gonarthrosis

BACKGROUND AND OBJECTIVES: Advanced osteoarthritis of the knee joint severely affects the patient's mobility, compounded by pre-existing comorbidities such as metabolic preconditioning (such as obesity, dyslipidemia, hyperuricemia, and insulin resistance syndrome) and both type I and type II diabetes. The success of total knee arthroplasty is influenced by knowledge and management of risk factors. The present study aims to evaluate differences in the evolution of risk factors such as obesity, injuries, and sedentary lifestyle, distinguishing those with metabolic preconditions and diabetes...

INTRODUCTION: Achieving stability in total knee arthroplasty (TKA) is crucial for long-term implant survival. In cases of severe deformity or ligament laxity, constrained implants may be required. Traditionally, increasing constraint involved intramedullary stems. However, there are intermediary alternatives, including employing a constrained polyethylene insert without stems, thereby avoiding complications related to them. The study aims to evaluate our experience with a non-modular constrained (NMC) implant in primary TKA...

Persistent knee pain in patients around the fifth decade of life is a frequent cause of attention in rehabilitation consultations. The most common cause of diagnosis is knee osteoarthritis, considering the existence of different degrees seen in simple radiographies. The advanced degrees present joint space reduction, osteophytosis and subchondral sclerosis; however, in the initial degrees, the findings are more subtle and sometimes nonexistent for conventional radiology. Clinical ultrasound has partly come to fill this «diagnostic gap», making it possible to detect meniscal extrusions and small osteophytes as signs of incipient osteoarthritis and to relate them as triggers of pain...

INTRODUCTION: The aim of this study was to compare the results of cementless bilateral total knee arthroplasty (TKA) between individuals in different obesity groups. MATERIALS AND METHODS: This was a retrospective cohort study. Patients with a body mass index (BMI) greater than 25 who underwent bilateral TKA for gonarthrosis between 2014 and 2020 and completed a minimum follow-up of 24 months were included. Age, sex, height, weight, BMI, operation time, length of stay, patient satisfaction, knee scores and complications were compared...

INTRODUCTION: Gonarthrosis is arthrosis of the knee joint, a chronic non-inflammatory disease manifested by progressive destruction of the intra-articular cartilage, accompanied by abnormal formation of the bones form the joint, changes in the synovial membrane and synovial fluid. Gonarthrosis is the most common type of arthrosis. Gonarthrosis can be treated conservatively and operatively. Among well-established surgical options for the treatment of medial gonarthrosis are high tibial osteotomy (HTO), unicompart-mental knee arthroplasty (UKA), and total knee arthroplasty (TKA)...

The primary objective of this study is to record the clinical outcomes of autologous conditioned plasma (ACP) for the treatment of knee osteoarthritis (OA) based on published literature. Multiple databases (PubMed, Embase, Web of Science and Scopus) were searched using terms for "knee OA" and the intervention "ACP" for articles published in English to January 4, 2024. All clinical studies using ACP for knee OA were included. Studies not utilizing ACP alone, i.e. used as an adjunct with other modalities or not focusing on the management of knee OA, were excluded...

OBJECTIVE: a hierarchical cluster analysis for the cardboard manufacturing industry was developed with the aim of identifying similarities between workstations in terms of musculoskeletal stress factors and their impact on workers' bodies. METHODS: The hierarchical clustering analysis was conducted using data from 44 workstations, which included six body part divisions and 51 stress factors as variables with 36 answer options. Firstly, the content of the dataset was defined...

Sodium hyaluronate (SH) is a high molecular-weight polysaccharide composed of repeating polymeric disaccharides of D-glucuronic acid and N-acetyl-D-glucosamine. SH is present in every connective tissue and organ, with synovial fluid having the highest concentration of SH in the body. The effectiveness of oral SH on gonarthrosis is known; although, its influence on the knees of healthy individuals is not. However, as severe diseases may require surgery, it is better to take care of healthy knees before the onset of gonarthrosis...

(1) Background: This study investigated the relationship between weather conditions, diurnal patterns, and total knee range of motion (ROM), as well as the severity of symptoms (pain and stiffness) in older adults with knee osteoarthritis. (2) Methods: An exploratory longitudinal study was conducted on 28 older adults with knee osteoarthritis (mean age 71.86 ± 4.49 years; 46.4% men, 53.6% women). We used as assessment tools the Visual Analog Scales (VAS) for self-reported local knee pain and stiffness, and goniometry for ROM...

OBJECTIVES: The study aimed to compare the outcomes of single-dose cross-linked hyaluronic acid and the linear regimen of three doses of HA knee injections among patients with gonarthrosis. PATIENTS AND METHODS: This single-center, retrospective study was conducted with 60 patients (47 females, 13 males; mean age: 57.9±4.29 years; range, 50 to 65 years) with Kellgren-Lawrence Grade 2 or 3 gonarthrosis between February 2020 and February 2022. Patients were either subjected to intra-articular cross-linked hyaluronic acid (n=30) or linear hyaluronic acid (n=30) injection treatments...

