Radiostereometric analysis study of tantalum compared with titanium acetabular cups and highly cross-linked compared with conventional liners in young patients undergoing total hip replacement

この研究はハイインパクトの可能性があります。 OEのAI駆動型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、論文が持つ可能性の高い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可能になり、読者は将来の診療を形成する可能性が最も高い論文に集中することができます。

46 patients undergoing total hip arthroplasty were randomized to one of four groups: a highly-crosslinked polyethylene (HXLPE) liner in either a titanium or tantalum acetabular cup, or an ultra-high-molecular-weight polyethylene (UHMWPE) liner in either a titanium or tantalum acetabular cup. The purpose of this study was to determine whether liner material had a significant effect on femoral head penetration (liner wear), and whether acetabular cup material had a significant effect on acetabular component migration. Follow-up was performed for 5 year postoperatively. Results demonstrated significantly lower liner wear in HXLPE cohorts compared to UHMWPE cohorts, and no significant differences in acetabular cup migration between titanium and tantalum. No group was associated with significantly better or worse clinical outcome than any other group, as no statistically significant between group differences were noted for SF-36, WOMAC, UCLA, or HHS scores.
