Filter by:Postoperative cognitive dysfunction (POCD) occurs mainly in aged patients. POCD may increase the mortality and morbidity. However, the mechanism of POCD is not clear yet and no effective therapy method was proved. According to our previous study, the central cholinergic system impaired by the anesthesia and surgery play a very important role in the POCD and donepezil an acetylcholinesterase inhibitor can prevent the POCD after isoflurane anesthesia in aged mice. Donepezil is a commercial medicine used for the Alzheimer Disease, which is tolerable and has minimal adverse events. In present study a multi-center randomized case control study was conducted and we hypothesized that donepezil attenuate the POCD.
This study evaluates the effect of the single-injection adductor canal block in patients receiving total knee arthroplasty under spinal anesthesia.
Background Blood flow restriction training (BFRT) uses a specialized tourniquet system to restrict arterial inflow and venous outflow to the limb during low-load resistance exercise. BFRT has the potential to augment strength gains for rehabilitation patients who are unable to tolerate high intensity resistance training. Objective To determine if BFRT will accelerate the recovery of thigh muscle function and strength in post-operative TKA compared to a standard post-operative rehabilitation protocol. Primary Outcome Measures: Quadriceps Strength: dynamometry (hand held) Secondary Outcomes Measures: Patient Reported Outcomes Knee Injury and Osteoarthritis Outcome Score, Jr Veterans Rand -12 Functional Measures Timed stair ascent Four square Test 5x Sit to Stand Test Study Design Open label randomized clinical trial with a 1:1 allocation in random sized blocks Sample Size Based on a Pre-TKA Quadriceps Maximal Voluntary Isometric Contraction mean of 18 with a standard deviation of 8, expecting a 20% improvement of MVIC with BFRT compared to standard Physical Therapy, with an α of 0.05 and β of 0.20 (80% power), the sample size is 63 in each arm. To account for a 20% drop-out rate, a total of 75 subjects will be enrolled in each arm Study Arms Control arm: Subjects will receive American College of Sports Medicine guided-strength training Experimental: Subjects will receive BFRT strength training as part of their post-operative physical therapy program for two months during normal post-op rehab.
The purpose of this feasibility study is to determine the initial efficacy of early combined Neuromuscular Electrical Stimulation (NMES) and Blood Flow Restriction (BFR) in addition to standard rehabilitation in 15 subjects after Total Knee Arthroplasty (TKA). The second aim is to determine the feasibility and patient perceptions of combined NMES and BFR by assessing: 1) adherence, 2) satisfaction and 3) safety.
The purpose of this study is to gather information about how knee pain changes when small amounts of electricity are delivered to the nerves in the leg. This study will involve the use of a Peripheral Nerve Stimulation (PNS) System that is made by SPR Therapeutics (the sponsor of the study). The SPRINT PNS System was cleared by the FDA for up to 60 days of use in the back and/or extremities for the management of acute and chronic pain.
The purpose of the study is to acquire kinematic in vivo fluoroscopy data from subjects who were implanted with Stryker Posterior Cruciate Retaining (PCR) , Stryker Posterior Stabilized (PS), Zimmer PCR, and Zimmer PS Total Knee Arthroplasty (TKAs). Our lab has previously collected data for the Smith & Nephew PCR, bi-cruciate retaining (BCR), and bi-cruciate stabilized (BCS) TKA.
Total knee arthroplasty post-op surgical site infection rate about 0.5- 5% Pre-operative , perioperative and post-operative prevention are importance for reduce surgical site infection The prevention of surgical-site infections (SSIs) is an integral component of nosocomial infection control and a major priority in orthopedic surgery. Surgical wound contamination must be prevented to avoid patient colonisation by microorganisms during surgery. Surgical glove changing perioperative can reduce contamination and perforation rate Orthopedic surgery had found contamination rate about 20-28 % Joint replacement procedure found contamination rate about 38-67% of all orthopedic surgery 12% of gloves are contaminated after draping and 24% once patient installation is complete. We hypothesis that changing surgical glove during total knee arthroplasty can reduce contamination rate on surgical glove.

Significant trauma and muscular tightness often result during Total Knee Arthroplasty (TKA) surgery and thus act to restrict tissue fluid movement resulting with lower extremity edema. Kinesio Taping® is applied directly on the skin for restoration of normal fluid perfusion, removing congestion of lymphatic fluid or hemorrhages. In addition Manual Lymphatic Drainage (MLD) enhances blood circulation and stimulates the lymphatic movement and unblocks lymphatic territories. The aim of the study was to investigate the effectiveness of Kinesio Taping® and MLD in reducing postoperative edema and pain in the early stage after TKA.
The purpose of this study is to evaluate performance of two modern total knee arthroplasty designs using patient reported outcomes and force exhibited during various activities of daily living.
