Femoral Extramedullary Versus Intramedullary Alignment Systems in Total Knee Arthroplasty
Knee OsteoarthritisA prospective study will be performed to compare the clinical outcome after total knee arthroplasty (TKA) using two different alignment systems: an extramedullary system versus an intramedullary system. The extramedullary femoral alignment system is newly designed. These two systems are used to make the distal femoral resection in 100 patients in a random order.
Improvement of Implant Survival in Total Joint Arthroplasty of the Trapeziometacarpal Joint
OsteoarthritisThe study evaluates implant survival in total joint arthroplasty of the Trapeziometacarpal (TMC) joint by monitoring the survival of different implant types using radiostereometry (RSA) evaluation of the implants.
Comparison of Hip Resurfacing to Large Femoral Head Total Hip Arthroplasty
OsteoarthritisAvascular NecrosisThis study evaluates femoral head resurfacing versus a large femoral head (Durom®) total hip system. This is a prospective randomized trial.
Prevention of Post-Traumatic Osteoarthritis (OA)
OsteoarthritisJoint injury and trauma dramatically increase the risk of developing osteoarthritis (OA). The purpose of this study is to determine what factors lead to decreased pain, improved joint function, and repair of the joint surface in post-traumatic OA. Study hypotheses: 1) Ankle motion during distraction will result in clinically significant improvements in Ankle Osteoarthritis Scale scores, SF-36 scores, and improved cartilage thickness distribution over the habitually most heavily loaded portion of the articular surface, as compared to the use of distraction without ankle motion. 2a) Ankles with low geometric surface irregularity and greater range of motion will have better preservation of neo-chondroid tissue (increased normalized cartilage thickness and reduced longitudinal compressive strain in the habitually heavily regions of the articular surface) than those with high surface irregularity. 2b) Low geometric surface irregularity and greater range of motion will have reduced habitual focal or regional contact stress elevation. 3) Joints that have better improvements in Ankle Osteoarthritis Scale scores and improved cartilage thickness distribution over habitually heavily loaded portion of the articular surface will have improved normalization of synovial fluid markers of biosynthetic/degradative activity and oxidative stress.
Radial Medical - GAPS
OsteoarthritisThis study will prospectively compare compliance rates between a novel FDA cleared wearable compression therapy with and without digital engagement for DVT prophylaxis in both hospital and home environments after total knee or hip arthroplasty.
The Effects of the Electro, Heat and Cold -Therapy During Physiotherapy Treatment in Osteoarthritis(OA)...
Knee PainOsteoarthritisThe objective of this clinical trial is to evaluate the pain relief and daily functioning improve, in patients suffering of Osteoarthritis of knee, with HOT/COLD/ Electro therapy during physiotherapy treatment
Leisure Expectations About Physical Activity Study
Hip OsteoarthritisKnee OsteoarthritisTo pilot test an activity-focused intervention that educates patients undergoing total hip (THA) or total knee (TKA) arthroplasty due to osteoarthritis about the appropriate type, frequency, intensity, and duration of expected leisure activities after surgery and to determine if the intervention changed expectations.
Platelet-Rich Plasma vs Corticosteroid Injection as Treatment for Degenerative Pathology of the...
Degenerative Joint Disease1.0 BACKGROUND AND HYPOTHESES 1.1 Osteoarthritis is a continuous and entirely physiologic adaptive process that occurs in every joint. These include the replication of cells that produce matrix, enzymes, protease inhibitors, cytokines, and other peptides. Along with the synthesis of new tissue there is a release of breakdown products into the synovial fluid. Enzymes and phagocytes are required to clear these breakdown products. Normal tissue turnover involves synthesis and breakdown in well-regulated balance. In the degenerative state this balance is upset producing inflammation-derived alterations to the synovium, cartilage, capsule, tendons, and bone. Common causes of such alterations include increased loading, physical stress, and traumatic injury to the joint. 1.2 The rationale for the use of corticosteroids in temporomandibular joint therapy is that they inhibit prostaglandin synthesis and decrease the activity of collagenase and other enzymes that degrade the articular cartilage. Platelet rich plasma is a novel therapeutic agent that has several potential advantages over corticosteroids for the treatment of degenerative pathology of the temporomandibular joint. Platelet rich plasma has been shown to have anti-inflammatory, analgesic, and anti-bacterial properties. It also restores intra-articular hyaluronic acid, increases glycosaminoglycan condrocyte synthesis, balances joint angiogenesis, and provides a scaffold for stem cell migration. Autologous platelet rich plasma injections for treatment of knee cartilage degenerative lesions and osteoarthritis have shown longer efficacy than hyaluronic acid injections in reducing pain and recovering articular function. Similarly, platelet rich plasma has shown to have better outcomes than corticosteroid injections in the management of lateral epicondylitis, and better outcomes than hyaluronic acid injections in the management of osteochondral lesions of the talus. 1.3 Current treatments for degeneration and osteoarthritis of the temporomandibular joint are focused primarily on palliation by reducing inflammation and inflammatory mediators. This study seeks to validate a therapeutic agent that has the potential to actively prevent the progression of degeneration in addition to reducing pain and inflammation
Elasticity of the Hoffa's Fat Pad in Patients With Knee Osteoarthritis
Knee OsteoarthritisElasticity Imaging TechniquesKnee osteoarthritis (OA) is a common problem in clinical settings. Knee OA is well known for its association with the wear and tear of the cartilage and osteophyte formation. Evidence has suggested the importance of the infrapatellar fat pad, known as Hoffa's fat pad, during the development of knee OA. Some studies have demonstrated the protective role of the infrapatellar fat pad, whereas others have suggested an inflammatory role such as increased fibrosis and proinflammatory cytokine levels. Ultrasound is exceptionally convenient in the assessment of the musculoskeletal system, and elastography is a tool to evaluate tissue texture. Therefore, in this study, we investigated the Hoffa's fat pad in knee OA patients by using elastography.
