Poster 352: Adverse Events and Complications following Primary ACL Reconstruction with Quadriceps Tendon Autograft: A Systematic Review

Objectives: To systematically review the incidence of postoperative complications and adverse events following primary ACLR with quadriceps tendon autograft, while secondarily comparing reported rates in an all-soft tissue (QT) graft relative to grafts a patellar bone plug (QTPB). Methods: Two independent authors conducted literature search using PubMed, Embase, Scopus databases Preferred Reporting Items for Systematic Meta-Analyses (PRISMA) guidelines. The strategy included keywords combined Boolean operators: ‘Anterior Cruciate Ligament’, ‘ACL’ ‘Reconstruction’, ‘Quadriceps Tendon’. Inclusion criteria consisted level I IV human clinical studies English or English-language translation reporting after autograft. overall throughout studies, as well specific were extracted. A 2- proportion z-test was performed evaluate potential differences between without plug. Results: total twenty consisting 2,381 patients (2,389 knees) mean age 27 (mean range, 12 - 58) years, 68.3% males (n=1626/2381), identified. follow-up 28.5 6 – 47) months. 10.3% (n = 246/2389 patients), persistent post-operative knee pain being most common, seen 10.8% 91/843) knees. Patients who underwent ACL reconstruction QT had increased (23.3%) reoperations (5.9%) when compared QTPB (8.6% 3.2%, respectively) (p < .01). Nontraumatic ruptures greater (2.1%) (0.5%) 0.01). There no appreciable difference complications, failures, traumatic rupture, revisions, cyclops lesions, arthrofibrosis (all, p > 0.05). Patellar fractures occurred exclusively (2.2%). Conclusions: Complications autograft recorded 10.5% knees, common which is pain. No use versus grafts, however 2.7x QT. [Table: see text][Table: text]
