The advent of computer-assisted knee replacement surgery has focused interest on the
alignment of the components. However, there is confusion at times between the alignment of …

Computer assisted surgery (CAS) was used to improve the positioning of implants during
total knee arthroplasty (TKA). Most studies have reported that computer assisted navigation …

Background: The purpose of this study was to determine the effect of tibiofemoral alignment,
femoral and tibial component alignment, and body-mass index (BMI) on implant survival …

After obtaining informed consent, 80 patients were randomised to undergo a navigated or
conventional total knee replacement. All received a cemented, unconstrained, cruciate …

BACKGROUND: The mechanical alignment of the knee is an important factor in planning for,
and subsequently assessing the success of a knee replacement. It is most commonly …

This investigation evaluated the Smith and Nephew VISIONAIRE patient-specific cutting
block (PSCB) system for total knee arthroplasty. A consecutive series of 60 patients was …

Background This pilot study was performed to examine the accuracy of the AR-KNEE
system, an imageless navigation system using augmented reality (AR) technology for total …

Precise pre-and postoperative anatomic measurements are necessary to plan, perform, and
evaluate total knee arthroplasty (TKA). We evaluated the relationship between radiographic …

Background Previously published studies reported benefits of computer-assisted surgery
(CAS) in terms of radiographic implant position in TKA, but whether these improvements …

In computer-assisted TKA, surgeons determine positioning of the femoral component in the
sagittal plane based on the sagittal mechanical axis identified by the navigation system. We …
