An increased medial proximal tibial angle of greater than 95 degrees after opening wedge high tibial osteotomy is not associated with deterioration of minimum 10-year clinical outcomes.
The purpose of this study was to assess whether an excessively increased medial proximal tibial angle (MPTA) resulted in the deterioration of long-term clinical outcomes after opening wedge high tibial osteotomy (OWHTO) for patients with knee osteoarthritis (OA). ⋯ Increased MPTA > 95° after OWHTO is not associated with deterioration of minimum 10-year clinical outcomes.

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.

Timing of surgery for spinal deformity patients during the COVID‑19 pandemic: experience from a prospective cohort at Peking Union Medical College Hospital.
The purpose of this study was to explore the optimal timing and associated risks of spinal deformity surgery during the COVID‑19 pandemic. ⋯ With careful preoperative screening of patients for COVID-19, spinal deformity surgery can proceed safely during the epidemic. We recommend that spinal deformity surgery be delayed in patients with COVID-19 until 8 weeks after SARS-CoV-2 infection.

Elevated body mass index and obesity are associated with pain-associated psychological distress in patients with hip pain.
Little research has investigated the relationship between musculoskeletal pain and body mass index (BMI) in the context of pain-associated psychological distress. This study aims to determine if independent associations exist between BMI, obesity, demographic variables, and psychological distress in patients presenting with hip pain. ⋯ Elevated BMI and obesity are associated with high psychological distress in patients with hip pain. These results may inform operative, nonoperative, and behavioral health treatment pathways for patients with comorbid obesity and hip pain, as well as provide direction for prospective studies to address obesity and psychological distress among patients with musculoskeletal pain.

A new classification system for distal clavicle fractures: based on fracture location and ligament integrity.
Although various classification systems have been introduced for the description of distal clavicle fractures, there is no consensus on the best classification system that is helpful in determining treatment and prognosis. The objective of this study was to establish a new classification system for distal clavicle fractures and to verify the reliability of the new classification system by evaluating the inter- and intraobserver agreement. ⋯ The new classification system which takes into account fracture location and ligament integrity brought few disputes in category division and treatment selection.
