The aim of this study was to obtain, using Magnetic Resonance Imaging (MRI), muscle volume measurements for the gluteus maximus (upper: UGM and lower: LGM portions) and tensor fascia lata (TFL) muscles in both healthy subjects (n=12) and those with unilateral osteoarthritis (OA) of the hip (mild: n=6, and advanced: n=6). While control group subjects were symmetrical between sides for the muscles measured, subjects with hip joint pathology showed asymmetry in GM muscle volume dependent on stage of pathology. The LGM demonstrated atrophy around the affected hip in subjects with advanced pathology (p<0.05), however asymmetry of the UGM (p<0.01) could be attributed largely to hypertrophy on the unaffected side, based on between group comparisons of muscle volume. TFL showed no significant asymmetry, or difference compared to the normal control group. This study highlights the functional separation of UGM and LGM, and the similarities of the UGM and TFL, both superficial abductors appearing to maintain their size around the affected hip. Further research is required to determine the specific changes occurring in the deeper abductor muscles. This information may assist in the development of more targeted and effective exercise programmes in the management of OA of the hip.

Introduction: In 2020, 368 million people globally were affected by knee osteoarthritis, and prevalence is projected to increase with 74% by 2050. Relatively high rates of dissatisfactory results after total knee arthroplasty (TKA), as reported by approximately 20% of patients, may be caused by sub-optimal knee alignment and balancing. While mechanical alignment has traditionally been the goal, patient-specific alignment strategies are gaining interest.

Purpose: This study aimed to explore the association and prediction of hip abduction-adduction and knee flexion-extension isokinetic absolute and relative strength and power at 60°/s and 180°/s from functional tests performance (i.e., Up-and-Go Test [seconds], 30-Second Chair Stand Test [repetitions and relative and allometric power], 30-Second Arm Curl Test [repetitions], and 6-Minute Walk Test [meters]) in older adults.

Introduction: Patients who have poorly controlled diabetes mellitus are at increased risk of periprosthetic joint infection (PJI). Nevertheless, an optimal preoperative hemoglobin A1c (HbA1c) threshold has not been established. This study sought to identify preoperative HbA1c thresholds that were predictive of adverse outcomes for total hip (THA) and total knee arthroplasty (TKA) patients.

Background: The gluteus medius and minimus muscles play a critical role in hip biomechanics, however there is a paucity of literature examining the impact of preoperative gluteal pathology on outcomes following total hip arthroplasty (THA). This study compared pain, satisfaction, and functional outcomes among patients who had and did not have preoperative gluteal pathology after direct anterior (DA) THA.
Methods: Using an institutional total joint registry, patients undergoing DA THA for osteoarthritis between 2010 and 2022 were retrospectively reviewed.

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.
Background: Fractures of the thoracic and lumbar spine are increasingly common. Although it is known that such fractures may elevate the risk of near-term morbidity, the natural history of patients who sustain such injuries remains poorly described. We sought to characterize the natural history of patients treated for thoracolumbar fractures and to understand clinical and sociodemographic factors associated with survival.
