Joint replacement surgery has become one of the most common types of surgery performed at Beth Israel Deaconess - Plymouth. Advances in orthopedic implants and surgical techniques have greatly reduced recovery times for patients undergoing joint replacement. An exciting new technique known as computer-assisted minimally invasive surgery, or MIS, is being used for hip and knee replacement with considerable success.
MIS surgery uses a smaller incision than conventional surgery. In some MIS procedures, the amount of soft tissue (muscles and tendons, etc) that is disrupted during surgery may also be reduced. Even though MIS procedures have been used for many other surgical areas including cardiac, gall bladder and spinal surgery, MIS is a relatively new development for joint replacement.
In terms of hip surgery, the navigation system allows the physician to be incredibly accurate in terms of positioning the hip, which results in precise control of leg length, and better range of motion post-surgery.
The computerized navigation system uses an infrared camera and markers along with unique instrument tracking software to continually monitor the position and mechanical alignment of the implant components based on the patient’s anatomy. It provides the surgeon with a comprehensive understanding of the patient’s hip mechanics before any bone is cut. Wireless “smart” instruments send the data pertaining to the hip kinematics (movements) to a computer.
