Loosening of the anterolateral capsule affects the stability after arthroscopic lateral ankle ligament repair of chronic ankle instability.
Arthroscopic anterior talofibular ligament (ATFL) repair for chronic lateral ankle instability (CLAI) has been widely performed. The recurrence of the instability after the surgery sometimes occurs, which may cause the development of osteoarthritis. Therefore, it is important to elucidate the factors of the recurrence. This study aimed to evaluate the loosening of the capsule in the MRI and whether it affected clinical outcomes or not in arthroscopic ATFL repair. ⋯ Capsule loosening would be one of the causes of the recurrence of instability after arthroscopic lateral ankle ligament repair. Evaluation of the capsule protrusion area on MRI is helpful to choose appropriate surgical procedures for CLAI patients.

Are there associations between hip geometry and bone quality? An analysis on 3074 adults from a general population.
Patients with reduced bone mineral density and altered hip geometry are susceptible for hip pathologies. Knowledge on associations between bone properties and hip geometric parameters might facilitate identification of patients at risk for hip pathologies. The aim of the present study was to identify associations of bone properties assessed by quantitative ultrasound (QUS) at the heel and hip geometric parameters like center-edge angle (CE), neck-shaft angle (NSA) and alpha angle. ⋯ In the general population, several associations between QUS-based bone properties or fracture risk and hip geometry are present. Less dysplastic hips had a lower stiffness-index and a higher fracture risk, whereas more valgus hips had a lower fracture risk.

Maintenance of the joint line and posterior condylar offset are the most notable variables for successful outcomes of revision total knee arthroplasty.
Controversy regarding which variables should be prioritized for better outcomes in revision total knee arthroplasty (RTKA) exists. This study aimed to comprehensively analyze the variables affecting RTKA outcomes. ⋯ Level III, cohort study.

Precontoured dynamic compression plate using patient-specific 3D-printed models in minimally invasive surgical technique for midshaft clavicle fractures.
This study introduced a novel approach for the treatment of midshaft clavicle fractures, utilizing patient-specific 3D-printed models for accurate preoperative contouring of dynamic compression plates (DCPs) and an alternative minimally invasive plate osteosynthesis (MIPO) technique with precontoured DCPs through small vertical separated incisions. ⋯ Our study demonstrated that the use of a patient-specific precontoured DCP, in combination with 3D printing technology, provides accurate preoperative planning, effective fracture reduction, and improved postoperative outcomes in displaced midshaft clavicle fractures. The MIPO with a patient-specific precontoured DCP through separated vertical incisions along the Langer's lines appears to be a promising option, regarding appearance, avoiding associated complications, and obviating the need for reoperation. These results suggest that this technique has merit and can be a viable option for the treatment of midshaft clavicle fractures.

Analysis of acute extremity compartment syndrome using a genealogic population database.
Acute extremity compartment syndrome ("CS") is an under-researched, highly morbid condition affecting trauma populations. The purpose of this study was to analyze incidence rates and risk factors for extremity compartment syndrome using a high-quality population database. Additionally, we evaluated heritable risk for CS using available genealogic data. We hypothesized that diagnosis of extremity compartment syndrome would demonstrate heritability. ⋯ III.
