BACKGROUND: Surface translations are a method of perturbing an individual's balance to evoke balance control responses. However, the force plates used to measure kinetic responses often contain artifacts due to inertial properties coupled with the dynamics of surface translation perturbations. Techniques to attenuate these movement artifacts are not well established within the literature. RESEARCH QUESTION: Are amplitude- or frequency-based subtraction processing techniques effective at attenuating inertia-based movement artifacts in kinetic signals during surface translations? METHODS: One-hundred and two backward surface translations were analyzed from five participants...

INTRODUCTION: Osteoarthritis (OA) and rheumatoid arthritis (RA) represent the most common forms of arthritis, which are mainly caused by mechanical and inflammatory components, respectively. Determination of synovial inflammation in synovial biopsies via the histopathological Krenn score may be crucial for correct diagnosis and treatment. Specifically, it remains unclear whether synovitis scores differ among multiple biopsy locations within a single joint. MATERIALS AND METHODS: Eighty synovial samples were taken from four standardized regions of the knee in 20 patients (ten primary OA, ten secondary OA) undergoing total knee arthroplasty (TKA) or total synovectomy...

PURPOSE: Unicompartmental Knee Arthroplasty (UKA) recorded an increased incidence of around 30% per year in the United States. Patient's experience and satisfaction after surgery were traditionally assessed by pre, and post-surgical scores and Patient-Reported Outcome Measures (PROMs) scales. Traditional scales as Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Oxford Knee Score (OKS) reported high ceiling effect. Patients treated by UKA usually perform well; therefore, it is necessary to have a PROMs' scale with a low ceiling effect as the Forgotten Joint Score-12 (FJS-12)...

Effects of low-load blood flow restricted (LL-BFR) training remain unexplored in patients with ACL rupture. Our hypothesis was that LL-BFR training triggers augmented gains in knee muscle strength and size, which are paralleled with transcriptional responses of hypoxia-regulated genes and myokines. Eighteen volunteers (age 37.5 ± 9 yrs.) planned for ACL reconstruction, participated in the study. Twelve were divided between BFR group, performing 9 sessions of LL-BFR exercise, and SHAM-BFR group, performing equal training with sham vascular occlusion...

BACKGROUND: Trochlear dysplasia is highly associated with patellofemoral instability. The goal of conservative and surgical treatment is to stabilize the patella while minimizing adverse effects. However, there is no literature investigating the quantitative influence of different treatment options on patellofemoral stability in knees with trochlear dysplasia. We created and exploited a range of finite element models to address this gap in knowledge. METHODS: MRI data of 5 knees with trochlear dysplasia and symptomatic patellofemoral instability were adapted into this previously established model...

In this article we report a case of stiff, neglected extreme recurvatum knee deformity in a 17-year-old female. This is the first reported case in the literature of an acquired ligamentous stiff extreme knee recurvatum following manipulation under anesthesia and botulinum neurotoxin injection. Μodified Judet quadricepsplasty combined with Ilizarov external hinged frame fixation was implemented. This dual technique can be considered as a rational approach for such an extreme deformity as it stabilizes, progressively corrects, and prevents recurrence...

CASE: A 29-year-old healthy woman, 19 weeks pregnant, sustained a right posterolateral knee dislocation with multiligamentous injury and a complete occlusive injury to the right popliteal artery yet had adequate distal perfusion. She declined operative management for both the knee dislocation and the arterial injury, and successful collaboration between obstetrical, vascular, and orthopaedic surgical services resulted in limb preservation and restoration of function. CONCLUSION: This is a unique case of traumatic complete popliteal artery occlusion with adequate collateral arterial perfusion after a reducible posterolateral knee dislocation in a pregnant patient that resulted in limb preservation with nonoperative management...
