Filter by:The aim of this study is to assess the safety of Stemedica's mesenchymal stem cells in patients with knee osteoarthritis. The route of administration is intraarticular. Safety will be evaluated by AE/SAE incidence and administration tolerance. The subjects will undergo follow-up for 52 weeks. The target population is subjects with knee osteoarthritis (grade II-III in Kellgren-Lawrence scale).
Osteoarthritis (OA) is one of the most frequent causes of chronic pain, often intense, debilitating and responsible for a large percentage of the elderly. The disease affects about 10% of adults and the knees are the most affected joints. The diagnosis of OA in the knee is predominantly clinical, and can be confirmed by radiological examination. Systemic drugs are indicated before invasive procedures, but pharmacological therapies may offer limited benefits. Thermal radiofrequency lesions of genicular nerves has been used to relieve chronic knee pain, as adjuvant therapy, but with high costs and low availability in the public system. The use of phenol for peripheral analgesic blocks has emerged as a good option and at low cost and can be used in any service of Pain Treatment. The aim of the study is to evaluate the efficacy of 6% phenol for ultrasound-guided genicular nerves neurolysis for the treatment of patients with chronic knee pain due to osteoarthritis. METHODS: A prospective study will be carried out with 15 patients with chronic pain (more than 4 months) and diagnosis of arthrosis by imaging, with pain intensity greater than 4 (from zero to 10) that will be submitted to ultrasound-guided genicular nerves block. The test block will be performed with 0.25% -1,5 mL bupivacaine on each nerve. Patients who present pain improvement> 50% will undergo neurolysis of genicular nerves with 1,5 mL of 7% phenol in each of the genicular nerves. After the procedure, the patients will be evaluated for 3 months in relation to the intensity of pain at rest and movement and duration of analgesia provided by the intervention, range of movements and functionality of the knee joint.
The overall goal of this study is to demonstrate the safety and efficacy of Hydroxycoll bone graft substitute when used in the treatment of patients undergoing surgical treatment for varus mis-alignment in medial unicompartmental osteoarthritis of the knee. HydroxyColl bone graft substitute will be evaluated when utilized in Open Wedge High Tibial Osteotomy with medial plate fixation. Its safety profile will be evaluated as defined by the number of reported adverse events.
In order to investigate the difference of intra-articular hyaluronate's distribution and compare the clinical outcomes of viscosupplementation for mild-to-moderate knee osteoarthritis (mKOA) between the anteromedial (AM) and medial midpatellar (MMP) approach groups. This study included two parts, cadaver study (n=64) and random controlled trial (n=100). Hyaluronic acid (HA) traced by methylene blue was injected into the knee, and the intra-articular distribution of HA was assessed using a five-point scale in the cadaver study. The clinical outcomes of 5-weekly injections of HA were evaluated by WOMAC and Lequesne index and the follow-up times were at weeks 1, 2, 3, 4, 5, 14, and 24 after the injections in the random controlled trial.
Based on the research background and the preliminary research basis of the research group, in order to answer the material basis and micro-physical environment change characteristics of knee osteoarthritis sensitization acupoints and provide scientific basis for in-depth study of sensitization of acupoints. This study plans to use knee osteoarthritis as a research vehicle, and use microdialysis combined with high performance liquid chromatography to analyze the local material basis and key indicators of common sensitization points in knee osteoarthritis.
This research is being done to see if the amount of an enzyme in blood (called serum mast cell tryptase) changes before and after surgery. The investigators would like to see if these amounts are related to knee stiffness and pain in subjects that undergo a total knee replacement.
This study is a phase 2, 52-week international, multi-regional, multi-center, randomized, double-blind, placebo-controlled dose-ranging study for the treatment of osteoarthritis.
The Clinical trial is a phase I/IIa clinical study for treatment of knee osteoarthritis by intra-articular injection of bone marrow derived allogeneic mesenchymal stem cells. Primary endpoint of the study is safety of allogeneic BM-MSCs application on knee OA with single dose IA injection and the MTD. Secondary endpoint is the effect of allogeneic BM-MSCs transplantation including clinical and image observation since the MSCs have multi-lineage differentiation potential such as chondrocyte differentiation, anti-inflammation and immune-modulation.
Sixty patients with a diagnosis of knee osteoarthritis, aged between 40 and 80 years, of both genders were included. The patients were divided into: experimental group that carried out an educational program - 5 consecutive sessions held once a week, with a duration of 60 minutes each class and at the end of the last class, a booklet was delivered for each patient with all the contents of the classes and the Transcutaneous Nerve Electro-Stimulation device - being performed twice weekly, for 5 weeks for 40 minutes each session; and control group who only underwent treatment with the Transcutaneous Nerve Electro-Stimulation in the same parameters as experimental group. The evaluations were performed at the beginning of the treatment, 4 and 12 weeks after the beginning of the treatment using a numerical pain scale; WOMAC; IDATE and SF-36 questionnaires; and 6-minute walk test.
This study is a randomized, single blind, controlled trial. Aim to compare the effectiveness (especially the absorption degree of the synovial effusion measured by B ultrasonic) of the treatment group with the control group. The treatment group was given Xiao zhong fang granules orally and short wave infrared radiation and the control group was given the placebo Xiao zhong fang granules orally and short wave infrared radiation. To evaluate the clinical efficacy of the Chinese medicine in the treatment of the synovial effusion of knee osteoarthritis.
