Biomechanical and Functional Improvements Gained by Proximal Tibia Osteotomy Correction of Genu Varum in Patients with Knee Pain.

Background: Mechanical axis malalignment contributes to abnormal forces across the knee joint. Genu varum, or increased medial mechanical axis deviation (MAD), increases force transmission and contact pressures to the medial compartment. With increasing MAD and femoral-tibial mechanical axis angle (MAA), contact forces within the medial or lateral compartment of the knee significantly increase with increasing deformity.

Assessment of Various Measurement Methods to Assess First Metatarsal Elevation in Hallux Rigidus.

Background: While metatarsus primus elevatus (MPE) has been implicated in the development of hallux rigidus, previous studies have presented conflicting findings regarding the relationship between MPE and arthritis. This may be due to the variety of definitions for MPE and the radiographic measurement techniques that are used to assess it. Additionally, previous studies have only assessed elevation of the first metatarsal with respect to the floor or the second metatarsal, and not with respect to the proximal phalanx.

Return to Sports and Physical Activities After First Metatarsophalangeal Joint Arthrodesis in Young Patients.

Background: Arthrodesis of the first metatarsophalangeal (MTP) joint has been shown to be effective in alleviating pain and correcting deformity in hallux rigidus. However, outcomes in specific sports and physical activities remain unclear. The aim of this study was to assess sports and physical activities in young patients following first MTP joint arthrodesis and to compare these results with clinical outcomes.

Ankle Arthroscopy for Diagnosis of Full-thickness Talar Cartilage Lesions in the Setting of Acute Ankle Fractures.

Purpose: To delineate the prevalence of chondral lesions, in particular full-thickness talar dome lesions, with concurrent arthroscopy in acute ankle fracture open reduction-internal fixation (ORIF) and evaluate the impact on clinical outcomes.

Methods: We conducted a retrospective chart review of prospectively collected registry data at our institution from 2012 to 2016. Consecutive patients who underwent acute ankle fracture ORIF with concurrent arthroscopy were identified.

Intraoperative skull-femoral traction in posterior spinal arthrodesis for adolescent idiopathic scoliosis: the impact on perioperative outcomes and health resource utilization.

Study Design: Retrospective, single-center cohort study.

Objective: To study how the systematic use of intraoperative skull-femoral traction (IOSFT) in posterior arthrodesis for adolescent idiopathic scoliosis impacts perioperative outcomes and health resource utilization.

Summary Of Background Data: Large scoliosis curves have been associated with increased morbidity and utilization of health resources.
