PARQVE Prior to Total Knee Replacement

Start date: August 1, 2019
Phase: N/A
Study type: Interventional

Introduction: Elderly patients, the majority of the population submitted to total knee arthroplasty (TKA), have a lower capacity for adaptation to hospitalization and surgical stress. Exercise before cardiac and abdominal elective surgery was shown to reduce the number of complications. Studies have shown that preoperative exercise improves functional performance, strength and may decrease hospital stay after an ATJ. Objective: To evaluate if the program exercises before TKA improves quality of life, function, pain and body composition, time of hospitalization and number of complications of patients submitted to TKA. Methods: 44 patients awaiting TKA in IOT-HC-FMUSP will be divided into two groups. Half of the patients will undergo a multiprofessional and physical activity educational program for 20 weeks while the other half will wait for the TCA in the outpatient clinic. Patients will be evaluated through functional tests (sit-up and 30-second tests and time up and go), standardized questionnaires (WOMAC and Lequesne), quality of life scales (Euroqol-EQ-5D-5L), pain (through VAS), body composition and bone density (through densitometry), time of hospitalization and complications resulting from TKA. All of the above parameters will be assessed at baseline and 1 and 6 months after TKA. All project costs will be reported and a cost-effectiveness and cost-utility analysis will be performed.

New Application of Buprenorphine Patch on Painful Knee Joint in Knee Osteoarthritis Patients

Start date: May 15, 2019
Phase:
Study type: Observational

Osteoarthritis (OA) is already one of the most disabling diseases in developed countries. Intra-articular (IA) injection of opioid in joints has been widely studied for its simplicity, safety and efficacy. We suggest the method of opioid patch regional application to OA patients instead of intra-articular opioid injections. We had applied buprenorphine patch to painful knee joint in knee OA patients, and compared knee application with conventional chest application for analgesic effects, adverse effects and compliance of buprenorphine patch. We willl retrospectively enroll about 200 patients with knee OA who did not respond to conventional therapy. Numeric rating scale (NRS), adverse effects, and compliance were checked and recorded before and after buprenorphine patch applied. All parameters were compared between chest applied group and knee applied group.

Immediate Effects of Proximal and Distal Acupoints on the RPPW in Patients With KOA: a Randomized Controlled Trial

Start date: April 30, 2019
Phase: N/A
Study type: Interventional

Introduction: Knee osteoarthritis (KOA) is the most prevalent joint condition and is characterized by the progressive erosion of the articular cartilage. In TCM, Pulse Diagnosis has been one of the key diagnostic components in the clinical examinations. Modern pulse diagnosis studies have found that when the human body develops disease or is under pressure, the high frequency spectral energy (10-50Hz) will significantly change. Augmentation index (AIx) is related to the wave reflection of blood vessels. AIx can function as a useful index to reveal aging blood vessels. The experiment will use spectral energy and AIx as objective judgments about the efficacy of before-acupuncture and after-acupuncture treatment. Method: This randomized controlled study will recruit 120 participants which will be allocated to 3 groups: Distal Acupoints, Proximal Acupoints and Sham Acupoints. Each group will have 40 participants to ensure a sufficient sample size can be attained for statistical analysis. Participants aged 20 or older with acute or chronic arthritis will be recruited when they meet the Clinical Classification Criteria for KOA, that is knee pain and three out of six symptoms can be found in clinical practices, as recommended by the American College of Rheumatology:(a) any gender aged 50 years or above;(b) have less than 30 mins of morning stiffness ; (c) crepitus on active motion; and (d)bony tenderness;(e)bony enlargement; and (f)no palpable warmth.Objective and subjective baseline assessments and outcome evaluations including VAS, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and range of knee motion will be performed. The primary outcome will be the assessment of Spectral Energy and AIx of radial pressure pulse-wave in both wrists (Chun, Guan, and Chy pulse) using the Pulse Sphygmograph before and after the intervention. The secondary outcome involves evaluating VAS and range of knee motion. Expected Outcome: The research findings can be clinical evidence regarding the effect of acupuncture KOA on radial artery. Moreover, the research will explore the immediate-effect difference between distal and proximal acupoints on KOA.

Pre-emptive Effect of Duloxetine in the Second Knee in Staged Total Knee Arthroplasty

Start date: January 2019
Phase: Phase 4
Study type: Interventional

In Korea, the interval between knee arthroplasties is usually 1 week. According to previous studies, when total knee arthroplasty was performed at 1-week intervals, total bleeding was reduced and the period of hospital stay was shortened. However, if stepwise total knee arthroplasty is performed at intervals of one week, the pain is greater after the second operation, and the reason for this phenomenon is known to be due to central sensitization and opioid resistance. Therefore, the investigators aim to confirm whether Duloxetine reduces the central sensitization as previously known and affects the pain control after the second operation.

Lower Knee Joint Loading by Real-time Biofeedback Stair Walking Rehabilitation for Patients With MCKOA

Start date: January 1, 2021
Phase: N/A
Study type: Interventional

This study will establish a machine-learning algorithm to predict KAM using IMU sensors during stair ascent and descent; and then conduct a three-arm randomized controlled trial to compare the biomechanical and clinical difference between patients receiving a course of conventional laboratory-based stair retraining, sensor-based stair retraining, and walking exercise control (i.e., walking exercise without gait retraining). The investigators hypothesise that the wearable IMUs will accurately predict KAM during stair negotiation using machine-learning algorithm, with at least 80% measurement agreement with conventional calculation of KAM. The investigators also hypothesise that patients randomized to the laboratory-based and sensor-based stair retraining conditions would evidence similar (i.e., weak and non-significant differences) reduction in KAM (primary outcome) and an improvement of symptoms (secondary outcomes), but that these subjects would evidence larger reductions in KAM than subjects assigned to the walking exercise control condition.

Preoperative CT Assisted Planning for Primary Total Knee Arthroplasty

CT planning
Start date: September 2018
Phase: N/A
Study type: Interventional

Total knee arthroplasty is one of the most common management methods of knee osteoarthritis. Patellar complications are one of the important causes of revision total knee arthroplasty. Proper placement of the components in the best rotational and axial alignment would achieve better patellar tracking and the best functional outcomes. Preoperative CT scan can add information regarding the coronal and rotational alignment of the prosthesis components.
