Yersinia enterocolitica is a very common organism which is mainly associated with gastrointestinal symptoms. It has not previously been associated with early or late infection of a prosthetic joint replacement. We report a case of late infection, seven years after an uncomplicated knee replacement. This case demonstrates the ability of the organism to breach the joint capsule. There may well be...

Bone Joint J 2013;95-B, Supple A:124–8. Received 7 September 2013; Accepted after revision 8 September 2013 Isolated patellofemoral arthritis is a common condition and there are varying opinions on the most effective treatments. Non-operative and operative treatments have failed to demonstrate effective long-term treatment for those in an advanced stage of the condition. Newer designs and incre...

BACKGROUND Surface replacement arthroplasty is a reconstructive alternative for the treatment of pain and deformity due to osteoarthritis and rheumatoid arthritis of the proximal interphalangeal joint of the finger. This retrospective study was performed to examine long-term outcomes of proximal interphalangeal joint prosthetic surface replacement with a proximal cobalt-chromium (CoCr) and dist...

A new Stratified Approach For Enhanced Reliability (SAFER) pre-clinical simulation testing of joint prostheses is presented in this article. The aim of this approach is preclinical systematic testing of wear performance in the much wider envelope of conditions found clinically rather than relying only on the standard testing conditions that are currently used. The approach includes variations i...

OBJECTIVES The aim was to study the incidence of joint replacements among biologic drug and disease-modifying anti-rheumatic drug (DMARD) users as well as to investigate the plausible effect of biologic treatment on survival of prostheses in patients with Rheumatoid arthritis (RA). METHODS The study population comprised 2 cohorts of patients [Register of biologic treatment in Finland (ROB-FIN...

The morphometric parameters of the head radial bone are relevant for manufacture its prostheses, often in literature only average sizes given without taking into account individual characteristics their ratios. With insufficiently accurate selection used prosthesis radius, complications arise. To prevent development complications, size implant must exactly match anatomical shape and proximal ep...

The long-term biological effects of wear debris are unknown. We have investigated whether there is any evidence of cumulative mutagenic damage in peripheral blood lymphocytes of patients undergoing revision arthroplasty of predominantly metal-on-plastic total hip replacements compared with those at primary arthroplasty. There was a threefold increase in aneuploidy and a twofold increase in chro...

This study aims to evaluate the mechanical performance of a unique, state-of-the-art, patient-specific alloplastic total replacement system for temporomandibular joint that allows enthesis reconstruction developed by CADskills BV (Ghent, Belgium), and its influence on remaining adjacent healthy tissue, looking into magnitude location stresses micromotions. Because reattachment lateral pterygoid...
