In Vivo Kinematics for Subjects Implanted With Klassic Total Knee Arthroplasty (TKA)
Total Knee ArthroplastyOsteo Arthritis Knee2 moreIn vivo knee kinematics will be assessed for 20 subjects that have been implanted with a Total Joint Orthopedics Klassic knee system by Dr. Aaron Hofmann of the Hofmann Arthritis Institute's Center for Precision Joint Replacement. This is the location from which all participants will be recruited and where fluoroscopy data collection will occur. Participants will undergo fluoroscopic surveillance of their implanted knee using a C-arm fluoroscopic unit while performing a deep knee bend activity at least six months post-operatively.
Evaluation of the Brakes and Levers on the Use of an E-health Application for Osteoarthritis Patients...
OsteoarthritisKneeOsteoarthritis is the most common articular disease affecting the joint in a comprehensive and progressive manner. It is a chronic pathology correlated with age since nearly one in two adults is affected by osteoarthritis. The care of osteoarthritis is based on pharmacological and non-pharmacological treatment. The latest recommendations support the non-pharmacological part including regular physical activity, therapeutic education and weight loss. Today tools are lacking for the patient and the practitioner to ensure long-term motivation and support. Connected objects, as future-oriented tools, are a customizable way to meet the expectations of both patients and professionals. The main objective of this study is to analyze the expectations regarding the use of a smartphone application for monitoring and support in the practice of exercises and regular physical activity in patients osteoarthritic. The secondary objective is to collect information on the use of connected objects dedicated to the management of osteoarthritis by patients and health professionals.
Investigation of Thenar Muscles Morphometric Parameters in Patients With TMC OA
Thumb OsteoarthritisMuscle Atrophy or WeaknessIn this study, investigators aimed to investigate the morphometric parameters tenar muscles and joint configuration in patients with trapeziometacarpal osteoarthritis (TMC OA) osteoarthritis stages, thenar muscle parameters, radial subluxation rate, functional level and hand dexterity.
A Novel Smartphone Application for "Smart" Knee Osteoarthritis Trials
OsteoarthritisKneeThe overarching goal is to develop a mHealth App that can use smartphone embedded sensors to objectively collect physical function data in individuals with knee osteoarthritis (KOA) in the context of daily life.
Varus Stem Positioning of a Cementless Anatomical THA. (VARABG)
OsteoarthritisArthroplasty ComplicationsVarus positioning is the most common femoral malposition in total hip arthroplasty (THA). The aim of this study was to compare the long-term results of an anatomical cementless femoral stem positioned in varus with those in neutral alignment.
Ultrasound Imaging of Quadriceps Muscle in Patients With Knee Osteoarthritis
OsteoarthritisKneeEcho intensity (EI) assessment using ultrasonography helps monitoring disease-induced muscle quality changes. However, there are no study investigating the reliability of EI in patients with knee osteoarthritis (OA). The primary aim of the present study was to investigate the inter and intra-rater reliability of EI evaluation by grayscale histogram analysis of quadriceps femoris muscle in patients with knee OA. The second aim was to compare the mean grayscale values obtained using both the Free Hand Tool (FHT) and Rectangular Marquee Tool (RMT) methods in ImageJ. Thirty patients with knee OA were included in this cross-sectional study. The echogenicity measurements of the Rectus Femoris, Vastus Inter-medius, Vastus Lateralis and Vastus Medialis were performed by two different researchers. Reliability analysis of EI measurements were calculated with using intraclass correlation coefficient (ICC), standard error of measurement (SEM) and coefficient of variation (CV) and Bland and Altman plot analysis.
The Presence Of Sarcopenia In Patients With Knee Osteoarthritis
SarcopeniaOsteoarthritisOsteoarthritis (OA) is one of the most common joint disorders worldwide . The knee is the most common symptomatic joint in osteoarthritis. In this study, we evaluated the presence of sarcopenia multidimensionally in patients with knee osteoarthritis (OA) using clinical, ultrasonographic and biochemical parameters, and in this respect, it was aimed to investigate the relation between OA and sarcopenia and to identify the most practical, easily accessible and inexpensive method for investigating sarcopenia.
Effect of Total Knee Arthroplasty on Sarcopenia in Patients With Osteoarthritis in the Knee
SarcopeniaOsteoarthritis1 moreSarcopenia is a wasting disease with the locomotion system in the aged population. It is defined as the decline in muscle mass (lean body mass) and strength with the advance of age. The prevalence of sarcopenia increases with age, reaching an astounding 50% among the population aged over 75 in the United States. Sarcopenia is often associated with frailty, falls, and disability. Studies have found sarcopenia can be a predicting risk factor for fractures in the elderly. In addition, sarcopenia predicted a higher chance of mortality in nursing homes.
Radioscapholunate Fusions After Wrist Trauma
Posttraumatic Radiocarpal OsteoarthritisThe investigators conduced a clinical trial to evaluate the clinical and radiographic results after radioscapholunate fusion in case of posttraumatic radiocarpal osteoarthritis. Because of poor clinical result, many authors upgrade the procedure including excision of the distal pole of the scaphoid and later excision of the entire triquetrum. Only one study compared the three procedures in 17 patients. The investigators performed the same comparison in 85 patients with a mean follow up of 9,1 years (1-23)
The Inclination of the Proximal Tibiofibular Joint Surface and Medial Compartment Knee Osteoarthritis...
OsteoarthritisKneeThis study aims to research on the association between the inclination of the proximal tibiofibular joint surface and medial compartment knee osteoarthritis. The proximal tibiofibular joint radiographs of the participants will be taken. The angle of inclination of the proximal tibiofibular joint surface in two groups will be compared.
