Arthroscopic Xenograft With Cerclage Fixation: A Method for Glenoid Bone Loss Reconstruction With Cerclage Fixation...

Large glenoid bone defects are closely associated with high failure rates after arthroscopic Bankart repair in chronic anterior shoulder instability; therefore nowadays the glenoid bone grafting reconstruction procedure is strictly recommended. On the contrary, the optimal grafting procedure is still controversial because there is considerable concern about the resorption rate of allografts, donor site morbidity of the autografts, and sequelae caused by the use of metal fixation devices in proximity of the shoulder joint. We describe an all-arthroscopic technique for anatomic reconstruction of the glenoid that uses a previously shaped xenograft assembled with a metal-free fixation device using 2 ultra-high-strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL), using a specific posterior guide (Arthrex, Naples, FL) in combination with upper third subscapularis augmentation.
