Comparative StudyEvaluation of hallux valgus treatment: is classical angular correction approach relevant?
Hallux valgus correction is mostly done by metatarsal procedures, and widely accepted strategy is to decide which surgical method should be used is based on radiological severity using intermetatarsal (IMA) and hallux valgus (HVA) angles (classical angular correction approach-CACA). The aim of the study is to compare the postoperative improvement in radiographic parameters and morphologic appearance of the foot between patients operated with and without adhering to CACA strategy based on classical severity classification using angle measurements. ⋯ III, comparative study.

Assessing the reliability of automated cell count analysis of synovial fluid in the setting of revision total knee arthroplasty.
The diagnostic challenges of periprosthetic joint infection (PJI) for orthopedic surgeons are significant. Prior research has indicated that patients with adverse reactions, dislocations, and aseptic loosening exhibit a heightened count of white blood cells (WBC) in their synovial fluid, along with an increased polymorphonuclear cell percentage (PMN%). The prevalence of false-positive results raises concerns about the reliability of these tools in distinguishing aseptic failure from PJI. ⋯ III.

Mid- to long-term clinical and radiological assessment of a short, titanium, porous plasma-splayed flat-tapered cementless femoral stem: An 8- to 12-year follow-up study.
Short cementless stems offer advantages such as bone-stock preservation and minimally invasive insertion. Despite encouraging short- to midterm outcomes, the long-term clinical and radiological implications of short, titanium, and porous plasma-sprayed flat-tapered stems remain unclear. ⋯ The short, titanium, porous, plasma-sprayed, flat-tapered cementless stem exhibited excellent mid- to long-term results in primary total hip arthroplasties with Dorr type A or B femora, comparable with those of other short cementless and standard-length stems. Noteworthy survivorship was observed; however, caution is advised regarding stress-shielding complications, particularly periprosthetic femoral fractures, during extended follow-up.

Long-term outcomes with a partial neck-preserving cementless short stem in primary total hip arthroplasty for young patients: a single center first one hundred cases.
This study aimed to assess the long-term results of THA patients who received a cementless short stem regarding clinical outcomes, bone changes, complications, and incidence of femoral revision. ⋯ This study showed that the MiniHip short stem is a reliable option for THA in younger patients, with a high implant survival rate and excellent functional outcomes over the long term.

Accuracy of leg length changes in total hip arthroplasty using a computed tomography-based augmented reality navigation system.
Leg length is an important consideration in total hip arthroplasty (THA) as leg length discrepancies (LLD) after THA cause poor outcomes and medical litigation. This study aimed to investigate the accuracy of computed tomography (CT)-based navigation with augmented reality (AR) technology for measuring intra-operative leg length change using anteroposterior radiography (two-dimensional, 2D) and CT (three-dimensional, 3D). ⋯ CT-based navigation with AR technology in the supine position provided acceptable accuracy for leg length change measurements.
