Bicruciate-retaining (2C) Total Knee Arthroplasty (TKA) Versus Posterior-stabilized (PS) Total Knee...
Total Knee ArthroplastyKnee OsteoarthritisTotal knee arthroplasty (TKA) with the sacrifice of the anterior cruciate ligament is the standard treatment for severe knee osteoarthritis. A number of studies on the kinematics of the prosthetic knee tend to show that implants that preserve the cruciate ligaments best reproduce the kinematics of the healthy knee. The goal is to compare the clinical and radiological results in patients undergoing total knee replacement surgery according to the type of prosthesis used. It is anticipated that the bicruciate-retaining prosthesis will result in better function of the operated knee than the posterior-stabilized prosthesis. Method: Randomized controlled trial Monocentric Randomization will be done using sealed envelopes
Chitosan Versus Glucosamine Phonophoresis in the Management of Knee Osteoarthritis
Knee OsteoarthritisKnee ArthritisThe study will be conducted to answer the following questions: Is there an effect of phonophoresis using glucosamine on pain level , function and range of motion in knee osteoarthritis patients ? Is there an effect of phonophoresis using chitosan on pain level , function and range of motion in knee osteoarthritis patients ? Is there a difference between the effect of phonophoresis using glucosamine and phonophoresis using chitosan on pain level , function and range of motion in knee osteoarthritis patients ?
CT-based 3D Planning, Computer Navigation and Subsequent Migration Analysis in Total Hip Arthroplasty...
Hip OsteoarthritisThe aim of this study is to evaluate a new technique that optimizes the prosthesis position for patients who undergo total hip arthroplasty surgery. Today, most surgeons take a regular X-ray (2D) to plan the surgery. In this study, patients will do a computed tomography (CT) before surgery, and with the use of the new system, the investigators will be able to make a more accurate plan when it comes to prosthetic placement and leg length adjustment in 3D. The software uses artificial intelligence (AI) to generate the information required for clinical conclusions automatically, and it enables surgeons to adapt to each unique case and anticipate situations during surgery. The system also helps the surgeon during operation with a navigation tool to place the implant in the pre-operatively planned position. It guides surgeons in real-time to place the implants accurately. To see whether the plan and navigation were correct, the investigators will do a new computed tomography after surgery to look at the achieved result. In addition to planning and navigation, the same system can be used to measure the migration of the prosthesis in relation to the bone over time using AI by comparing multiple scans. The investigators aim to follow all patients for 2 years (total of 4 CT scans after surgery) with the intention to be able to foresee implant loosening.
Acupuncture vs Sham Acupuncture for Hand Osteoarthritis
Hand OsteoarthritisThe investigators plan to conduct this multicentered, sham-controlled randomized clinical trial to evaluate the efficacy and safety of acupuncture for clinical symptomatic improvement of hand OA.
The Effect of Implant Coating (BoneMaster) on Migration and Clinical Outcome in Hip Arthroplasty...
OsteoarthritisThis study focuses on the effect of the hydroxyapatite coating with BoneMaster on the fixation of the hip prosthesis in primary hip alloplasty. A hemispheric joint cup of the type Exceed cup (Biomet) characterized by a porous surface of titanium plasma spray is used. The surface is coated with hydroxyapatite deposited electrochemically (BoneMaster) and will be compared with an identical cup without hydroxyapatite.
Persona Total Knee Arthroplasty Outcomes Study
Knee Pain ChronicOsteoarthritis6 moreThe primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Persona fixed bearing knee implants used in total knee arthroplasty. The assessment will include implant survivorship and clinical performance.
A Randomized Trial Comparing High Tibial Osteotomy Plus Non-Surgical Treatment and Non-Surgical...
Knee OsteoarthritisThe purpose of this study is to compare patients with knee osteoarthritis (OA) receiving optimized non-surgical treatment plus surgical realignment of the tibia, or optimized non-surgical treatment only. We hypothesize that outcomes assessed at 12 and 24 months follow-up will suggest favourable changes in patients undergoing surgical realignment when compared to patients receiving non-surgical treatment only.
Efficacy of Exercise on Quality of Life and Physical Function in Patients With Knee Osteoarthritis...
OsteoarthritisPainThe overall contribution of this study is to increase the knowledge of the efficacy of strength and aerobic exercise on knee related quality of life, knee pain, and physical function in patients with knee osteoarthritis (OA). Knee OA is one of the most important diseases within musculoskeletal conditions affecting a considerable number of people worldwide. This randomized controlled trial will involve one intervention group delivered strength exercises and one group delivered aerobic exercise (ergometer cycling). The two intervention groups will be compared to a control group undergoing usual care. Cost-effectiveness analysis will be performed comparing the three groups. The study is funded from The Research Council of Norway.
Methotrexate in the Treatment of Advanced Knee Osteoarthritis With Effusion-synovitis
Knee OsteoarthritisEffusion Synovial1 moreThis multicentre randomized placebo-controlled clinical trial aims to evaluate whether methotrexate (MTX) has effects of relieving symptoms and reducing inflammation on advanced knee osteoarthritis (OA) with inflammatory phenotype. Participants will be randomly allocated to either MTX group or placebo group receiving MTX or placebo once a week. The primary outcomes are effusion-synovitis volume measured by magnetic resonance imaging (MRI) and knee pain assessed by visual analogue scale (VAS).
Stability of Contemporary Knee Arthroplasty
Knee OsteoarthritisTotal joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both total knee replacement (TKR) and total hip replacements (THR) have excellent implant survivorship. However, patient satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implants designs have been developed to solve the problem. However, most of their designs are based on experimental data and little has been studied about their actual performance in vivo. In this study, the investigators will analyze the in vivo stability of the Global Medacta Knee Sphere (GMK Sphere) implant. Migration of the implants will be monitored with a high precision measuring method called Radiostereometric Analysis (RSA). The investigators assume the investigators study will contribute the development of more satisfying knee implants.
