The Angle of the Metacarpophalangeal Joint of the Thumb During Maximal Pinch Strength
Post-traumatic; ArthrosisOsteoarthritis ThumbThe aim of the study is to measure the position of the metacarpophalangeal joint of the thumb during key-pinch, tripod-pinch and opposition-pinch in normal volunteers, to determine the optimal position of metacarpophalangeal joint arthrodesis.

Mind-body Therapy (Remotely Delivered) for Knee Osteoarthritis
Knee OsteoarthritisThis proposal aims to provide crucial knowledge about the neurobiological mechanisms underlying Tai Chi mind-body therapy for knee osteoarthritis (OA). The central mechanism of knee OA pain will be investigated using brain imaging technology to evaluate how brain function and structure change in response to mind-body exercise over time. Sixty eligible individuals who meet the American College of Rheumatology criteria for knee OA will be randomized into Tai Chi or wellness education interventions for 12 weeks. The investigators will compare changes in resting state functional connectivity of the cognitive control network, and functional magnetic resonance imaging responses to pressure pain and brain morphometry, as well as their association with clinical outcomes. The findings will lead to the establishment of a new treatment paradigm in OA and have broad application to the management of chronic musculoskeletal pain.

Study of Cingal® for Symptomatic Relief of Osteoarthritis of Ankle Joint
OsteoarthritisAnkleThis Trial will obtain clinical data to support an expanded indication for a single injection of Cingal® used for the symptomatic relief of osteoarthritis in the ankle joint.

The Effect of Exercises of Different Intensity Applied After Total Knee Arthroplasty on Exercise-Induced...
Knee OsteoarthritisPain1 moreThe aim of this study was to investigate whether exercise-induced hypoalgesia (EIH) is present following exercise in patient after total knee arthroplasty (TKA) and if so, if it changes with exercise intensity. A repeated measures and single-blinded randomized study were done. Thirty-eight patients 24 hours after TKA were randomly assigned to either low intensity exercises (LIE) group or high intensity exercises (HIE) group. An exercise programs lasted for five days during the hospitalization period. Pain severity was assessed by Visual Analog Scale (VAS) (0-10 mm). Pressure pain thresholds (PPTs) were measured over quadriceps and biceps brachii and muscles immediately before and after exercise.

Pain Control After Total Knee Arthroplasty
Knee OsteoarthritisPatients are randomized to receive pain control after Total Knee Arthroplasty with either a regional pain catheter or a local intraarticular pain catheter. Pain, analgetic use and mobility is asessed.

A Pilot Trial of Acupuncture for Knee Osteoarthritis With Differential Functional Status of Acupoints...
AcupunctureKnee Osteoarthritis1 moreThe investigators plan to undertake a rigorous multicentre randomised controlled trial, comparing acupuncture on sensitized acupoints with low/non-sensitive points or no acupuncture (waiting-list), to test if acupuncture on sensitized acupoints may result in improved treatment outcomes in patients with Knee osteoarthritis (KOA).The current pilot study aimed to assess the feasibility of performing the definitive randomised controlled trial.

iAssist vs. Conventional Instrumentation in Total Knee Arthroplasty
Avascular NecrosisPost-traumatic; Arthrosis1 moreThe purpose of this prospective study is to evaluate Zimmer® iASSIST™ with respect to radiographic, clinical and economic outcomes and compared to conventional instrumentation in primary total knee arthroplasty (NexGen or Persona knee implants).

Evaluation of Biomarkers in Human Synovial Fluid
OsteoarthritisOsteoarthritis is a condition that causes joints in the human body to deteriorate over time. This condition affects more than 250 million people around the globe. Currently, the goal of treating osteoarthritis involves reducing the severity and pain that results from the disease. The ultimate goal of this study is to identify patients with pre-arthritic joints (before symptoms or disease characteristics appear) in an effort to find and use treatments that stop or slow the disease. Joints are filled with a naturally occurring liquid known as synovial fluid. Molecules (biomarkers) and genetic expression of various cell types within synovial joint fluid may serve as measures of onset and progression of osteoarthritis. These samples have the potential to improve diagnosis, classification, and treatment, possibly changing the natural history of this debilitating disease. The purpose of this study is to develop a collection of synovial fluid samples from the shoulder, hip and knee for the analysis of biomarkers and cellular and genetic components therein to better understand the pre-arthritic joint, progression to disease, and response to interventions.

Does Intraoperative Intravenous Iron Enhance Postoperative Oxygenation Profile in Total Knee Arthroplasty...
OsteoarthritisThe objective of the present study is to determine the impact of intraoperative IV-iron supplementation on postoperative oxygenation profile by comparing the postoperative PaO2/FiO2 ratio with or without IV-iron supplementation in old patients undergoing elective uni-limb total knee arthroplasty surgery.

Comparison of Nonposterior- and Posterior-Stabilized Mobile-Bearing Total Knee Arthroplasty
OsteoarthritisThe purpose of this study is to determine if there are any clinical or radiographic differences in non-posterior stabilized rotating mobile bearing design versus a posterior stabilized rotating mobile bearing designs.
