Relationship Between the Arthroscopic Anatomy of the Middle Glenohumeral Ligament and the Rotator Cuff Tear Position

• Conditions: Rotator Cuff Tears
• Interventions: Procedure: Rotator cuff repair

• Registration Number: NCT05484271
• Lead Sponsor: RenJi Hospital

Brief Summary

The main aim and scope of this study is making observation and comparing the difference in the tear position in the patients suffered form rotator cuff tear with different arthroscopic anatomy of the middle glenohumeral ligament. The results may identify the influence of the middle glenohumeral ligament anatomy type on the rotator cuff tear.

Arm && Interventions

Group	Intervention	Description
Leaf-like and Cord-like type	Rotator cuff repair	Under arthroscopy, the anatomy of middle glenohumeral ligament was leaf-like or cord-like.
Burford complex type	Rotator cuff repair	Under arthroscopy, the anatomy of middle glenohumeral ligament manifested the burford complex.
Absent type	Rotator cuff repair	Under arthroscopy, the anatomy of middle glenohumeral ligament was absent.

Primary Outcome Measures

Name	Time	Method
The arthroscopic tear position (Anetrior/Middle/Posterior)	During the surgery	The rotator cuff was divided into three parts according to the arthroscopic discovery: (1) the anterior part which contained the subsacpularis and one third of the suprascapularis forward; (2) the middle part which contained the two thirds of the suprascapularis backward and one third of the subscapularis forward; (3) the posterior part which contained two thirds of subscapularis backward and teres minor.
