About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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
Absence of pre-operative radiography in neutral rotation

Treatment and study plan

Data analysis

Other

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.

Primary outcomes

Change in Constant Score

Time frame: 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).
