Title: | Principal component analysis as a tool for determining optimal tibial baseplate geometry in modern TKA design | Authors: | Huijs, S. Huysmans, T. de Jong, A. Arnout, N. Sijbers, J. BELLEMANS, Johan |
Issue Date: | 2018 | Publisher: | ACTA MEDICA BELGICA | Source: | ACTA ORTHOPAEDICA BELGICA, 84(4), p. 452-460 | Abstract: | Optimal tibial component fixation in total knee arthroplasty (TKA) requires maximal tibial bone coverage, optimized mediolateral cortical tit as well as component rotation. Failure to achieve an optimal fit may result in component subsidence and loosening in case of undersizing, or overhang with subsequent soft tissue impingement in case of overhang. To date there is no consensus on optimal tibial component shape, and significant variability exists among different design manufacturers. In this study "principal component analysis" was used as a statistical tool in order to determine the ideal tibia baseplate shape, based upon anthropometric CT-scan data defining an average proximal tibial shape and variations. Gender specificity was evaluated and differences in geometry depending on anatomic constitution (yarns, neutral, valgus) were analyzed. The results from our study indicate that in the arthritic knee differences in proximal tibial morphology at the resection level were mainly attributed to size and not shape. This is true for both Caucasian men and women, and is independent from the anatomical constitution. | Notes: | [Huijs, S.; Huysmans, T.; de Jong, A.; Arnout, N.; Sijbers, J.; Bellemans, J.] Sint Augustinus Hosp, Antwerp, Belgium.
