This study checks if the REGENETEN™ Bioinductive Implant System helps patients recover faster than a traditional way to fix shoulder tendon tears. Tendons are tissues that connect muscles to bones. In this study, people with high-grade partial-thickness tears, which means over 50% of the tendon is torn, will be treated. The study compares two methods: Isolated Bioinductive Repair (IBR) and Completion and Repair (CAR).

To join, you must be over 18, have a specific type of tendon tear, and have tried other treatments for at least 3 months without success. You also need to be able to attend all study visits and follow instructions. Some people cannot join, such as those with certain shoulder conditions, recent surgeries, or allergies to certain materials. The study will look at how well patients can use their shoulder after 3 months.

• Study duration is 3 months.
• Participants must attend all study visits.
• It's important to follow instructions and complete all questionnaires.
