Comparing alignment, functional and survival outcomes in computer-navigated vs. conventional TKA .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
A Comparison of Long-Term Outcomes of Computer-Navigated and Conventional Total Knee Arthroplasty: A Meta-Analysis of Randomized Controlled Trials
J Bone Joint Surg Am. 2019 Oct 16;101(20):1875-1885.9 studies were included in this meta-analysis comparing computer-navigated and conventional TKA with regards to radiological, long-term function and survivorship outcomes. Outcomes of interest included the outlier rate of coronal and sagittal alignment of the femoral and tibial components, the outlier rate of lower extremity alignment, range of motion, the Knee Society Score (KSS), the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, revision rate and rate of aseptic loosening. Results found significantly lower outlier rates of sagittal alignment of the femoral component and coronal alignment of the tibial component in the computer-navigated TKA group compared to the conventional TKA group. No significant differences were observed between the two groups in all remaining outcomes.
