Evaluation of glenoid capsulolabral complex insertional anatomy and restoration with single- and double-row capsulolabral repairs.
BACKGROUND
The purpose of this study was to evaluate the normal glenoid insertional anatomy of the anterior-inferior capsulolabral complex and to compare the ability of a single-row repair and a double-row suture bridge repair to restore the insertional anatomy.


METHODS
Eight fresh frozen cadaver shoulders were dissected and the native glenoid insertion of the anterior-inferior capsulolabral complex was digitized. Bankart lesions were created, the shoulders were randomized to receive either the standard single-row suture anchor repair or a double-row suture bridge repair, and the insertion repair sites were then digitized.


RESULTS
The single-row repair recreated 42.3% of the native footprint surface area while the double-row repair recreated 85.9%. The double-row repair was significantly larger and recreated significantly more of the native footprint compared with single-row repair (P < .01).


CONCLUSIONS
Double-row repair of the capsulolabral complex reestablishes the native insertional footprint on the anterior inferior glenoid better than a single-row repair.


METHODS
Basic science study.
