Comparable Mid- to Long-term Outcomes of Semitendinosus and Semitendinosus/Gracilis Grafts in ACL Reconstruction: Median 8-Year (Range, 5-10 Years) Results From a Randomized Controlled Study.

この研究はインパクトが大きい可能性があると判断されました。 OEのAIによるハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文の影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することができ、読者は将来の診療を形成する可能性が最も高い論文に焦点を当てることができます。

研究概要

Ninety-eight patients with for anterior cruciate ligament (ACL) rupture were randomized to receive a quadrupled semitendinosus (ST-only) graft (n=49) or a doubled semitendinosus–gracilis (ST/G) graft (n=49); one ST-only patient was converted intra-op and excluded. The primary outcome was IKDC-Subjective score. Secondary outcomes included KOOS subscales, Tegner Activity Score (TAS), KT-1000 side-to-side laxity, Lachman and pivot-shift grades, sports/activity participation, and need for secondary surgery (including revision). Outcomes were assessed pre-op, 2 years, and again at a median of 8 years (range 5–10). Overall, the results of the study revealed no between-group differences at long-term follow-up for IKDC (ST 81.7 vs ST/G 82.1; p=0.93), instrumented or clinical stability, KOOS subscales, or revision rates; however, cyclops removal was more frequent with ST/G (p=0.014). Both groups showed large, durable improvements from baseline. These findings suggest ST-only grafts with adjustable-loop fixation perform comparably to traditional ST/G constructs at 5–10 years.
