No Major Functional Benefit After Bicompartmental Knee Arthroplasty Compared to Total Knee Arthroplasty at 5-Year Follow-Up

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 patients diagnosed with isolated medial and patellofemoral osteoarthritis were randomized to undergo a bi-compartmental knee arthroplasty (BCA; n=40) or total knee arthroplasty (TKA; n=40). Outcomes of interest included surgical time, blood loss, Oxford Knee Score (OKS), the Knee Society Score (KSS), range of motion (ROM), and the University of California, Los Angeles (UCLA) activity score which were all measured at baseline, 3 months, 6 months, 1 year, 2 year and 5 year post-operation. Furthermore, the Forgotten Joint Score (FJS), and the Timed-Up-and-Go Test (TUGT) were also evaluated at 5 year follow-up only. The results revealed that the OKS, KSS, UCLA activity score, TUGT, and FJS results were not statistically significantly different at any of the follow-up periods between the BKA and TKA groups (p>0.05 for all). However, the range of motion scores were statistically significantly greater in the BCA group at 6 months (p=0.02), 1 years (p=0.0016), and 2 years (p=0.001), and 5 years (p=0.003) post-operation. No cases of dislocation, fractures, or radiolucency were observed in either group.
