The aims of this study were to: 1) report on a cohort of skeletally mature patients with native hip and knee septic arthritis over a 14-year period; 2) to determine the rate of joint failure in patients who had experienced an episode of hip or knee septic arthritis; and 3) to assess the outcome following septic arthritis relative to the infecting organism, whether those patients infected by All microbiological samples from joint aspirations between March 2000 and December 2014 at our institution were reviewed in order to identify cases of culture-proven septic arthritis. Cases in children (aged < 16 years) and prosthetic joints were excluded. Data were abstracted on age at diagnosis, sex, joint affected (hip or knee), type of organisms isolated, cause of septic arthritis, comorbidities within the Charlson Comorbidity Index (CCI), details of treatment, and outcome.Aims
Methods
The aim of this study was to develop a single-layer hybrid organic-inorganic sol-gel coating that is capable of a controlled antibiotic release for cementless hydroxyapatite (HA)-coated titanium orthopaedic prostheses. Coatings containing gentamicin at a concentration of 1.25% weight/volume (wt/vol), similar to that found in commercially available antibiotic-loaded bone cement, were prepared and tested in the laboratory for: kinetics of antibiotic release; activity against planktonic and biofilm bacterial cultures; biocompatibility with cultured mammalian cells; and physical bonding to the material (n = 3 in all tests). The sol-gel coatings and controls were then tested in vivo in a small animal healing model (four materials tested; n = 6 per material), and applied to the surface of commercially pure HA-coated titanium rods.Aims
Methods
Periprosthetic joint infection (PJI) is a devastating
complication for patients and results in greatly increased costs
of care for both healthcare providers and patients. More than 15
500 revision hip and knee procedures were recorded in England, Wales
and Northern Ireland in 2013, with infection accounting for 13%
of revision hip and 23% of revision knee procedures. We report our experience of using antibiotic eluting absorbable
calcium sulphate beads in 15 patients (eight men and seven women
with a mean age of 64.8 years; 41 to 83) as part of a treatment
protocol for PJI in revision arthroplasty. The mean follow-up was 16 months (12 to 22). We report the outcomes
and complications, highlighting the risk of hypercalcaemia which
occurred in three patients. We recommend that serum levels of calcium be routinely sought
following the implantation of absorbable calcium sulphate beads
in orthopaedic surgery. Cite this article:
Biofilm-associated infections in wounds or on implants are difficult to treat. Eradication of the bacteria is nearly always impossible, despite the use of specific antibiotics. The bactericidal effects of high-energy extracorporeal shock waves on The biofilm-cultured washers were exposed to low-energy shock waves at 0.16 mJ/mm2 for 500 impulses. The washers were then treated with cefuroxime, rifampicin and fosfomycin, both alone and in combination. All tests were carried out in triplicate. Viable cells were counted to determine the bactericidal effect. The control groups of We conclude that shock waves combined with antibiotics could be tested in an
