عنوان انگلیسی Correlation of Anthropometric Measurements of Proximal Tibia in Iranian Knees with Size of Current Tibial Implants
چکیده انگلیسی مقاله Background and objectives: Clinical studies have reported that Asian knee anatomical aspects are smaller than the Caucasian population. The purpose of this study was to investigate morphometry of proximal tibia in standard resected surface of total knee arthroplasty. Materials and methods: In this descriptive research in 2015, anthropometric data of proximal tibia were measured in 132 knees (80 males and 52 females) using magnetic resonance imaging (MRI). Data included anteroposterior (AP) length, mediolateral (ML) width, medial AP (MAP), lateral AP (LAP) and aspect ratio (ML/AP). The medial and lateral AP distance to bone center was calculated for symmetry analysis. The morphometric data were also compared with the same dimensions of four current tibial implants. Results: The mean age of subjects was 38.26 ± 11.45 year (20-60 years). The mean AP length and the mean ML width in the resected surface of bone as well as the mean aspect ratio (ML/AP) of tibial bone in all subjects were respectively 46.53±4.05 mm, 73.36±6.86 mm and 1.58±0.11 mm. The medial and lateral AP distance up to bone center were respectively 13.40±6.17 mm and 17.09±6.83 mm, indicating asymmetric proximal tibia in the study population. Conclusion: Measurements of anatomic shapes and dimensions of proximal tibial revealed that women have smaller dimensions than their male counterparts. Prostheses with smaller AP size tended to be undersized and larger AP size had tendency towards overhang in the mediolateral dimension. Data and the results of this study can be used as a guide to design tibial implant components suitable for total knee arthroplasty in Iranian population.
