Overview

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.
