condition that would pre-empt their ability or willingness to participate in the study
including mental illness, mental retardation, and drug or alcohol abuse.

- Subjects who do not meet the indication or are contraindicated according to specific
Smith+Nephew REGENETEN System's Instructions for Use (IFUs).

- Any subject that meets the definition of a Vulnerable Subject per ISO 14155 Section

Summary
Brief summary
The purpose of the study is to assess whether the REGENETEN™ Bioinductive Implant allows
patients to get back to their everyday activities quicker than if the tendon is repaired by
the standard repair technique 'Completion and Repair' for surgically treating
partial-thickness rotator cuff tears.
