This study is a Post Market Clinical Follow-up study to fulfill the post market surveillance requirements. The data collected from this study will serve the purpose of confirming safety and performance of the TESS Shoulder System.
The objective of this retrospective and prospective, multicenter, non-controlled Post Market Clinical Follow-up study is to evaluate the mid-term (5-year) clinical performance of the TESS Version 2 Anatomic and Reverse prostheses in shoulder arthroplasty. The primary outcome is defined as the clinical performance determined using Constant Score. The secondary outcomes are the passive and active mobility, the radiographic evaluation, the complications (including dislocation and revisions/removals) and survivorship.

Constant Shoulder Score
The Constant Murley score is a multi-item scale assessing the level of pain and the ability to carry out the normal daily activities of the patient. The test is divided into four subscales: pain (0-15 points), activities of daily living (0-20 points), strength (0-25 points) and range of motion: forward elevation, external rotation, abduction and internal rotation of the shoulder (0-40 points). The results are here reported as final score, which ranges from 0 to 100, with 0 representing the worst and 100 the best shoulder function.
Time frame: Pre-operative, 5 years follow-up
Active Anterior Elevation
The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active anterior elevation measures the extent to which a patient can elevate the arm anteriorly and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Active Lateral Elevation
The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active lateral elevation measures the extent to which a patient can elevate the arm laterally and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Active External Rotation RE1
The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active external rotation RE1 measures the extent to which a patient can rotate the bent arm externally and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Active External Rotation RE2
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active external rotation RE2 measures the extent to which a patient can rotate the arm externally from a position of 90° of abduction and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Passive Elevation
The passive mobility is measured with 2 movements: elevation and external rotation elbow to body (RE 1). Passive elevation measures the extent to which the arm of the patient can be passively elevated in the plane of the scapula and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Passive External Rotation
The passive mobility is measured with 2 movements: elevation and external rotation elbow to body (RE 1). Passive external rotation elbow to body (RE 1) measures the extent to which the bent arm of the patient can be passively rotated externally and is here reported in degrees.
Time frame: Pre-operative, 5 years follow-up
Radiographic Evaluation
A complete radiographic evaluation (front view 3 rotations, lateral view) is completed pre-operatively. For the post-operative radiographic evaluations, the form is simplified and contains two options: "unchanged" or "changed" when compared to the preoperative x-ray, with presence of radiolucencies and/or notching. The number of "changed" radiographic evaluations per time point are here reported.
Time frame: Immediate post-operative, 6 weeks follow-up, 6 months follow-up, 1 year follow-up, 2 years follow-up, 3 years follow-up, 4 years follow-up, 5 years follow-up.
Survivorship
The Kaplan-Meier method is used to report implant survivorship. This outcome measures survivorship of the implanted devices from the date of implantation to the date of revision or intended revision up to 5 years post-operatively.
Time frame: 5 years follow-up
