons at Tampa General utilize the RIO, developed by MAKO Surgical Corp., which features a tactile robotic arm and a 3-D virtual patient specific visualization system. This system provides the surgeon a pre-surgical plan that details the technique for bone preparation and customized implant positioning using a CT scan of the patient’s knee. During the procedure, the system creates a three-dimensional live-action, virtual view of the patient’s bone surface and correlates the image to the pre-programmed surgical plan. As the surgeon uses the robotic arm, its tactile, acoustic and visual feedback limits the bone preparation to the diseased areas and provides for more optimal implant positioning and placement for each individual patient. Currently the following physicians are credentialed to offer the MAKOplasty® procedure at TGH: Dr. Thomas Bernasek, Dr, Kenneth Gustke, Dr. Grant Garlick and Dr. Steven Lyons – all orthopaedic surgeons with the Florida Orthopaedic Institute in Tampa.
