Roentgen stereophotogrammetric analysis as a predictor of mechanical loosening of knee prostheses
Leif Ryd,Björn E.J. Albrektsson,Lars Carlsson,F. Dansgard,P. Herberts,Anders Lindstrand,L. Regner,Sören Toksvig-Larsen +7 more
TL;DR: Findings suggest that mechanical loosening begins early in the postoperative period, seen at this stage in 20% of abnormally migrating tibial components, may not appear until up to ten years after the operation.
Journal ArticleDOI
Guidelines for standardization of radiostereometry (RSA) of implants
TL;DR: 6 research centers have agreed upon standards for terminology, description and use of RSA arrangement including radiographic set-up and techniques, which will form the basis of a detailed standardization protocol under supervision of ISO and the European Standards Working Group on Joint Replacement Implants.
Journal ArticleDOI
Appropriate questionnaires for knee arthroplasty. Results of a survey of 3600 patients from The Swedish Knee Arthroplasty Registry
TL;DR: In this article, the authors tested various outcome questionnaires in order to determine which is the best for patients who have had knee arthroplasty as applied in a cross-sectional, discriminative, postal survey.
Journal ArticleDOI
Wear in retrieved condylar knee arthroplasties: A comparison of wear in different designs of 280 retrieved condylar knee prostheses
Gordon Blunn,Atul B. Joshi,R.J. Minns,Lars Lidgren,P. Lilley,Leif Ryd,E. Engelbrecht,Peter S. Walker +7 more
TL;DR: The plastic components of 280 retrieved unicondylar and total knee arthroplasties were studied and delamination was the principal were type and that the incidence of failure could accelerate considerably over follow-up periods beyond 10 years.
Journal ArticleDOI
Increased levels of proteoglycan fragments in knee joint fluid after injury
TL;DR: Levels of cartilage proteoglycan fragments in knee joint synovial fluid obtained from patients with previous trauma of the knee, early gonarthrosis, or pyrophosphate synovitis are measured and may be a marker for early posttraumatic arthrosis.
