This implant has already been tested and been approved by the FDA and is already in use routinely in total ankle replacements within the United States. We are conducting this study to gain further knowledge about the implant. In order to do this, x-rays which have been taken as part of your routine care will be reviewed. Any additional x-rays conducted during the period of the research will also be reviewed. We are also interested in measuring improvements in patient-reported information related to quality of life and pain following implantation over a 10-year period.

This study will consist of patients 12 years and older undergoing ACL reconstruction using a quadriceps or bone-patella tendon bone (BTB) graft. The patients will be randomized to adductor canal block alone, or adductor canal block + iPACK block. The primary goal will be to determine the differences in postoperative pain during the first 72 hours when comparing the two groups. Secondary outcomes will include opioid utilization during the first 72 hours postoperatively and range of motion including terminal knee extension at postoperative follow-up visits.

Patients of age ≥40 to <85 years diagnosed with a rotator cuff tear (with MRI confirmation) who are fit for either arthroscopic rotator cuff surgery or physical therapy will be recruited. The study will compare pain and function in patients undergoing operative versus non-operative treatment of Non traumatic rotator cuff tears at 12 months of follow-up.

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.

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.
