View clinical trials related to Knee Osteoarthritis.
Filter by:Osteoarthritis (OA) is a degenerative disease affecting joint cartilage and its surrounding tissue. It is the leading cause of disability in the elderly. The treatment of this disease remains limited to symptomatic relief and, ultimately, joint replacement. Despite the progress made in understanding the pathophysiology of OA, effective disease-modifying drugs are still lacking. Low-level laser therapy (LLLT), also known as Photobiomodulation therapy, is a non-ionizing optical radiation in the visible or near infrared range of the spectrum. LLLI has been used widely for alleviation of pain, reduction of inflammation, and acceleration of wound healing. Specifically, it has been shown to reduce pain in chronic inflammatory related knee pathologies in pre-clinical and clinical studies. However, the recommended treatment protocol requires frequent treatments that translates to frequent visits at the clinic. Such a treatment regimen is difficult for Knee OA (KOA) patients and demanding of the clinical staff. Since the treatment itself can be self-applied easily, a home-use device would enable frequent treatments thereby improving patient adherence to the treatment. In a pilot study, Kruglova et al [4] reported that 2 weeks of daily treatments with the home use B-Cure laser significantly reduced pain and increased flexibility in 20 elite athletes with KOA. The purpose of the current study is to determine if B-Cure laser treatments, applied at home, by the patient or personal caregiver in a real-life situation, can reduce pain and improve functionality in patients with osteoarthritis of the knee.
Previous motion analysis studies have demonstrated excellent ability to distinguish subtle differences in gait between normal subjects and those suffering from arthritis. With proper techniques and analysis differences between osteoarthritis patient groups can be distinguished. Previous research has indicated that subjects who received a single-radius design total knee replacement have superior gait performance that those who received a multi-radius design total knee replacement. The DJO Global Empowr PS Knee System is a single-radius lateral pivot design. This design should achieve reproducible more natural knee function and improved patient outcomes and satisfaction. A motion analysis laboratory will be used to collect gait data from patients who are going to receive a Empowr PS knee device and also from age-matched control subjects. These data will be compared with data previously collected from patients who received Stryker Triathlon devices, Biomet Vanguard devices and age-matched healthy control subjects.
Pain in knee osteoarthritis (OA) represents increased pain intensity due to peripheral and central sensitivity. Pressure pain threshold (PPT) is a widely applied (used) method for measuring the magnitude of peripheral and central sensitivity in knee OA. Among several manual therapy techniques increasing PPT in knee OA, the effect of end-range mobilization has not been evaluated so far. The aim of this study was to investigate the immediate effect of end-range mobilization compared to placebo on increase of PPT and some function-related measures.
A prospective, single blinded interventional study will be conducted in the Rehabilitation Medicine Clinic, University Malaya Medical Center for a duration of 1 year. Eligible subjects will be enrolled from all referrals of chronic knee osteoarthritis, following computer-generated randomization they will be allocated to either Adductor Canal Block (intervention) or Intra-articular Steroid and Lignocaine (control) groups. The assessor is blinded to the intervention received, which will be performed by an experienced interventionist, not participating in randomization or data collection and analysis. Demographics of participants, duration of symptoms, Numerical Rating Score (NRS) pain score and Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire score will be recorded prior to injection, 1 week, 1 month and 3 months post injection. Mann-Whitney U tests and Chi-Square test of association will be used as appropriate to compare groups at baseline. Numerical Rating Scale (NRS) pre and post intervention will be analyzed using paired t-test. Functional outcome and Quality of Life (QoL) subset of Knee Injury and Osteoarthritis Outcome Score (KOOS) Questionnaire pre and post intervention will be analyzed using paired t-test as well
The purpose of this study is to test whether the use of Ropivacaine and Mepivacaine are better in terms of effectiveness, cost, and safety than Bupivacaine as regional anesthetics in elective hip or knee replacement surgery.
Backwards walking has been shown to improve balance and walking in patients who have knee Osteoarthritis. It is not known if these benefits may also be seen after surgery in patients who have had a hip or knee replacement because of Osteoarthritis. This study will look to see if it is possible to conduct a bigger study into how effective backwards walking may be after joint replacement. Patients who come to the Nuffield Orthopaedic Centre in Oxford for a hip or knee replacement will be invited. They will be placed into one of two groups at random: a group where they have a course of physiotherapy plus a backwards walking programme or a group where they have a course of physiotherapy. The physiotherapy will last for 12 weeks and those who take part will have two study assessments. The first will be before any treatment and patients will complete five measures and also be issued with a simple tick box diary to complete over the 12 weeks. The second assessment will be after the treatment and will involve the same five measures and the diaries will be collected in. Participants at this assessment will also be asked if they would like to take part in an interview for the study. This is to see what the patients thought of the study. During the study the researcher will record things such as how many patients say 'yes' to the study and how many participants drop out of the treatment, to understand if a bigger study could take place.
To accomodate dissatisfied patients with a total knee arthroplasty (TKA) and improve outcomes, several knee systems have been developed. The cemented ATTUNE TKA shows superiority over other established knee systems at short-term, abating with longer follow-up. There have been no studies reporting on the results of the uncemented version of the ATTUNE. Therefore, the main objective of the current study was to report patient reported outcome measures (PROMs), survivorship and complications associated with the uncemented ATTUNE TKA.
The purpose of the present pilot study is to evaluate, through gait analysis and rating scales, the functional outcome during the execution of motor tasks with high functional demand such as walking on an unstable surface, stair ascent and descent, maximal knee flexion under load (lunge) on a sample of 20 subjects candidates to cemented total knee arthroplasty with MP design at the Orthopedic and Traumatology Clinic 2nd of the Rizzoli Orthopedic Institute. The parameters obtained will be compared with the parameters of healthy subjects comparable by age and Body Max Index (BMI) already acquired at the Movement Analysis Laboratory of the Rizzoli Orthopedic Institute, where the study will be conducted. On the day of admission to the ward (generally the day before the scheduled surgery), the enrolled patients will undergo the evaluation scales and gait analysis at the Institute's Movement Analysis Laboratory. The patients will be operated by the team of the Traumatological Orthopedic Clinic 2nd through the implantation of a cemented total knee prosthesis MP (Evolution medial-pivot knee system, MicroPort Orthopedics). Anterior knee access with medial para-patellar capsulotomy and standard instruments will be used according to current standards of good clinical practice. In the post-operative period, patients will carry out post-surgical rehabilitation following normal clinical practice. The patients will be re-evaluated at a 6-month follow-up through gait analysis and evaluation scales on the occasion of the control visit that takes place, according to the normal clinical practice at the Institute.
This is a single-arm clinical trial to investigate the outcome of exercise-based physical therapy in people with knee osteoarthritis through the use of wearable sensors.
Comparison of surgical technique for the execution of bone resections in total knee arthroplasty. Used technique are: a non-invasive extramedullary technique (EM technique) based on the use of inertial sensors for cutting guides positioning and conventional technique (IM technique), based on the use on intramedullary stem. Our hypothesis is that the EM technique based on the use of inertial sensors leads to a reduction in the number of outliers equal to or greater than 20% compared to the outliers obtained with the conventional technique.
