Rotational Instability in Superlubric Joints [PDF]

Physical Review Letters, 2019
Surface and interfacial energies play important roles in a number of instability phenomena in liquids and soft matters, but are rare to play a similar role in solids. Here we report a new type of mechanical instabilities that are controlled by surface and interfacial energies and are valid for a large class of materials, in particular two-dimensional ...

Mouse model of subtalar post-traumatic osteoarthritis caused by subtalar joint instability

Journal of Orthopaedic Surgery and Research, 2022
Background Common ankle sprains are often accompanied by injury to the subtalar joint, which eventually leads to subtalar joint instability. Because the clinical manifestations for subtalar joint instability are similar to ankle joint injuries, these are

Effects of exercise therapy on joint instability in patients with osteoarthritis of the knee: A systematic review

Osteoarthritis and Cartilage Open, 2020
Summary: Objective: Abnormal load stress caused by joint instability has been reported to be one of the factors responsible for the development of osteoarthritis (OA).

Distal Clavicular Augmentation with Acromioclavicular and Coracoclavicular Ligament Reconstruction in the Setting of Iatrogenic Induced Acromioclavicular Instability

Arthroscopy Techniques, 2019
Although chronic pain and dysfunction of the acromioclavicular (AC) joint can reliably be treated with distal clavicle excision, disruption of the local stabilizing ligamentous structures may result in iatrogenic instability of the joint.

Ultrasound Imaging of Subtalar Joint Instability for Chronic Ankle Instability. [PDF]

Healthcare (Basel), 2023
The purpose of this study was to develop the assessment of subtalar joint instability with chronic ankle instability (CAI) using ultrasonography. Forty-six patients with anterior talofibular ligament (ATFL) abnormalities and a history of ankle sprain ...

Management of Instability following Pyogenic Sacroiliitis: Technical Case Report

Case Reports in Orthopedics, 2020
Background. Septic arthritis of the sacroiliac joint (SI-joint) is a rare and often delayed diagnosis. Management usually consists of intravenous antibiotics and debridement of infected tissue.

Current concepts in acromioclavicular joint (AC) instability – a proposed treatment algorithm for acute and chronic AC-joint surgery

BMC Musculoskeletal Disorders, 2022
Background There exists a vast number of surgical treatment options for acromioclavicular (AC) joint injuries, and the current literature has yet to determine an equivocally superior treatment.

Restoring Horizontal Stability of the Acromioclavicular Joint: Open Acromioclavicular Ligament Reconstruction and Repair With Semitendinosus Allograft

Arthroscopy Techniques, 2020
Injuries to the acromioclavicular (AC) joint are common and comprise ∼12% of shoulder injuries. Stability to the AC joint depends on the coracoclavicular (CC) ligaments for vertical stability and AC ligaments and capsular structures for horizontal ...

Comparable in vivo joint kinematics between self-reported stable and unstable knees after TKA can be explained by muscular adaptation strategies: A retrospective observational study

eLife, 2023
Background: Postoperative knee instability is one of the major reasons accounting for unsatisfactory outcomes, as well as a major failure mechanism leading to total knee arthroplasty (TKA) revision.

Multidirectional Instability in a Neglected Elbow Dislocation Managed with Circumferential Ligament Reconstruction. A Case Report

Revista Brasileira de Ortopedia, 2023
Neglected elbow dislocation is an uncommon condition and its treatment remains challenging. We present a case of a middle-aged woman presenting with neglected elbow dislocation and multi-direction instability in whom open reduction of the elbow joint and
