Rotator Cuff Reconstruction With Xenologous Dermis-patch Augmentation and ACP® - Injection

• Oxford Shoulder Score (Questionnaire) [ Time Frame: 3mo ] [ Designated as safety issue: No ]
  The Oxford Shoulder Score used after 3 months is the primary parameter. The Score tests the ability to participate in the patients' normal life before they got injured.
  
  

• VAS Pain Scoring Tool [ Time Frame: 10d ] [ Designated as safety issue: No ]
  Measuring of the pain with a VAS pain scale during 10 days post-operative
  
  
• QuickDASH Questionnaire (Short version of Disability of the Arm, Shoulder and Hand Questionnaire) [ Time Frame: 3/6/24mo ] [ Designated as safety issue: No ]

  The Disabilities of the Arm, Shoulder and Hand (DASH) Outcome Measure is a 30-item, self-report questionnaire designed to measure physical function and symptoms in patients with any or several musculoskeletal disorders of the upper limb.

  The QuickDASH is a shortened version of the DASH Outcome Measure. Instead of 30 items, the QuickDASH uses 11 items to measure physical function and symptoms in people with any or multiple musculoskeletal disorders of the upper limb.

  
  
• EQ-5D Questionnaire [ Time Frame: 3/6/24 mo ] [ Designated as safety issue: No ]
  EQ-5D is a standardised measure of health status developed by the EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal.Applicable to a wide range of health conditions and treatments, it provides a simple descriptive profile and a single index value for health status that can be used in the clinical and economic evaluation of health care as well as in population health surveys.
  
  
• ROM (degrees) [ Time Frame: 3/6/24mo ] [ Designated as safety issue: No ]
  Range of motion refers to the distance and direction a joint can move.
  
  
• Measurement of the abduction strength (Kilograms) [ Time Frame: 3/6/24 mo ] [ Designated as safety issue: No ]
  
• ASES Score (American Shoulder And Elbow Surgeons Questionnaire) [ Time Frame: 3/6/24mo ] [ Designated as safety issue: No ]
  The ASES was developed to measure functional limitations and shoulder pain in people with musculoskeletal pathologies. Pain score was calculated from a single pain question on a visual analog scale (pain symptoms) and a function score from the sum of 10 questions addressing function using a 4-point ordinal scale (physical function). Pain and function are weighted equally and the total score ranges from 0 to 100 points, where 0 = worst and 100 = best.
  
  
• Constant Murley Score (CMS) [ Time Frame: 3/6/24 mo ] [ Designated as safety issue: No ]
  The CMS is a 100-point scoring system that is divided into four subscales: pain (15 points), activities of daily living (20 points), range of motion (40 points) and strength (25 points).Pain and activities of daily living are self-reported by the patient using visual analog scales and ordinal categories. Range of motion is obtained during active painfree elevation in flexion and abduction (using a goniometer), and functional internal and external rotation of the shoulder (using ordinal scale). Strength testing was performed at 90° of abduction in the scapular plane.
  
  
• MRI/X-Ray/Ultrasonic Diagnostics (Objective Evaluation (Descriptive) of the healing process) [ Time Frame: 6/24 mo ] [ Designated as safety issue: No ]
  
• Measurement of the external rotation strength (Kilograms) [ Time Frame: 3/6/24 mo ] [ Designated as safety issue: No ]
  
• Oxford Shoulder Score (Questionnaire) [ Time Frame: 6mo/24mo ] [ Designated as safety issue: No ]
  The Oxford Shoulder Score used after 3 months is the primary parameter. The Score tests the ability to participate in the patients' normal life before they got injured.
  
  

The shoulder joint, specially the rotator cuff, is one of the most complicated joints of the human body. If the tendon has to be fixed at the bone during surgery, the weak point in obtaining a successful surgery is the fixation of the tendon at the bone insertion site. Tendon belongs to the bradytrophic tissue conditional on the reduced blood flow, deep mitosis rate and lowered healing potential.

The patients in this study have 60 years or more. The tissue of these patients isn't as good as in young patients. The patch will be used to improve the strength of the tendon at the insertion site and the ingrowth process of the new tissue at this area. Additionally the investigators can boost the healing process with a selective use of PRP (PRP = platelet rich plasma). In this process, the healing site is delivered with an elevated concentration of thrombocytes and also growth factors which are constituent parts of them.
