Dr.Giles R. Scuderi, in an online publication, August 2011, reported that between May 2001 and June 2004, 388 total knee arthroplasty cases were enrolled in a prospective, randomized, multicenter investigational device exemption trial. Patients received either the investigational high-flexion mobile-bearing knee or a fixed-bearing control. At 2 to 4 years of follow-up, results in 293 patients with degenerative joint disease were compared using Knee Society Assessment and Function scores, radiographic results, complications analysis, and survival estimates. The mobile-bearing and fixed-bearing groups demonstrated similar, significant improvement over preoperative assessments in Knee Scores, maximum flexion, and range of motion. One mobile-bearing arthroplasty required revision. Radiographic results were unremarkable, and implant-related complications were rare in both groups. At this early follow-up, the investigational high-flexion mobile-bearing knee and its fixed-bearing counterpart demonstrated comparable, effective performance.
Post knee surgery physical therapy received a major boost with the advent of the LegTutor. This is a new device that improves fine motor, sensory and cognitive impairments through intensive active exercises with augmented feedback. The repetitive training is tailored to patient performance and allows the therapist to customize the most suitable rehabilitation program to the patient’s ability. The LegTutor together with its sisters the HandTutor, ArmTutor and 3DTutor are currently in use in major U.S. and foreign hospitals. Used in private clinics and even at home with tele rehabilitation the Tutors are successful for children as well as adults.
