The purpose of this study is to compare three prosthesis designs to compare three prosthesis designs for total knee arthroplasty and determine the best option for patients in need of a knee replacement.
Knee 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.
The goal of this study is to analyze patient:provider communication surrounding the discussion of difficult clinical conversations such as knee replacement options. This study will also examine how using the teach-back communication technique can improve communication between patients and providers. Orthopedic residents, fellows, physician assistants, and attendings that agree to participate will be consented. Patients, who are likely to engage in a difficult clinical conversation, such as those who have a clinical indication for a Total Knee Replacement or a Partial Knee Replacement, will be recruited from participating providers clinical schedules. Patient:provider interactions will be recorded and then the providers will attend a 1 hour education lecture about how to use teach-back. After attending the lecture, additional patient:provider interactions will be recorded and analyzed via a qualitative approach. Additionally, providers will participate in a semi-structured interview to capture their perceptions of teach-back and what challenges and benefits they may derive from using it.
The primary objectives of this study are to apply best-practice stated-preference methods to quantify patient preferences for benefit-risk tradeoffs associated with arthroplasty treatment options for end-stage osteoarthritis of the knee. Duke will develop and administer stated-preference surveys to adult patients (Ages 40-80) with knee pain to collect preference data, estimate the relative importance of treatment features and outcomes, and estimate maximum acceptable risks for given benefits and minimum acceptable benefits for given harms. This study proposal describes plans for the patient stated-preference survey.
The purpose of this study is to examine the impact of an OA-specific aerobic and strengthening exercise program, delivered within the workplace, on mobility, pain, physical capacity, and resilience among workers with knee or hip OA as well as those with no joint pain. The investigators hypothesize that exercise designed for OA, delivered at work, will improve all of these outcomes.
Knee osteoarthritis is a common disease that causes joint pain, stiffness, and movement limitation. Nearly 50% in those 75 years and above are affected. In Taiwan, the reported prevalence was more than 6000 per year. The cause of pain is joint instability and structure changed, including hyaline articular cartilage lost, bony remodeling, capsular stretching and periartcular muscle weakness. Current guidelines for treatment of symptomatic knee osteoarthritis include exercise, anti-inflammatory drugs, transcutaneous electrical stimulation(TENS) and magnetic fields(MF) which reduce pain and improve the patient's quality of life. However, conservative therapies and oral supplements have been evaluated but are without clear efficacy. Prolotherapy is an injection therapy for chronic musculoskeletal pain. One of the hypotheses is stimulating local healing and current study demonstrated clinical benefit for pain and improvement of function. The effects of multi-point injections were more pronounced in several studies than single-point injection. Extracorporeal shock wave is common treatment for kidney stones, has been widely used in soft tissue diseases, such as calcified tendon lesions and plantar fasciitis. The theory of extracorporeal shock wave is energy of high-frequency vibration caused destruction of stones and other hard material and by increasing the rate of vascular regeneration in the injured area and increasing the rate of autologous tissue repair, possible biological processes include increased mesenchymal stem cell proliferation and differentiation, slowing the inflammatory response and antimicrobial efficacy. Current studies have shown equivalent clinical outcomes on calcific rotator cuff tendinopathy among extracorporeal shock wave therapy, sono-guided acupuncture and arthroscopic surgery and the extracorporeal shock wave has the advantage of non-invasive treatment. Taking the advantages of non-invasive treatment of extracorporeal shockwave. We want to design a randomized control trial by multi-point shockwave therapy and physical therapy compared with placebo shockwave therapy and physical therapy. Two randomized controlled trial (RCT) reported improvement in outcomes in response to shockwave therapy but were not methodologically rigorous. The investigators therefore conducted a two-arm RCT to assess the hypothesis that adults with symptomatic knee pain receiving shockwave therapy will report greater improvement in knee-related quality-of-life than sham shockwave therapy.
The primary objective of this study is to obtain long-term implant survivorship (out to 10 years) and to assess clinical, patient-reported outcome measures, and radiographic data for the commercially available Physica system. For ancillary arm, from baseline to 5-year follow-up.
Metal ion release from metal implants may have side effects. It can be reduced by coating of the implant. This study compares coated and uncoated TKA.
The study was designed to test patient acceptance and system usability and to assess clinical outcomes of a home-based rehabilitation program using a novel kinematic biofeedback system in the rehabilitation after total knee replacement versus conventional rehabilitation, This system allows the patients to perform independent rehabilitation sessions at home, under remote monitoring from the clinical team. The investigators hypothesize that the system will be well received by patients and that the clinical outcomes will be at least similar those of conventional rehabilitation. This is a quasi-randomized controlled trial with active comparator. Patients will be enrolled pre-operatively and divided into 2 groups: experimental group and conventional rehabilitation group according to geographical criteria. Both groups will perform 8 weeks of rehabilitation starting between day 7 and 10 after surgery. The experimental group will perform daily rehabilitation sessions at home using the system, under remote monitoring from a physical therapist. The conventional rehabilitation group will perform 1h rehabilitation sessions 3 times a week, at home, given by a physical therapist. The following feasibility outcomes will be registered: enrollment rate, retention rate (drop-outs), compliance to the program, independence of use, need for therapist contact and patient satisfaction. Clinical outcomes will be measured at weeks 4 and 8 and then at 3 and 6 months. The primary outcome will be measured in terms of patient performance in the Timed-up-and-Go (TUG) test in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: b) Knee Osteoarthritis Outcome Score); c) range of motion of the knee joint.
