Post-traumatic Arthritis

The goal of this study is to demonstrate the safety and performance of the Incompass™ Total Ankle System after surgery over the standard follow-up period. The study will measure improvements in patient-reported information related to quality of life and pain following surgery. In order to do this, medical imaging (i.e. X-Rays, CT scans) which have been taken as part of routine care, will be reviewed. Any additional X-Rays conducted during the period of the research will also be reviewed. The Incompass™ Total Ankle System has been cleared by the Food and Drug Administration (FDA). The products are already in use routinely in ankle replacement surgeries. No part of this study is experimental.

The objectives of the study are to confirm safety and performance of the Zimmer Nexel Total Elbow when used in primary or revision total elbow replacement.

The purpose of this study is to assess the long-term safety and performance of the LEGION Medial Stabilized insert and to generate clinical evidence to support and maintain product registration in global markets.

The goal of this observational study is to learn about functional and patient reported outcomes in patient undergoing total wrist replacement with the KinematX total wrist replacement study. The main questions it aims to answer are: * What is the range of motion (flexion, extension, radial, ulnar, grip and pinch strength) at 3-, 6-, and 12-months after surgery and yearly up to 10 years among patients having total wrist replacement with the KinematX implant. * What are the patient reported outcomes (PROMIS, PRWE, HSS wrist expectations) at 3-, 6-, and 12-months after surgery and yearly up to 10 years among patients having total wrist replacement with the KinematX implant. * How do range of motion and patient reported outcomes change over the 10 years after total wrist replacement surgery? Participants will be followed according to standard of care and preoperative and post-operative information for up to 10 years after surgery will be collected and entered into an electronic data base. Patients are eligible to enroll into the registry before or after they have had their wrist replacement surgery.
