Active clinical trials for "Osteoarthritis, Knee"

Muscular (i.e., quadriceps) weakness is a major risk factor for predisposing the knee to osteoarthritis, impairing physical function, and increasing patient-reported pain. Muscular weakness is a consequence of and could contribute to the development of knee osteoarthritis. Minimizing muscular weakness has been fount to improve activities of daily living in patients with osteoarthritis symptoms. Although vitamin D associates with muscular strength in young and old populations, it is unknown if vitamin D supplementation improves muscular strength in subjects with osteoarthritis or osteoarthritis symptoms. It is also unknown if supplemental vitamin D alters circulating cytokine concentrations in subjects with knee osteoarthritis. Furthermore, it is probable that a more comprehensive supplement is necessary to improve muscular strength. Such as glucosamine sulfate and omega-3 fatty acids (i.e., eicosapentaenoic and docosahexaenoic acids) which could be influential on knee pain and inflammation as well as muscular strength. Therefore, the purpose of this study is to identify the influence of vitamin D supplementation with and without glucosamine sulfate and omega-3 fatty acids on circulating cytokine concentrations and muscular strength in subjects with knee osteoarthritis symptoms. This study is intended to establish preliminary data identifying the influence of vitamin D supplementation on circulating cytokines and muscular strength in subjects with osteoarthritis at no more than minimal risk exposure to subjects.

Compare OR resource use and clinical Outcome after Total Knee Arthroplasty using Patient-specific or conventional Instrumentation.

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.

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.

Previous retrospective database studies suggest that total knee arthroplasty (TKA) surgery under spinal anesthesia has less complications than when performed under general anesthesia. In general, complications are rare and both anesthesia types are widely accepted. In Finland, total knee arthroplasty has typically been performed under spinal anesthesia. In a recent prospective randomized controlled study, total knee arthroplasty under general anesthesia resulted in less acute postoperative pain (opioid-need measured by patient-controlled anesthesia), less nausea, and faster hospital discharge than that performed under spinal anesthesia. Also the use of surgical tourniquet can affect surgical outcome: it may reduce bleeding and surgery time, but it may also cause weakness of thigh muscles and thus hinder mobilization. In a recent study, both techniques with and without surgical tourniquet appeared equal. The aims of this study are to compare total knee arthroplasty under spinal or general anesthesia, with or without surgical tourniquet, in relation to acute and chronic postoperative pain, nausea, knee function, patient reported quality of life and satisfaction on care, complications, length of stay, and need of surgical unit resources. This randomized controlled study includes 400 patients with informed consent, 18-75-years-of-age, standard primary total knee arthroplasty operation, American Society of Anesthesiologist (ASA) physical status classification I-III, body mass index under 40, and no contraindications for medications or treatments used. The hypothesis of this study are used to reassess best practices of primary total knee arthroplasty operation to enhance quality of care, patient outcomes and satisfaction, and availability of surgery due to better patient flow at surgical unit.

The present study was carried out on thirty patients with primary knee osteoarthritis. Patients were recruited from Rheumatology and Rehabilitation Outpatient Clinic at Mansoura University Hospi Patients were divided into two groups: Group 1: included 15 patients who received oral strontium ranelate and physiotherapy program. The age of the patients ranged from 50 to 62 years, they were 11 females and 4 males. Group 2: included 15 patients who received physiotherapy program. The age of the patients ranged from 50 to 62 years, they were 12 females and 3 males. Written consent was obtained from each participant sharing in the study. This study was approved by the institution research board of faculty of medicine, Mansoura University, code: MS/15.10.08. Inclusion

the study was conducted on 31-patients with symptomatic primary knee osteoarthritis. The patients were randomized into intervention and control groups. The control group was kept on their medications without intervention. The intervention group received two doses of allogenic lyophilized growth factors (L-GFs); at baseline and after 2 months.

There are concerns that total infrapatellar fat pad (IPFP) excision in total knee arthroplasty (TKA) results in patellar tendon shortening due to ischemic contracture. But, individual preference of the surgeon is still the main determinant between total or partial excision. The aim of this randomized controlled trial is to compare knee society score (KSS), knee extension and flexion peak torque in patients undergoing TKA with total IPFP excision or partial IPFP excision. The hypothesis of the study is that during TKA, total IPFP excision would lead to worse isokinetic performance and clinical outcome. A total of 72 patients scheduled to undergo TKA for primary osteoarthritis of the knee by a single surgeon were randomly assigned to either the total or partial excision group. Patients were evaluated preoperatively and at postoperative 1 year, with Knee Society Score (KSS) and isokinetic measurements. Physiatrist doing isokinetic tests and patients were blinded to the study.

For decades there have been concerns about patellar resurfacing (PR) in total knee arthroplasty (TKA) and the individual preference of the surgeon is still the main determinant of whether or not resurfacing is applied. According to preference, surgeons can be categorized in 3 main groups of those who usually, selectively or rarely resurface. The aim of this prospective, randomized, controlled study to is compare the isokinetic performance and clinical outcome of TKAs with PR and without PR.

The aim of this observer-blinded randomized controlled trial is the evaluation of the influence of manual lymphatic drainage (MLD) on the outcome of patients receiving total knee replacement (TKA).
