The Contribution of Platelet-Rich Plasma to the Surgical Treatment of Rotator Cuff Tear: An Experimental Study
Sponsor: KAT General Hospital
Summary
Purpose of the study: The aim of the study is to determine whether the postoperative administration of biological therapy with autologous platelet-rich plasma improves the clinical, imaging, and biochemical outcomes following surgical repair of a shoulder rotator cuff tear. What does the study involve? The study involves the postoperative administration of biological therapy after blood is drawn from the patients and processed appropriately. All patients will also undergo the necessary laboratory and imaging preoperative assessments, the surgical procedure, and standard postoperative rehabilitation, as routinely performed at this center. Tissue samples may be collected intraoperatively for testing. Postoperative follow-up will include clinical evaluations at specific time points-before surgery and at 1 month (regarding pain), 3 months, 6 months, and 1 year after therapy administration. At 6 months post-treatment, patients will undergo a follow-up MRI scan.

Interventions
Arthroscopic repair of shoulder rotator cuff tear
All patients received general anesthesia and were operated on in the "beach chair" position. Concerning the arthroscopic rotator cuff repair, systematic glenohumeral joint and subacromial exploration were performed, and lesions were managed as necessary. In each case, after the frayed and atrophied torn end was removed, the rotator cuff tear was carefully evaluated, and anteroposterior size, mediolateral retraction, number of involved tendons, visual tendon grade, excursion, and presence of the subscapularis tear were assessed. Debridement of bursal tissue and subacromial and distal clavicle osteophytes was minimally performed. Extensive acromioplasty to flatten a hooked or curved acromion was rarely performed. Rotator cuff repair was performed to cover the original footprint using suture anchors that were inserted through the accessory portal. The patients of both groups followed the same postoperative rehabilitation protocol.
PRP injection
The patients of treatment goup were administered a single intraarticular PRP injection in the operated shoulder at 10-15 days postoperatively. An autologous sample of 9 ml of peripheral blood was collected, and after addition of anticoagulant and preparation with a centrifuge for 6 minutes, 4ml of PRP was received and injected intraarticularly in a subacromial fashion.
