This is a research study to find out whether patient characteristics such as BMI, strength, age, gender, and hand dominance are associated with range of motion in patients with healthy shoulders. It is hoped this information will better help us understand what affects motion and strength in the healthy shoulder providing a useful control in evaluating clinical outcomes in a diverse group of patients by age presenting with shoulder pathology. This will ultimately allow us to better counsel patients undergoing shoulder surgery regarding expectations for improvements in range of motion and strength by age postoperatively.
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.
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.
