Augmentation of Arthroscopic Rotator Cuff Repair With Reimplantation of Subacromial Bursa Tissue and Platelet-Rich Plasma
ΕΝΙΣΧΥΣΗ ΑΡΘΡΟΣΚΟΠΙΚΗΣ ΣΥΡΡΑΦΗΣ ΣΤΡΟΦΙΚΟΥ ΠΕΤΑΛΟΥ ΜΕ ΕΠΑΝΕΜΦΥΤΕΥΣΗ ΙΣΤΟΥ ΤΟΥ ΥΠΑΚΡΩΜΙΑΚΟΥ ΘΥΛΑΚΟΥ ΚΑΙ ΠΛΑΣΜΑΤΟΣ ΠΛΟΥΣΙΟΥ ΣΕ ΑΙΜΟΠΕΤΑΛΙΑ
The goal of this observational study is to evaluate the clinical and radiographic outcomes of the biological enhancement of the arthroscopic rotator cuff repair with stem cells from the acromial bursa and PRP in individuals who undergo arthroscopic cuff repair The main question it aims to answer is:
Do the stems cells from the acromial bursa and PRP promote healing and produce better results in arthroscopic cuff repair? Researchers will compare this population to three others the first do bnot receive any biological enchancement, the second receive only stem cells and the third receive only PRP to see if there are any differences.

Beschreibung
Inclusion Criteria Adult patients aged ≥18 years. Patients undergoing arthroscopic rotator cuff repair. Patients with a full-thickness, isolated, primary tear of the supraspinatus tendon.
Patients considered eligible for arthroscopic rotator cuff repair using suture anchors.
Ability and willingness to provide written informed consent. Willingness and ability to comply with the study protocol and scheduled follow-up visits.
Exclusion Criteria Partial-thickness rotator cuff tears. Massive or irreparable rotator cuff tears. Revision rotator cuff repair. Concomitant tears of the subscapularis tendon, infraspinatus tendon, long head of the biceps tendon requiring surgical treatment, or glenoid labrum.
Previous surgery on the affected shoulder. Glenohumeral osteoarthritis or advanced cuff tear arthropathy. Active infection or systemic inflammatory disease affecting the shoulder. Use of other biological augmentation techniques during surgery, such as collagen patch, stem cells, bone marrow aspirate concentrate, or other scaffold-based augmentation.
Inability to provide informed consent. Inability or unwillingness to comply with the postoperative rehabilitation protocol or follow-up schedule.

The primary outcome measure will be the functional outcome of the shoulder assessed using the Constant-Murley Score and the American Shoulder and Elbow Surgeons (ASES) score at 3, 6, and 12 months postoperatively.
Both scores are validated instruments evaluating pain, daily activities, and shoulder function, with higher scores indicating better clinical outcomes.

|
Rotator Cuff Tendon Integrity Assessed by MRI (Sugaya Classification)
Zeitfenster: 12 months postoperatively
|
Tendon integrity will be evaluated using magnetic resonance imaging (MRI) at 12 months postoperatively.
Repair integrity will be classified according to the Sugaya classification system and categorized to assess healing or re-tear.
|
12 months postoperatively
|
|
Pain Intensity Assessed by Numeric Rating Scale (NRS)
Zeitfenster: 3, 6, and 12 months postoperatively
|
Postoperative pain will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain), at 3, 6, and 12 months postoperatively.
|
3, 6, and 12 months postoperatively
|
|
Health-Related Quality of Life Assessed by SF-12
Zeitfenster: 3, 6, and 12 months postoperatively
|
Quality of life will be evaluated using the 12-Item Short Form Health Survey (SF-12) at 3, 6, and 12 months postoperatively.
The questionnaire provides physical and mental health composite scores.
|
3, 6, and 12 months postoperatively
|
|
Patient Satisfaction
Zeitfenster: 3, 6, and 12 months postoperatively
|
Patient satisfaction will be assessed using a Numeric Rating Scale from 0 to 10 at 3, 6, and 12 months postoperatively, with higher scores indicating greater satisfaction.
|
3, 6, and 12 months postoperatively
|
|
Postoperative Complications and Retear Rate
Zeitfenster: Up to 12 months postoperatively
|
