Abstract

Arthroscopic posterior labral repair is an effective surgical technique for managing patients with posterior labral tears and symptomatic unidirectional posterior shoulder instability. It is well documented that a curved liberator from the mid-glenoid (anterior-inferior) portal passed from anterior to posterior provides an effective trajectory for liberation and mobilization of the posterior and posterior-inferior labral tear. However, biologic preparation of the posterior and inferior glenoid rim with a shaver can be challenging because the anterior mid-glenoid portal and the posterior portal do not provide an adequate trajectory for instruments to be parallel to the posterior glenoid rim. The purpose of this technical note is to describe a simple efficient procedure for biologic preparation of the posterior and inferior glenoid rim in the setting of arthroscopic posterior labral repair.
