Postoperative Corticosteroid Injection After Arthroscopic Rotator Cuff Repair in Patients With Stiffness Has Similar Clinical Outcome Compared With Repair Combined With Capsular Release: A Prospective Randomized Clinical Trial.

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

Eighty two patients with small–medium full-thickness supraspinatus tears and concomitant shoulder stiffness were randomized to arthroscopic rotator cuff repair (ARCR) with capsular release (n=41) or ARCR without capsular release plus a single intra-articular triamcinolone (40 mg in 1 mL) injection at 2 months post-op (n=41). The primary outcome was American Shoulder and Elbow Surgeons (ASES). Secondary outcomes included VAS pain, Constant score, Korean Shoulder Scale, ROM (forward flexion, external rotations, internal rotation), and structural integrity (MRI at 12 months). Outcomes were assessed pre-op; at 3, 6, and 12 months; and at last follow-up (mean 26.5 months). Overall, the results revealed significantly improved pain, function, and ROM from baseline in both groups, with no between-group differences at any time point except lower 3-month pain in the injection group. Retear rates were similar between groups. These findings suggest a single 2-month postoperative corticosteroid injection can substitute for intra-operative capsular release in this population.
