The KinematX Midcarpal Total Wrist Arthroplasty Registry
Study Details
Study Description
Brief Summary
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.

| Arm | Intervention/Treatment |
|---|---|
| KinematX patients Patients undergoing total wrist replacement with the KinematX implant. |
Device: KinematX total wrist arthroplasty system
The KinematX total wrist implant is a joint metal/polymer semi-constrained cemented prosthesis that utilizes an articulation that mimics the midcarpal joint instead of the radiocarpal joint.

Outcome Measures
Primary Outcome Measures
- Range of Motion [Up to 10 years]
Flexion, Extension, Ulnar, Radial
Secondary Outcome Measures
- PROMIS Upper Extremity Physical Function 7a [3 months, 6 months, yearly up to 10 years post-surgery]
7 questions designed to understand the patient's physical function in the upper extremity specifically; population average t-score is 50, with a standard deviation of 10; higher scores are better.
- PROMIS Pain Interference 8a [3 months, 6 months, yearly up to 10 years post-surgery]
8 questions designed to understand how any pain experienced interferes with the patient's day to day life; population average t-score is 50, with a standard deviation of 10; lower scores are better
- PROMIS Global 10 [3 months, 6 months, yearly up to 10 years post-surgery]
10 questions to assess the patient's global health with subscales for physical health and mental health; Physical health t-scores range from 16.2 to 67.7; Mental health t-scores range from 21.2 to 67.6; higher scores are better
- Patient-Rated Wrist Evaluation Score (PRWE) [3 months, 6 months, yearly up to 10 years post-surgery]
15 questions that assess pain and function; total scores can range from 0-100; lower scores are better
- Hospital for Special Surgery Wrist Surgery Expectations Survey [Pre-operative and yearly up to 10 years post-surgery]
22 questions that assess how the patient expects to benefit from the surgery and a corresponding post-operative instrument that asks about actual experience; score range from 22 to 110; lower scores are better
- Percentage of patients experiencing post-operative complications [3 months, 6 months, yearly up to 10 years post-surgery]
- Percentage of patients requiring revision surgery for their implant (with or without implant replacement) [3 months, 6 months, yearly up to 10 years post-surgery]
- Grip and pinch strength [3months, 6 months, yearly up to 10 years post-surgery]
Grip and pinch strength
