Clinical Trial Summary

This retrospective study is to investigate the influence of the Greater Tuberosity Angle (GTA) in addition to CSA on patient outcome in patients with rotator cuff tear.

Description:

A tear of the rotator cuff is one of the most common disorders of the shoulder. It is assumed that a large Critical Shoulder Angle (CSA) is associated with the occurrence of rotator cuff tears. This retrospective study is to investigate the influence of the Greater Tuberosity Angle (GTA) in addition to CSA on patient outcome in patients with rotator cuff tear.

Eligibility

Inclusion Criteria:

• Patient after an arthroscopic rotator cuff repair

• 1 to 4 years postoperative

• Presence of pre-operative radiography of the shoulder

Exclusion Criteria:

• Massive irreparable cuff tear

• Chronically retracted tendons and atrophic rotator cuff muscles Partial arthroscopic repair

Intervention

Other:
• data analysis
Data is extracted from the existing medical records and from the Rotator Cuff Repair Database (RCR_USB). The GTA (determined as the angle between a "line parallel to the humerus diaphysis passing through the humeral head center of rotation and a line connecting the upper border of the humeral head to the most superolateral edge of the greater tuberosity") is determined.

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Constant Score	This scoring system consists of four variables that are used to assess the function of the shoulder. The right and left shoulders are assessed separately.; The subjective variables are pain and activity of daily life (ADL) (sleep, work, recreation / sport) which give a total of 35 points. The objective variables are range of motion and strength which give a total of 65 Points (the higher the score the better the shoulder function).	1 year (before surgery and 1 year after surgery)
