The final step of reconstruction ligament fixation is the proximal tibial attachment of the sMCL. This soft-tissue attachment can be reproduced with a suture anchor [28] placed 12.2 mm distal to the medial joint line (average location), directly medial to the anterior arm of the semimembranosus tibial attachment.

The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm.
