Comparison of the in Vivo Stability of 2 Cementless TKA Designs
Knee OsteoarthritisThe goal of this randomized controlled trial is to analyze the stability of a cementless Total Knee Arthroplasty (TKA) over time and compare it to a well-documented implant in patients with knee osteoarthritis. The main aim is to answer if there is a difference in stability over time as a measure of long time survivorship in these 2 implants. 50 participants will be randomly allocated to receive either the Triathlon Tritanium (Stryker) or the Global Medacta Knee Sphere (GMK Sphere, Medacta) 3D printed cementless TKAs.
Conventional Instrumentation, Computer Navigation, and Robotic Assistance Techniques in TKA
Knee OsteoarthritisKnee osteoarthritis is a debilitating disease that can cause severe knee pain and significant limitations to patients' activities of daily living. Total knee arthroplasty (TKA), also known as knee replacement surgery, is a well-established and successful procedure for treatment of end-stage knee osteoarthritis. Over the years, TKA surgical techniques and implant technology have improved, resulting in better patient outcomes and implant survivorship. Despite continuous improvements being made to this high demand procedure, malalignment of component position is a well-known cause of post-operative complications, including knee pain, component loosening, and failure requiring revision surgery. Advanced techniques that utilize computer navigation or robotic-arm assistance have been developed in an attempt to avoid malalignment. Both technologies were created with the goal of improving the precision of implant positioning and implant sizing in order to improve lower limb alignment and joint line alignment. The OrthoAlign KneeAlign computer assisted navigation system is a commercially available device that uses gyroscopic limb position sensing technology mounted to intramedullary and extramedullary jigs to measure bone resection cuts in TKA that ultimately dictate implant position. The Zimmer Biomet ROSA Knee System is a commercially available, FDA-approved robotic assistant for performing TKA. It uses pre-operative x-rays to create a three-dimensional image of the patient's knee anatomy, which is used to create a pre-operative template of the implants to be used and provides intra-operative guidance for bone cuts during the TKA. The robotic system also assesses the soft tissue envelope around the knee and can assist with the soft tissue balancing of the knee arthroplasty. Alternatively, it can also be used in an imageless mode where bone cuts are performed based on intra-operative mapping using anatomic landmarks. To date, there have been no prospective studies comparing the implant positioning and patient outcomes directly of the KneeAlign system with the ROSA system and conventional TKA instrumentation techniques.
Effects of Vagus Nerve Stimulation on Central Pain Sensitivity & Parasympathetic Function in Knee...
Knee OsteoarthritisCentral Pain SyndromeThe goal of this clinical trial is to test the feasibility and effectiveness of transcutaneous vagus nerve stimulation (tVNS) to the ear on pain and autonomic function in people with knee osteoarthritis (OA). The main questions it aims to answer are: 1) whether tVNS is feasible to be used in people with knee OA; 2) whether tVNS demonstrates the trend in improving knee pain; and 3) whether tVNS has physiological effects on autonomic function (e.g., parasympathetic function) and pain perception in the central nervous system such as brain (i.e., central pain mechanisms). Participants will be asked to complete a battery of self-reported questionnaires about their demographic and behavioral information, ethnicity, pain, sleep, psychological/emotional symptoms. Subsequently, participants will complete baseline assessment where investigators will assess their knee pain severity, central pain sensitivity, and heart rate variability (a measurement for autonomic function). Then participants will receive a 60-minute tVNS. Investigators will redo the same assessment as baseline assessment after tVNS intervention to see the degree of knee pain, central pain sensitivity, and autonomic function changes. At the end of the study, investigators will assess their satisfaction level with the tVNS intervention and the feasibility of the intervention (e.g., completion rate, side effects).
Clinical Evaluation of Reverse Versus Anatomic Shoulder Arthroplasty Techniques in the Treatment...
Shoulder OsteoarthritisOsteoarthritis (OA) is the most common form of arthritis, affecting millions of people worldwide and it is common in an aging population. Surgical shoulder replacement (arthroplasty) is typically considered when non-surgical measures, such as physiotherapy or medication, have failed. There are two commonly performed surgical replacement procedures in patients who have advanced shoulder OA, and are 65 years of age and older: "Total Shoulder replacement or Arthroplasty (TSA)" and "Reverse Total Shoulder Arthroplasty (RTSA)". Few studies have compared the two procedures. Surgeons face uncertainty regarding which procedure to perform in patients 65 years of age and older. This pilot Randomized Controlled Trial (RCT) will compare the "TSA" and "RTSA" procedures, in patients 65 years of age and older. Participants will be assigned at random, (like flipping a coin), to one of the two groups (TSA or RTSA). The overall goal of this pilot study is to determine which procedure produces better functional and quality of life outcomes with fewer complications within the first 12-months after surgery. Moreover, pilot data will help determining the feasibility of conducting a larger trial comparing TSA versus RTSA surgical management in 65 years of age and older participants with advanced shoulder OA.

Knee OsteoarthritisLLLT is in use to treat different musculoskeletal condition. Osteoarthritis is one of the conditions needing LLLT for therapeutic effects. LLLT has been used in different previous studies using different points on joint and also on acupuncture points. This study is going to compare the effectiveness of LLLT on both points. Omega xp device is going to be used in this study.
Comparing Different Types of Physical Therapy for Treating People With a Meniscal Tear and Osteoarthritis...
Meniscal DegenerationOsteoarthritis1 moreKnee osteoarthritis is a disabling problem affecting over 15 million adults in the United States. Many people who have knee arthritis also experience painful meniscal tears. There are a number of different treatments that can be used to manage meniscal tears in the presence of knee arthritis. Treatments include surgically removing the damaged part of the meniscus; strengthening exercises to improve pain and function; manual therapy including massage and mobilization; acupuncture; and others. The combination of surgery and exercise therapy was long thought to be the best treatment. However, recent studies have shown that surgery followed by physical therapy is no more effective than physical therapy by itself. While physical therapy alone has been shown to result in similar pain relief as arthroscopic surgery, researchers have not yet done studies to determine what type of physical therapy is best for people with knee arthritis and meniscal tears. In the "TeMPO" Trial, we will be comparing 4 different, non-operative physical therapy regimens in order to gain a better understanding of how physical therapy works and what regimen will best reduce pain and improve function in persons with meniscal tear and osteoarthritis. The four arms in this randomized trial will contain different combinations of therapeutic treatments including in-clinic therapist-supervised exercise, in-clinic topical therapies, and exercises to be completed at home. Subjects in three of the arms will also receive motivational SMS (text) messages intended to improve adherence to the home exercise regimen. TeMPO is designed as a randomized controlled trial. Participants will be assigned randomly to one of the four arms. All arms include therapies that have been previously shown to work in clinical settings. One arm also contains some placebo treatments. The placebo treatments will help us to understand what aspects of physical therapy actually make people feel better. Our hypothesis is that subjects in the arm that includes in-clinic physical therapy and a home exercise regimen will experience more pain relief than subjects in each of the other arms. Also, we expect that subjects in the arm that receives the home exercise regimen and SMS messages will experience more pain relief than subjects in the arm that receives home exercise without the SMS messages.
