Study Description
Brief Summary:
The objective of this study was to prospectively evaluate the influence of local application of Platelet Rich Fibrin (PRF) on the functional outcome and integrity of the arthroscopically repaired tendons in patients with massive tears of the rotator cuff.

Condition or disease Intervention/treatment Phase
Rotator Cuff Tears of the Shoulder Procedure: Arthroscopic repair without platelet rich fibrin Biological: PRF (vivostat ®) administration after rotator cuff repair Phase 2

Detailed Description:
A prospective, randomized clinical trial was performed on 28 patients (22 females, 6 males) with an average age of 65 years (range, 53 to 77) undergoing complete arthroscopic repair of a massive rotator cuff tear. In 14 patients, after the repair was completed, 6 cc. of PRF (vivostat ®) were locally applied to the repair site. In 14 patients no addition of PRF was performed. All patients underwent an arthro-MRI to evaluate the integrity of the repair and a clinical exam one year after the operation. All patients were then followed clinically at a minimum of 2 years. Functional outcome was evaluated with the Constant and DASH scores.

Arms and Interventions

Arm Intervention/treatment
Experimental: PRF
the group in which the PRF was administered
Biological: PRF (vivostat ®) administration after rotator cuff repair
7cc. of autologous PRF are locally administered to the repair site after reconstruction of the rotator cuff
Active Comparator: Control
repair without PRF
Procedure: Arthroscopic repair without platelet rich fibrin
after the tendon is repaired, no additional procedures are performed and no PRF is administered

Outcome Measures

Primary Outcome Measures :
  1. rotator cuff tear healing rate after surgical reconstruction evaluated by arthro-MRI [ Time Frame: one year ]

Secondary Outcome Measures :
  1. functional outcome evaluated with constant score [ Time Frame: two years ]
  2. disability outcome evaluated with dash score [ Time Frame: two years ]
