Anterior Cruciate Ligament Reconstructions with Quadriceps Tendon Autograft Result in Lower Graft Rupture Rates but Similar Patient-Reported Outcomes as Compared with Hamstring Tendon Autograft.
Armin Runer et al. Am J Sports Med. 2020; 48(9): 2195-2204.
This prospective cohort study performed in Innsbruck, Austria evaluates the outcomes of ACL reconstruction in 875 patients with 2 year follow up. Outcomes measured were rate of rupture of the ACL graft, visual naalog pain scale scores, Lysholm scores, and Tegner activity scores.
RESULTS: Odds of graft rupture were 2.7 times greater in patients treated with ACL reconstruction with hamstring autograft as compared to quadriceps tendon autograft. Other factors that increase risk of graft rupture were younger age and higher activity level. There were not differences in the other patient-reported outcomes.
Big Takeaway: Use of quadriceps tendon autograft for ACL reconstruction is favored over hamstring tendon autograft.
Other takeaway: Further research is needed comparing quadriceps tendon autograft to bone-patellar tendon-bone autograft for ACL reconstruction.
