Validation of the in vivo volumetric wear measurement for total knee prostheses in model-based RSA

Implant failure related to polyethylene wear remains an important issue in total knee arthroplasty. Polyethylene wear is usually assessed in vivo by measuring the remaining insert thickness on X-ray images of the knee. To reflect the amount of wear debris more accurately, a 3-dimensional overlap measurement has been suggested, which is based on...

AQUILA: Assessment of quality in lower limb arthroplasty. An expert Delphi consensus for total knee and total hip arthroplasty

Background: In the light of both the importance and large numbers of case series and cohort studies (observational studies) in orthopaedic literature, it is remarkable that there is currently no validated measurement tool to appraise their quality. A Delphi approach was used to develop a checklist for reporting quality, methodological quality...
