We reviewed the records and radiographs of 387 cemented revisions of aseptic loose sockets after total hip replacement at a mean follow-up of 5.5 years. The clinical results were satisfactory, but at the last radiological assessment 38 sockets (9.8%) had a continuous zone of demarcation greater than 1 mm thick and another 35 (9%) showed migration. Poor acetabular bone stock had a profound influence on the outcome of revision surgery, but the results of cemented revision were comparable to those reported for cementless revision at similar mean follow-up.

Background: Two-stage revision is known as the gold-standard method for knee prosthetic joint infection (PJI), but the most suitable treatment method remains controversial. Typically, weight-bearing is restricted during the interval between the stages. The aim of this study was to evaluate the clinical outcomes of unrestricted weight bearing with cement spacers fabricated using the Knee Articulating Spacer Mold (KASM®; Ortho Development Corporation, Draper, UT, USA) for knee PJI.

Purpose: The study aimed to compare the infection control rates, mechanical complications, and functional outcomes between prosthetic and cement spacers in two-stage revision arthroplasty for chronic periprosthetic joint infection (PJI).
Patients And Methods: Data from patients treated for chronic PJI in our center from 2014 to 2023 were retrospectively collected and the patients were divided into the prosthetic spacer (PS) and cement spacer (CS) groups based on the type of spacer used for the first-stage surgeries. Data on patients' demographics and clinical scores were harvested.

Background And Purpose: This study updates 2 parallel systematic reviews and meta-analyses from 2012, which established the 1-year radiostereometric (RSA) migration thresholds for tibial components of total knee replacements (TKR) based on the risk of late revision for aseptic loosening from survival studies. The primary aim of this study was to determine the (mis)categorization rate of the 2012 thresholds using the updated review as a validation dataset. Secondary aims were evaluation of 6-month migration, mean continuous (1- to 2-year) migration, and fixation-specific thresholds for tibial component migration.

Objective: Transcutaneous osseointegration prosthetic systems (TOPS) offer a stable skeletal attachment for artificial limbs post-extremity amputation, serving as an alternative to socket attachment. Press-fit osseointegration implants (OI) utilized in TOPS consistently enhance quality of life and mobility for amputees, particularly those experiencing socket-related issues. Despite notable benefits, late complications such as infection and implant loosening pose challenges unique to TOPS due to their percutaneous nature.

: Vancomycin is commonly used in the treatment of periprosthetic joint infection (PJI), and trough concentrations are measured to ascertain that they are within the therapeutic range. It has not been investigated what proportion of vancomycin concentrations during treatment of PJI patients is accurately within this range, how many dose adjustments are commonly needed, and which patient factors predispose towards aberrations from the desired range. : In this single-center cohort study, we investigated vancomycin trough concentrations in 108 patients with surgically treated PJI who received IV administered vancomycin treatment post-operatively.
