Article Synopsis
- Proximal femoral fractures have plateaued or decreased despite an aging population, with expectations of rising cases due to increased life expectancy.
- A study comparing patients from 2000-2001 to 2020-2021 found that average age increased from 71.6 to 79.0 years, while hospital stays significantly decreased from an average of 15.1 days to 6.0 days.
- Complication rates and mortality remained similar between both time periods, suggesting that quicker discharges could be beneficial for elderly patients while maintaining individualized care plans.
Ipsilateral pubic ramus fracture during total hip arthroplasty is not rare: does it matter?

Article Synopsis
- - The study investigates the occurrence of ipsilateral pubic ramus fractures during total hip arthroplasty (THA), which are often asymptomatic and have been understudied until now.
- - Out of 203 THAs performed, 22 cases (10.8%) of these fractures were identified through postoperative CT scans, mostly near the superior or inferior pubic ramus; they presented no significant complications during the six-month follow-up.
- - Despite the high incidence, no specific risk factors were found, and treatment isn't necessary since these fractures don't impact THA outcomes, but patients should be informed about their potential occurrence prior to surgery.
Background: In metaphyseo-diaphyseal (M-D) mismatched Dorr A femurs, it is difficult to achieve proper fixation with a type 1 stem. Proper interpretation of the geometry of the femur is integral at the preoperative stage in an M-D mismatched femur, but there has been a scarcity of studies on the radiologic indices. Therefore, we analyze the previous radiologic indices and suggest the novel ones for M-D mismatched femurs.

Previously, several risk factors have been suggested, but they were subjected to their inherent limitations. By controlling confounding variables, we hypothesized that known risk factors be re-evaluated and novel ones be discovered.

After the report, we abandoned the use of MoP; instead, we used ceramic-on-ceramic (CoC) bearing. This report aimed to present the outcome of reoperation to CoC bearing after ceramic component failures along with the longer-term outcome of the previously reported cohort with an MoP bearing.

This study aimed to determine the efficacy of administration on 1 day postoperatively.
Methods: Patients who were scheduled to undergo TKA were randomly assigned to the following groups: control group, receiving normal saline injection; group 1, receiving 10 mg dexamethasone intravenously (IV) 1 hour before surgery; group 2, receiving 0.
Purpose: Recently, the Persona total knee arthroplasty (TKA) system with more anatomical features and a similarly high flexion to the previous version, LPS-Flex, was introduced and is widely used. This study aimed to compare the early outcomes obtained using Persona versus an LPS-Flex fixed PS implant.
Methods: A total of 784 knees that underwent primary TKAs (162: Persona group and 622: LPS-Flex group) were included.
