The COVID-19 pandemic has disrupted the provision of arthroplasty services in England, Wales, and Northern Ireland. This study aimed to quantify the backlog, analyze national trends, and predict time to recovery. We performed an analysis of the mandatory prospective national registry of all independent and publicly funded hip, knee, shoulder, elbow, and ankle replacements in England, Wales, and Northern Ireland between January 2019 and December 2022 inclusive, totalling 729,642 operations. The deficit was calculated per year compared to a continuation of 2019 volume. Total deficit of cases between 2020 to 2022 was expressed as a percentage of 2019 volume. Sub-analyses were performed based on procedure type, country, and unit sector.Aims
Methods
The purpose of this study was to compare the
diagnostic accuracy for the detection of infection between the culture of
fluid obtained by sonication (SFC) and the culture of peri-implant
tissues (PITC) in patients with early and delayed implant failure,
and those with unsuspected and suspected septic failure. It was
hypothesised that SFC increases the diagnostic accuracy for infection
in delayed, but not early, implant failure, and in unsuspected septic
failure. The diagnostic accuracy for infection of all consecutive
implants (hardware or prostheses) that were removed for failure was
compared between SFC and PITC. This prospective study included 317
patients with a mean age of 62.7 years (9 to 97). The sensitivity
for detection of infection using SFC was higher than using PITC
in an overall comparison (89.9% Sonication is mainly recommended when there is implant failure
with no clear signs of infection and in patients with delayed implant
failure. In early failure, SFC is not superior to PITC for the diagnosis
of infection and, therefore, is not recommended as a routine diagnostic
test in these patients. Cite this article:
