Outcomes-based evaluations supporting computer-assisted surgery and minimally invasive surgery for total hip arthroplasty.
Minimally invasive surgeries, as well as computer-assisted surgery for total hip replacement have gained popularity over recent years. This article provides an overview of state-of-the-art minimally invasive surgery (MIS) and computer-assisted surgery for total hip arthroplasty. A comprehensive review of the literature for scientific evidence supporting the use of these technologies was undertaken. This review evaluates whether commonly asked questions concerning these topics have been addressed. Controversy remains as to whether there are significant benefits of MIS or computer-assisted surgery for total hip arthroplasty. Fortunately, most studies report similar outcomes for both technologies. Minimally invasive techniques have been developed that do not significantly increase operative time or immediate postoperative complications. Computer-assisted navigation has shown improved radiographic alignment for total hip arthroplasty and may allow MIS to be performed more optimally. The authors believe that both of these technologies are likely to have a place in the future for hip arthroplasty with expectations of increased successful outcomes with these techniques while lowering complications and costs. Long-term outcomes of both techniques will need to be investigated.
