The purpose of this study is to determine whether a new medical technology can help reduce post-operative total knee or hip pain when combined with a Cognitive-Behavioral intervention (CBI).
This new medical technology, is called transcranial direct current stimulation (tDCS), it uses a very small amount of electricity to temporarily stimulate specific areas of the brain thought to be involved in pain reduction. The electrical current passes through the skin, scalp, hair, and skull and requires no additional medication, sedation, or needles.
This study will investigate the effects of tDCS, the Cognitive-Behavioral (CB) intervention and their combination on pain among veterans following total knee arthroplasty (TKA) or total hip arthroplasty (THA). You may benefit in the form of decreased pain and opioid requirements following your knee or hip replacement surgery. However, benefit is only likely if you are randomized to one of the 3 (out of 4) groups.
This study hopes to determine the effects of these interventions and their combined effect on post-operative pain, opioid use and functioning during the 48-hour post-operative period following a total knee or hip replacement.
Patients who present with a native joint complaint and consent for the study will be tracked and their standard of care data will be monitored for outcomes of a septic joint. There are no additional actions taken outside of the standard of care. The results after the subject goal has been met will allow us to have a better understanding of the criteria for a septic joint.
PEPPER is a randomized study comparing the three most commonly used blood thinners in North America in patients who have elected to undergo primary or revision hip or knee joint replacement surgery. The blood thinners being compared are enteric coated aspirin plus air pump compression, low intensity warfarin, and rivaroxaban.
The study will collect data to further affirm the safety and effectiveness of the Optetrak® Knee System product lines. Data will be collected in order to provide post-market subjective and objective evidednce of safety and effectivness. Data may be analyzed to support future presentation and publication of the Optetrak® Knee Systems and will be made available in the event Exactech is required to provide clinical evidence of the post market outcomes of the Optetrak Knee devices.
The purpose of this study is to collect and evaluate clinical and radiographic outcomes data on patients who have undergone, or will undergo, shoulder replacement surgery. Patients who receive a device from the Equinoxe® Shoulder System, manufactured and distributed by Exactech, Inc as well as patients who receive a device from another shoulder arthroplasty system may be included in this study.
To collect data to further affirm the safety and effectiveness of the hip replacement systems manufactured and/or dustrubuted by Exactech, Inc. Data will be collected in order to provide post-market subjective and objective evidence of safety and effectivenss. Data may be analyzed to support future presentation and publication of theses systems and will be made available in the event Exactech is required to provide clinical evidence of the post market outcomes of the devices.
