Realignment osteotomies around the knee joint are used primarily for management of arthritis. Traditionally, an unstable knee has been considered a contraindication for osteotomy. But with a better understanding of biomechanics of osteotomies and their effect on ligament instabilities, the beneficial role of osteotomies in managing an unstable knee is becoming clearer. This review looks at recent literature on this subject to help in formulating a management plan especially in failed ligament reconstruction patients.

Background: The diagnosis of syndesmotic instability is challenging, and chronically unstable injuries can potentially lead to ankle arthritic degeneration. The objective of this cadaveric study was to utilize a 3-dimensional (3D) weight-bearing computed tomography (WBCT) distance mapping algorithm for the detection of subtle syndesmotic instability, induced by complete syndesmotic ligament sectioning and stressed by isolated axial load. We hypothesized that this algorithm would accurately detect subtle syndesmotic instability.

Voluntary breathing (VB), short-term exercise (STE), and mental stress (MS) can modulate breathing rate (BR), heart rate (HR), and blood pressure (BP), thereby affecting human physical and mental state. While existing experimental studies have explored the relationship between VB, STE, or MS and BR, HR, and BP changes, their findings remain fragmented due to individual differences and challenges in simultaneous, BR, HR, and BP measurements. We propose a computational approach for in-silico simultaneous measurements of the physiological values by comprehensive prediction of the respiratory and circulatory system responses to VB, STE, or MS.

Background: Core muscles serve as a central group within the functional kinetic chain, stabilizing the spine during movement. The Reformer is one of the most popular and primary pieces used in Pilates core exercises, requiring effective control of core muscles. The purpose of this study was to investigate the effect of Reformer spring resistance on core muscle activity.

Introduction: Patellar instability is a multifactorial pathology requiring precise evaluation of its contributing factors, particularly patella alta. Patellotibial height measurement indexes, such as the Caton-Deschamps index, have the disadvantage of being referenced to the tibia. Patellotrochlear indexes are more appropriate but fail to account for variable knee flexion during magnetic resonance imaging (MRI).

Introduction: Delayed union, non-union, and unstable fixation can lead to fatigue fractures of orthopedic implants. Breakages typically occur at the fracture site or locking screw insertion, acting as stress concentration foci. This case report highlights a rare instance of a 3-part broken proximal femoral nail (PFN), extracted using a corticotomy-assisted method without knee joint violation.
