5. Study Description

Brief Summary
The aim of this first study is to investigate in a case series through sequential sonographic imaging, using Doppler ultrasonography, the postoperative morphology, especially vascularity and findings of neovascularity, after bursa augmentation in arthroscopic rotator cuff repair.
Detailed Description
The outcome of rotator cuff (RC) reconstruction with and without bursa augmentation, considering also the inflammatory status of the bursa, will be systematically investigated for the first time. The influencing role of the inflammatory status of the bursa, of the RC tendon and the synovial membrane at the time of the operation on the tendinous healing rate, the patient-relevant outcome factors and the revision rate will be assessed. In a further approach, basic knowledge about the role of bursa inflammation and its influence in the development and regeneration of tendon pathologies shall be gained. The findings of the whole project could lead to improve tendon healing in the reconstruction of the rotator cuff, taking advantage of augmentation potential of the subacromial bursa.
