Cutting and implanting errors in minimally invasive total knee arthroplasty using a navigation system

A new navigation system for minimally invasive total knee arthroplasty.

A computer-assisted navigation system to be used for total knee arthroplasties (TKAs) was reported to improve the accuracy of bone resection and result in precise implant placement, but the concomitant surgical invasion and time consumption are clinical problems. We developed a computed tomography (CT)-based navigation system (NNS) to be used for minimally invasive TKA. It requires only the ref...

Walking and Stair Descent Following Minimally Invasive Total Knee Arthroplasty

Introduction: Total knee arthroplasty (TKA) is a surgery commonly used to relieve the pain caused by osteoarthritis at the knee joint. Previous studies have shown patients with degenerative joint disease walk more slowly than normal subjects due to decreases in stride length and cadence (Stauffer et al. 1977). Falls on stairs are a leading cause of injury in older adults (Starzell, et al., 2000...

Midterm outcomes of electromagnetic computer-assisted navigation in minimally invasive total knee arthroplasty

BACKGROUND A combination of two emerging technologies, computer-assisted navigation and minimally invasive surgery, in total knee arthroplasty has gained increasing interests from orthopedic surgeons around the world. To date, there has never been any midterm study for clinical and radiographic outcomes from using an electromagnetic computer-assisted navigation system. In this study, we aimed t...

Navigation in Total Knee Arthroplasty

Navigation was the most significant advance in instrumentation for total knee arthroplasty over the last decade. It provides surgeons with a precision tool for carrying out surgery, with the possibility of intraoperative simulation and objective control over various anatomical and surgical parameters and references. Since the first systems, which were basically used to control the alignment of ...
