The AES total ankle replacement: A mid-term analysis of 93 cases.

Background: There are few studies concerning specific total ankle arthroplasties. This study reports mid-term survival data for the AES prosthesis.

Methods: Ninety-three AES ankle arthroplasties were performed by the senior authors.

Microbiology of the infected knee arthroplasty: report from the Swedish Knee Arthroplasty Register on 426 surgically revised cases.

Surgically revised deep infected primary knee arthroplasties reported to the Swedish knee arthroplasty register during the years 1986-2000 were studied with respect to microbiology, antimicrobial susceptibility pattern and changes over time. In early, delayed and late infections, coagulase-negative staphylococci (CoNS) were most prevalent (105/299, 35.1%), and twice as common as Staphylococcus aureus (55/299, 18.

Revision in previously satisfied knee arthroplasty patients is the result of their call on the physician, not on pre-planned follow-up: a retrospective study of 181 patients who underwent revision within 2 years.

Background: Degree of satisfaction with a knee arthroplasty is said to be correlated to reduced pain and better function. During a validation of the Swedish Knee Arthroplasty Register in 1997, previously operated patients were asked how satisfied they were with their knee. A subgroup of "satisfied" patients was identified who underwent revision within 2 years of having expressed satisfaction.

Infection and arthritis. Infection of prosthetic joints.

Infection of prosthetic joints is one of the most devastating complications following replacement surgery. The size of the problem, the diagnostic puzzle, bacteriological findings and treatment modalities are highlighted.
