Abstract

The purpose of this study was to report the demographics and clinical outcomes of patients at our institution following anterior cruciate ligament reconstruction (ACLR) with a planned or unplanned hybrid autograft–allograft. At a minimum 2-year follow-up, patients at our institution who had undergone primary ACLR with a planned (P) or unplanned (U) hybrid graft using fresh-frozen allografts were contacted to complete a survey containing the Knee Injury and Osteoarthritis Outcome Score, Subjective International Knee Documentation Committee score, Single Assessment Numeric Evaluation, 12-Item Short Form Health Survey, and visual analog scale for activity level. Demographics were compared between groups. Patient-reported outcomes (PROs) and a revision rate were reported for each group. Mean follow-up among all patients was 3.3 years. Revision rate at follow-up was 0.8 and 6.3% in the P and U groups, respectively (p = 0.03). Among patients reached for follow-up (90 P, 30 U), a lower proportion of males was found in the unplanned hybrid graft group (P: 52%, U: 23%, p < 0.01). Unplanned hybrid graft patients were significantly younger at the time of surgery (P: 41.0 years, U: 31.0 years, p < 0.0001). Graft size did not differ between groups (P: 9.1 mm, U: 8.9 mm, p = 0.11). Patients in both groups achieved moderate to high PROs. Demographics differ between patients undergoing ACLR with a planned or unplanned hybrid graft. Patients with a planned hybrid graft are at a significantly reduced risk of postoperative graft failure, likely due to the older age of this group.