Kellgren-Lawrence (KL) grading appears to have become the de facto standard for reporting radiographic degeneration of knees, yet the much later-introduced and knee-specific International Knee Documentation Committee (IKDC) system has repeatedly been shown to have higher reliability. Although IKDC radiographic grading does have limitations - especially in cases of severe gonarthrosis - it appears to be the most reliable current system suitable for the purposes of arthroscopic knee surgeons, and was designed to encompass all three knee compartments...

Bisphosphonates are widely used in the treatment of osteoporosis but predispose the patient to the appearance of atypical fractures. The femoral subtrochanteric region is usually affected, but other bones can be as well. Atypical tibia fractures in patients with severe gonarthrosis is a therapeutic challenge. The present work reports the case of an elderly patient with advanced gonarthrosis who presented atypical tibial fracture. The patient made prolonged use of bisphosphonates for osteoporosis, presenting with pain and functional limitation resulting from gonarthrosis, which progressed to sudden pain in the right tibial metaphysis, preventing ambulation...

OBJECTIVE: The aim of the study was to assess lameness in dogs with advanced osteoarthritis of the hip and knee joints after a single autologous point-of-care transplantation of the Stromal Vascular Fraction (SVF) into the affected joint. MATERIALS AND METHODS: During a minilaparotomy, 10 g of falciform fat was removed from each patient for each joint to be treated. A modern and time-saving procedure (ARC TM System, InGeneron GmbH, Houston, USA) was used for the in-house preparation of the SVF, so that the isolated cells could be applied to the respective joint within 2 h after fat removal...

BACKGROUND: The spread of artificial intelligence (AI) has led to transformative advancements in diverse sectors, including healthcare. Specifically, generative writing systems have shown potential in various applications, but their effectiveness in clinical settings has been barely investigated. In this context, we evaluated the proficiency of ChatGPT-4 in diagnosing gonarthrosis and coxarthrosis and recommending appropriate treatments compared with orthopaedic specialists. METHODS: A retrospective review was conducted using anonymized medical records of 100 patients previously diagnosed with either knee or hip arthrosis...

BACKGROUND: Prolotherapy may be a good option in the complementary treatment of knee osteoarthritis (OA) patients, specifically for the increase of functionality. OBJECTIVE: To determine the effectiveness of prolotherapy in OA grade II - III in the functionality and muscular work of knee flexors and extensors. MATERIAL AND METHODS: a double-blind randomized controlled clinical trial was conducted. It included patients diagnosed with OA grades II-III...

OBJECTIVES: The standard surgical method for primary gonarthrosis in advanced stages is total knee arthroplasty (TKA), despite the risk of bleeding that requires transfusion. Blood transfusions are potentially dangerous. The aim of this study was to determine whether there is a statistical difference in the amount of bleeding and the need for transfusion between patients who received and did not receive perioperative local tranexamic acid in TKA. METHODS: The hospital data system was used to access the data of patients who underwent TKA in our clinic between January 2015 and January 2022 with a diagnosis of gonarthrosis...

This retrospective case-control study examined the relationship between the serum and synovial levels of cathepsin G (CatG) and cathepsin K (CatK) in patients with psoriatic arthritis (PsA) and their association with disease activity. Methods: This case-control study involved 156 PsA patients, 50 patients with gonarthrosis (GoA), and 30 healthy controls. The target parameters were measured using enzyme-linked immunosorbent assay (ELISA) kits. The serum levels of CatG and CatK were found to be significantly higher in PsA patients compared to both control groups ( p < 0...

BACKGROUND: Due to the presence of numerous problems in osteoarthritis, e.g., the presence of one or more chronic diseases, reduced self-esteem and reduced ability to cope, patients must undertake readaptation activities. In such circumstances, resources that are necessary for optimal adaptation become of particular importance. This cross-sectional study aimed to assess the impact of behavioral resources, namely self-efficacy and optimism, on quality of life perception in early-old-age patients with knee osteoarthritis...

We aimed to investigate the effects of delivering 3 gait retraining interventions (toe-in, toe-out, and placebo gait) on proxy measures of medial knee load (early- and late-stance peak knee adduction moment [KAM], KAM impulse, and varus thrust) in people with knee osteoarthritis, using a hybrid model of face-to-face and telehealth-delivered sessions over 5 months. This was an originally planned 3-arm randomized placebo-controlled clinical trial. However, during the 2021 COVID-19 outbreak and lockdown in Sydney, Australia, the study became a pilot randomized controlled trial with the remainder of interventions delivered via telehealth...

INTRODUCTION: population aging is a worldwide demographic phenomenon of the last thirty years. This increase in life expectancy leads to an increase in the incidence of degenerative diseases, mainly gonarthrosis. According to World Health Organization (WHO) estimates, 10% of the population over 60 years of age suffers from osteoarthrosis, and 40% of the population over 70 years of age suffers from gonarthrosis, figures that could increase in the next decade. Approximately 80% of people over 65 years of age present radiographic changes with evidence of gonarthrosis, being 10-25% of the reason for medical visits at the first level of care...
