Introduction: Throughout surgical and invasive procedures, reusable instruments and flexible endoscopes become soiled with organic and inorganic materials. When these substances are permitted to dry, a matrix of microbial cells, called biofilm, forms on the surface of devices, irreversibly binding and subsequently impeding the disinfection and sterilization process. To prevent biofilm formation from occurring, devices must be continuously flushed and wiped with water throughout the procedure and at the end of the case.

This is the first known study to examine utilization and complications in poorly studied minority racial groups such as Asians and Native Hawaiian/Pacific-Islanders (NHPI) as compared to Whites.
Results: Data from 3304 primary total hip and knee arthroplasty patients (2011 to 2019) were retrospectively collected, involving 1789 Asians (52.
Article Synopsis
- The study investigates whether significant patellofemoral arthritis (PFA) affects post-operative outcomes after unicondylar knee arthroplasty (UKA), focusing on knee range of motion and functional scores within the first six months.
- It analyzed data from 323 patients who underwent UKA from 2015 to 2019, categorizing them based on the severity of PFA at the time of surgery into three groups.
- Results indicated that while patients with severe PFA had lower pre- and post-operative knee flexion, there were no significant differences in functional improvement across the groups, with age and body mass index being notable factors influencing knee flexion outcomes post-surgery.
Preoperative arthroplasty classes decrease complications and readmissions, however, in-person classes are inconvenient for elderly patients with mobility limitations. This retrospective review included 232 patients (305 joints) with in-person preoperative educational classes (IPC) and 155 patients (192 joints) with telephone preoperative educational classes (TC). Compared to IPC, TC patients had a shorter length of stay (P<.

- The study investigates how body mass index (BMI) affects the accuracy of acetabular cup placement during total hip arthroplasty (THA) when using intra-operative fluoroscopy (IF) alone or with additional guidance technologies.
- Results show that higher BMI is linked to increased abduction angle and anteversion differences when using IF alone, but guidance technologies like Overlay and Digital improved placement accuracy regardless of BMI.
- Overall, morbid obesity (BMI > 35) was found to increase the risk of malpositioning and surgical time, emphasizing the benefits of using advanced imaging technology during surgery.
