PG - e156-e158 LID - 10.1097/JSM.0000000000000715 [doi] AB - The association between donor-specific human leukocyte antigen (HLA) antibody formation and small bone allograft resorption has not been studied. We present the case of a patient treated for glenoid bone loss using a distal tibial allograft with Bankart repair who formed donor-specific HLA antibodies against the allograft and had subsequent graft resorption. X-ray and computed tomography (CT) scans were performed before and after surgery at standard checkpoints. Patient blood and serum samples were collected before and after surgery for HLA typing and HLA antibody testing. Human leukocyte antigen antibodies against the donor-specific HLA-A2 antigens were identified 6 weeks after surgery and were still detected at 5 months after surgery. At 6 months after surgery, a CT arthrogram revealed significant graft resorption. This case shows a temporal correlation between HLA antibody formation and clinical findings, potentially suggesting an association between HLA antibody formation and graft resorption. Further study is required to confirm this.
