Brief 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.

Detailed 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.

Interventions

OTHERdata 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.

Inclusion criteria

* Patient after an arthroscopic rotator cuff repair * 1 to 4 years postoperative * Presence of pre-operative radiography of the shoulder

Design outcomes

Primary

Measure	Time frame	Description
Change in Constant Score	1 year (before surgery and 1 year after surgery)	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).
