Clinical Trials

The purpose of this study is to determine the upper limb movement and control strategies for older adults with a rotator cuff tear and to compare how they may be different from measures from older adults without a rotator cuff tear.

Our goal is to determine if the stiffness of supraspinatus muscle can be measured non-invasively before surgery, using ultrasound B-mode together with a new ultrasound technique called Shear Wave Elastography (SWE). The hope is that this assessment of muscle stiffness before surgery will help the doctors to plan the best surgical approach.

The purpose of this study is to determine whether a diagnostic reconciliation conversation aid can assist a shared decision-making conversation between patients and clinicians to reach a consensual diagnostic plan of care and confirm that patients and clinicians have the same understanding of its goals, nature (including patient experience), and downstream consequences (including implications for further testing and treatment).

The purpose of this study is to compare pain and function in patients undergoing operative versus non-operative treatment of atraumatic rotator cuff tears at 12 months of follow-up, and to assess effects of rotator cuff tear size and age on comparative outcomes of operative versus non-operative treatments for atraumatic rotator cuff tears.

The purpose of this study is to:

• Evaluate the influence of the critical shoulder angle (CSA) on outcomes after total anatomic shoulder arthroplasty; and
• Evaluate the influence of the critical shoulder angle (CSA) on rotator cuff failure after total anatomic shoulder arthroplasty.

Pre-operative perineural injection of dexamethasone mixed with local anesthetic in peripheral nerve blockade for orthopedic surgery has been shown to prolong the length of analgesia, improve visual analog pain scores, decrease post-operative opioid use, and decrease post-operative nausea. No study has been published to determine if this effect is a result of systemic absorption of dexamethasone or is a local effect of the drug on neuronal activity at the injection site.

This study is a prospective, randomized, double-blind, controlled study to compare pain block with

1. ropivacaine and saline plus intravenous saline vs
2. ropivacaine and dexamethasone plus intravenous saline vs
3. ropivacaine and saline plus intravenous ...

Aims, purpose, or objectives

Aim 1: To quantify passive stiffness modifications due to RSA in deltoid muscle.

Aim 2: To interpret these modifications in the light of postoperative clinical outcomes.

The purpose of this study is evaluate the outcomes and complications in patients who underwent a rotator cuff repair.

The purpose of this study is to assess two accelerated rehabilitation programs for use with the InSpace™ device in the treatment of full thickness Massive, Irreparable Rotator Cuff Tears (MIRCTs) performed during an arthroscopic procedure.  

The purpose of this study is to evaluate safety and efficacy and show non-inferiority of the investigational PERFORM Stemless Reverse device to the control PERFORM Stem Reverse device in subjects who are candidates for the treatment of noninflammatory degenerative joint disease (i.e., osteoarthritis), avascular necrosis, pseudoparalysis or anterior superior escape, rotator cuff tear arthropathy, correction of functional deformity, and post-traumatic arthritis.
