Abstract:
Abstract More than 20 million Americans have osteoarthritis (OA), which affects the knee more often than any other joint and is the most common cause of long-term disability in persons older than 65 years. Knee OA is common, particularly in older patients and especially the obese. Knee injury, depending on the severity and type, can increase the risk of developing and the rate of progression of OA. In assessing impairment for knee OA, the evaluator must obtain a thorough history and physical examination and identify all potential risk factors. To opine that an injury caused OA, the evaluator s

Introduction: Osteoarthritis (OA) is the most common form of inflammatory joint disease. It occurs most frequently in the knees, hips, the spine (vertebrae), and ankles. Radiological prevalence of knee OA in Indonesia reaches 15.5% in men and 12.7% in women aged between 40-60 years. X-ray imaging is routinely used in clinical practice to confirm knee OA diagnosis and in clinical research to monitor the progression of knee OA.

Osteoarthritis (OA) is the most common form of arthritis and can often occur in the knee. While convolutional neural networks (CNNs) have been widely used to study medical images, the application of a 3-dimensional (3D) CNN in knee OA diagnosis is limited. This study utilizes a 3D CNN model to analyze sequences of knee magnetic resonance (MR) images to perform knee OA classification. An advantage of using 3D CNNs is the ability to analyze the whole sequence of 3D MR images as a single unit as opposed to a traditional 2D CNN, which examines one image at a time.

Numerous musculoskeletal pathologies have been linked to altered tissue loading conditions. However, it is extremely difficult to measure in-vivo tissue loads, and internal loads are often inferred from external variables. A typical example is knee osteoarthritis (OA), with one of the main causes believed to be inappropriate loading in the tibiofemoral joint during walking. Large external adduction moments have been associated with the progression of knee OA, increased pain, and worse outcome after osteotomy surgery.

Abstract:
Osteoarthritis (OA) is a disorder of synovial joints and is characterized by the combination of focal hyaline cartilage loss and accompanying subchondral bone remodelling and marginal new bone formation (osteophyte). It has genetic, constitutional, and environmental risk factors and presents a spectrum of clinical phenotypes and outcomes. OA commonly affects just one region (e.g. knee OA, hip OA). However, multiple hand interphalangeal joint OA, usually accompanied by posterolateral firm swellings (nodes), is a marker for a tendency towards polyarticular ‘generalized nodal OA’.

ABSTRACT Background: Osteoarthritis (OA) of knee joint is a degenerative disease that results in decreased function and pain. Orthotic devices can reduce knee adduction moment, pain, and improve function in knee OA. The purpose of this study was to examine knee orthosis uptake in reducing pain in patients with knee osteoarthritis. Subjects and Method: A meta-analysis and systematic review was conducted by search published articles from PubMed, Science Direct, Google Sscholar, Mendeley, and Clinical key databases.

Abstract:
It is well known that the disease of osteoarthritis (OA) deteriorates the lubrication properties of articular cartilage. Previous studies [1,2] have demonstrated that the coefficient of friction of rabbit knee cartilage increases significantly in OA models. The coefficient of start-up (static) friction in the normal canine knee joint has also been observed to increase with the duration of static loading [3], and further increases in the start-up friction of osteoarthritic cartilage were induced by surface abrasion and papain injection [4]. However, the change in the start-up friction due to OA

Abnormal loading of the medial compartment of the knee is believed to be a contributing factor to the development of medial compartment knee osteoarthritis (OA) [1]. Treatment strategies for patients with medial knee OA include both invasive (i.e., surgery) and non-invasive (e.g., gait modification) options. A variety of modified gait patterns have been proposed as non-invasive treatments for patients with medial knee OA.

Abstract:
Meniscal tears are one of the most common knee injuries with an incidence rate of 60–70 per 100,000 person-years [1]. Although arthroscopic partial meniscectomy, the leading treatment for meniscal tears, decreases pain, the risk of knee osteoarthritis (OA) is four times higher for a meniscectomized knee compared to an uninjured knee [2]. Prior research has shown that meniscectomized knees have reduced sagittal-plane range of motion in the early period following surgery (6 to 18 months) [3–5]. These observations suggest a mechanical pathway to knee OA, in which alteration in ambulatory knee fun

Abstract:
The anterior cruciate ligament reconstructed (ACL-R) knees suffer from a higher risk for osteoarthritis (OA) which is the major leading cause of disability[1]. In order to understand the mechanism of knee injury and the development of OA, precise 3-D knee joint motion is often determined by invasive, or radioactive approaches[2]. For studying daily activities like walking which has larger range of motion (ROM), the skin marker-based technique remains the only feasible way[3].

Abstract:
Background: Osteoarthritis (OA) is a degenerative disease that mainly affects articular cartilage of joints. OA most commonly affects the knees and causes pain and reduces quality of life in older adults. Blood flow restriction (BFR) occludes arterial and venous flow during exercise using a blood pressure cuff placed on the proximal lower limb. This creates an intramuscular hypoxic environment which promotes muscle hypertrophy. High load training can cause pain and inflammation in knee OA patients due to increased stress. BFR can allow patients with knee OA to use lower loads to achieve benefi

Abstract:
Abstract Knee osteoarthritis (OA) is the most frequent form of lower limb arthritis. The severity of knee OA patients is graded, with moderate patients having deteriorating symptoms due to abnormal lower extremity alignment and poor lower leg rotation. To prevent the worsening of symptoms, orthoses are prescribed for patients with knee OA. Although conventional orthoses can either correct alignment or guide the rotation of the lower leg, it is difficult for them to achieve both corrective force and normal range of rotation. Therefore, an orthosis equipped with a mechanism that can simultaneous

The main research question is what are different costing methodologies used and its quality in studies related to cost effectiveness of TKR compared to non-surgical treatment procedures. Based on this review question, the following objectives are proposed: 1. To assess different methodologies, scope and quality of studies related to cost effectiveness of TKR compared to non-surgical management. 2. To synthesize evidence of TKR cost and compare the variations across different countries. In
