Active clinical trials for "Osteoarthritis, Knee"

Rehabilitation after total knee arthroplasty is very important in terms of range of motion of the knee, muscle power, normal gait, pain control and consequently the patient's satisfaction. Convectional rehabilitation methods in assist of therapist required high demand of resources. Recently, outpatient clinic or tele-communication tool based rehabilitations were investigated and reported equivalent results. However, those methods also required group or one-to-one facing that restricted availability of the exercise. With development of the motion tracking technology, new device that gives real time feedback with augmented reality images can be used for rehabilitation in home-based setting. This study aims to compare the clinical outcomes after the rehabilitation by interactive home-based device or conventional inpatient setting.

Total knee arthroplasty is a well-known treatment of the end-stage osteoarthritis of the knee. In the case of bilateral end-stage knee osteoarthritis, both of the knees need total knee arthroplasty. Bilateral total knee arthroplasty could be performed simultaneously or staged according to the preference of the patients. Simultaneous total knee arthroplasty is defined as the replacement of both knees in a single surgery. The major advantage of simultaneous total knee arthroplasty this surgery is that it requires only one hospital stay and a rehabilitation period to recover both knees, but higher blood transfusion rates and thromboembolism risk are still major concerns. Therefore, in this comparative study, smart-phone based gait analysis and patient-reported functional outcomes are evaluated in patients undergoing simultaneous and staged total knee arthroplasty, at 3, 6, and 12 months postoperatively

This study aims to compare the clinical results of postoperative wound between Dermabond PRINEO™(2-octyl Cyanoacrylate adhesive and polyester mesh) and subcuticular suture in simultaneous total knee arthroplasty There is previous studies over whether or not to use skin adhesive material is superior or inferior to subcuticular suture This study prospectively randomized patients receiving bilateral total knee arthroplasty(TKA). Patients preference and clinical results was investigated in both knee of same patients who received skin adhesive or subcuticular suture in each knee.

The purpose of this study is to compare the efficiency of neuromuscular electrical stimulation and of resisted exercises on increasing quadriceps strength, decreasing pain and on recovering motor function of patients with knee osteoarthritis.

Many surgeons and patients prefer bilateral total knee arthroplasty (TKA) under one anesthesia as single-stage administration. A single-stage bilateral TKA can be performed in two different ways: single-stage, two-team simultaneous bilateral TKA (two surgeons bilateral TKA), and single-stage, a sequential bilateral TKA (single surgeon bilateral TKA). The purpose of this study is to evaluate the radiological results in the single-stage bilateral TKA in terms of two surgeons bilateral TKA and single surgeon bilateral TKA.

Osteoarthritis of the knee is a common problem causing significant knee pain and disability. Medial compartment osteoarthritis is predisposed to by varus deformity of the knee. High tibial osteotomy is a well-established method for treatment of medial unicompartmental knee osteoarthritis and correction of varus deformity.

The goal of this study is to evaluate a telehealth Stepped Exercise Program for Knee OsteoArthritis (STEP-KOA) among rural veterans. Methods: This is a single arm, pre-post pilot trial of the 6-month STEP-KOA program among rural Veterans with a physician diagnosis of knee OA who self-report knee pain ≥3 on a 0-10 scale and self-reported difficulty with either walking or stair climbing. We aim to enroll 20 Veterans in this project but may enroll up to 30 in order to obtain sufficient information to evaluate the program, particularly among Veterans who live in very rural areas. Assessments will be conducted via a combination of telephone and video at baseline and 2-, 4-, and 6-month follow-up. Assessments will include questionnaires related to pain, function and physical activity, as well as several physical performance tests. STEP-KOA begins with a low cost, primarily self-directed exercise program (supported by an internet-based tool; Step 1). Patients are then assessed for degree of improvement in symptoms, and then can step up sequentially to telephone or video-based physical activity coaching (Step 2) and physical therapy (Step 3) if they do not make clinically relevant improvements in prior steps. For this project, patients will be assessed approximately every 2 months to determine step progression. Participants will advance to the next step if they do not meet response criteria for pain and function established by the Outcome Measures in Rheumatology group and the Osteoarthritis Research Society International (OMERACT-OARSI). The Step 2 intervention involves bi-weekly telephone or video calls. Step 3 involves 3 telehealth PT visits, based on standard care for knee OA.

The subject is planned to carry out the clinical trails of femoral condyle prosthesis, tibial tray prosthesis and meniscus prosthesis; At the same time, in order to achieve personalized precision bone resection, the clinical trial verification is carried out on the personalized cutting guides.

The investigators randomly divided the knee osteoarthritis patients met the inclusive criteria into two groups (study group and control group). Placement of balanced buttress absorbable spacer and total knee arthroplasty were conducted. The clinical outcome of two groups were compared in this study.

In advanced knee osteoarthritis, postural stability is also disturbed. There are some concerns about performing radiofrequency ablation to genicular nerves since this may further decrease the postural stability of the patient. The aim of this study is to see if application of genicular radiofrequency causes a significant change in postural stability.
