NCT ID: NCT03226106 Completed - Osteoarthritis Clinical Trials

Optimizing Physical Activity Outcomes After Total Knee Arthroplasty

Start date: November 15, 2017
Phase: N/A
Study type: Interventional

Although total knee arthroplasty is an effective intervention for decreasing knee pain and improving physical function, physical activity levels remain low up to a year after surgery. This study will use mobile-health technology to deliver an intervention designed to improve physical activity behavior for Veterans recovering from total knee arthroplasty. The study will assess the effectiveness of using behavior-change intervention as a supplement to conventional rehabilitation to improve physical activity. The intervention will be delivered using home-based tablet computers for Veterans to have remote interaction with the researcher and real-time physical activity feedback from a wrist-worn activity sensor.

NCT ID: NCT03215160 Completed - Clinical trials for Total Knee Arthroplasty

Using Mobilization Exercises on Total Knee Arthroplasty Rehabilitation

Start date: July 22, 2017
Phase: N/A
Study type: Interventional

There is no definite evidence about the most effective treatment approach in early-stage rehabilitation after total knee arthroplasty surgery. The purpose of this study is to investigate the effects of mobilization exercises applied with classical exercises on pain, joint range of motion, edema, function, quality of life and patient satisfaction in early stage rehabilitation after total knee arthroplasty surgery.

NCT ID: NCT03206554 Completed - Analgesia Clinical Trials

Local Infiltration Analgesia in Total Knee Arthroplasty

Start date: September 2015
Phase: Phase 2
Study type: Interventional

40 patients ASA I-III, undergoing total knee arthroplasty were randomly assigned, into one of two groups, namely group LIA (n=20), where local infiltration analgesia would be administered intraoperatively; and group sham LIA (n=20), where sham injections of normal saline would be administered. All patients received a standardized multimodal approach, including pregabalin, adductor canal peripheral nervous blockade, spinal anaesthesia, paracetamol, and PCA with morphine. Morphine consumption during the first 24 hours postoperatively was measured and additionally the investigators recorded: Time of morphine first dose administration, NRS scores in static and dynamic conditions in 6 hours, 12 hours, 18 hours and 24 hours postoperatively, complications, patient satisfaction and duration of hospitalization.

NCT ID: NCT03203967 Completed - Clinical trials for Total Knee Arthroplasty

Epidural Morphine for Postoperative Analgesia After Total Knee Arthroplasty

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Single femoral nerve blockade combined with patient-controlled intravenous analgesia are used for postoperative analgesia for patients after TKA in the hospital of the investigators. Although this method provides acceptable analgesia, the incidence of opioid-associated side effects is relatively high. Low-dose epidural morphine is commonly used in postoperative analgesia after cesarean section, and the effect of single dose morphine lasts more than 20 hours, with low incidences of itching, nausea, vomiting, and respiratory depression. The investigators hypothesize that, for patients undergoing TKA, the addition of low-dose epidural morphine to single femoral nerve block and intravenous opioids can improve the postoperative analgesia, reduce the consumption of intravenous opioids and decrease opioid-associated side effects.

NCT ID: NCT03198403 Completed - Clinical trials for Total Knee Arthroplasty

The Effect of Popliteal Plexus Block on Pain After Total Knee Arthroplasty

Start date: August 1, 2017
Phase: Phase 4
Study type: Interventional

The study aims to investigate the effect of the Popliteal plexus block (PPB) on postoperative pain after total knee arthroplasty

NCT ID: NCT03160534 Completed - Clinical trials for Total Knee Arthroplasty

Effect of Preoperative Exercise in Patients Undergoing Total Knee Arthroplasty

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

This study evaluates the effect of preoperative exercise in patients undergoing a total knee arthroplasty.

NCT ID: NCT03132077 Completed - Clinical trials for Total Knee Arthroplasty

Analysis of Patient Outcome Questionnaire Following Primary Knee Replacement

Start date: November 1, 2017
Phase:
Study type: Observational

The intention is to explore whether there are factors which help us to understand why some patient outcomes are not successful and identify prediction factors for progression. It will also assess the available outcomes pre- and post-surgery may explore prediction tools for good/poor progression and improve the patient's selection, patient preparation or timing for surgery. The focus of this project is exploring outcomes post-primary total knee arthroplasty (TKA) using the available pre/post-operative Oxford Knee Score (OKS), University of California Los Angeles (UCLA) Activity Score, EQ-5D General Health Questionnaire, Visual Analogue (VAS) for pain, age and smoking status data, and correlations between these data and post operation patient satisfaction.

NCT ID: NCT03064334 Completed - Clinical trials for Total Knee Arthroplasty

Patients' Views on Outcomes Following Total Knee Arthroplasty: a Focus-group Study

Start date: January 1, 2018
Phase:
Study type: Observational

In order to assess patients' concerns and other quality of life aspects, post-total knee arthroplasty (TKA) requires further assessment tools, more than controlled experiments testing defined isolated variables. Qualitative research offers useful methods to explicate the complexity and deeper meaning of patient experiences and outcomes post-TKA. Qualitative methods facilitate the collection of in-depth experiences and perceptions from individuals about a specific phenomenon which, in this case, is outcomes post-TKA. Specifically, a phenomenological approach allows for the collection of diverse and unique patient experiences and outcomes post-TKA . The focus of this project is using focus groups to explore poorly understood areas, such as outcomes and experiences post-TKA, in order to generate useful findings and hypotheses.

NCT ID: NCT03041857 Completed - Clinical trials for Total Knee Arthroplasty

Understanding GMK Sphere Implant Tibiofemoral Kinematics by Means of Dynamic Videofluoroscopy

Start date: December 2013
Phase: N/A
Study type: Observational

The objective of this research project is to perform a comparative study on the in vivo kinematics of the GMK Sphere prosthesis in comparison to the conventional GMK PS Fixed Bearing TKA as well as to the GMK UC Mobile Bearing during level walking, stair descent and downhill walking by means of videofluoroscopy.

NCT ID: NCT02998125 Completed - Clinical trials for Total Knee Arthroplasty

An Exploration of Outcomes Post-total Knee Arthroplasty in Middle East

Start date: March 1, 2017
Phase:
Study type: Observational

The intention is to explore whether there are factors, which can help us to understand why some patient outcomes, following total knee arthroplasty are not successful and identify prediction factors for progression. Assessment of outcomes pre- and post-surgery with objective tools is a way to explore prediction tools for good/poor progression and improve patient selection and timing for surgery. The first aim of this project is determine the psychometric properties of the Arabic Version of Oxford Knee Score, including internal consistency, reliability and validity before and post-total knee arthroplasty in both males and females in a Middle East population. The second aim is to assess the reliability of the Star Excursion Balance Test for measuring the dynamic balance. The final aim is explore outcomes post-total knee arthroplasty among Middle East patients using the Arabic Version of Oxford Knee Score, physical activity measures and performance-based measurements such as: 30 s chair-stand test, stair-climb test, timed up-and-go test and a 6 m walk test while adhering to Osteoarthritis Research Society International recommendations.
