Arthroscopic repair of a chondrolabral lesion associated with anterior glenohumeral dislocation.
Chondrolabral lesions are uncommon after anteroinferior glenohumeral dislocations. This report describes a new dual-lesion complex that involved an avulsion of the anteroinferior glenoid labrum and a flap tear of the adjacent articular cartilage [glenoid labral tear and articular cartilage flap (GLAF) lesion]. The chondral component involved a large undermined region of the anterior half of the lower glenoid articular cartilage, and the labral component involved an avulsion from the 2.30-6 o'clock position on the glenoid. The labral tear was reconstructed with 3 suture anchors to form a neo-labrum in an attempt to overlap and stabilize the periphery of the chondral flap. A meniscal repair device was used to place a mattress stitch in the cartilage periphery to further stabilize the flap. This technique resulted in a secure repair without any chondral damage, and this remained intact on an MRI performed at a 3-month follow-up. A final 12-month follow-up showed complete recovery, as assessed by the Oxford shoulder instability score and Rowe score, and by a return to the pre-injury sporting level.
