“…Our study shows that significant differences exist between the knees of different races (Tables 5 and 6). 3,6,7,16,18) The Indian knees resembled the Chinese knees, but were smaller than the Caucasian and Hispanic knees. This racial difference explains the implant size mismatch seen in our study.…”

Anthropometry of Nonarthritic Asian Knees: Is It Time for a Race-Specific Knee Implant?

The morphology of the knee joint has been proven to vary considerably amongst the various ethnic groups, genders, and morphotype of the patients. Having a normative data for a particular population subset is important as it helps to design the knee joint prosthesis that will have the best fit and size for the knees. 1) Suboptimal sizing and placement leads to various issues like patellar maltracking, persistent pain, early loosening, loss of bone stock, and increase in propensity of periprosthetic fractures. 2) Literature review revealed a striking paucity of information on anthropometric measurements of Asian knees. Most of the anthropometric data currently available for Indian knees are derived from measurements made on osteoarthritic knees. 3,4) Heidari 5) showed that the presence of osteophytes, subchondral sclerosis, bone attrition, and

“…To establish the racial difference in knee anthropometry, we compared the results of our study with those of similar studies done on healthy knees in different populations. We used the data from studies by Li et al 6) for Caucasian and Chinese populations and data from Mcnamara et al 7) for the Hispanic population.…”

“…Whereas gender differences in coronal alignment parameters have been described extensively, ethnical differences remain rather unclear [4,5]. The few existing studies were mainly focused on anthropometric parameters such as medial-lateral and/ or anterior-posterior ratios and showed significant ethnical differences [6][7][8]. Consequently, ethnical differences in coronal alignment parameters would seem natural.…”

The purpose of this study was to determine the distribution of functional knee phenotypes in a non-osteoarthritic Asian population. The Stryker Orthopaedic Modeling and Analytics (SOMA) database was searched for CT scans of the lower limb meeting the following inclusion criteria: patient age at time of image >18 and <46 years, no signs of fractures and/or previous surgery and/or degenerative changes, Asian ethnicity. A total of 80 CT scans of 40 patients were included (24 males, 16 females). The hip-knee-ankle angle (HKA), femoral mechanical angle (FMA) and tibial mechanical angle (TMA) were measured. Based on these measurements, each limb was phenotyped according to the previously introduced functional knee phenotype concept. All angles and phenotypes of the present study were compared with previously published data of a non-osteoarthritic Caucasian population (308 legs of 160 patients, 102 males, 58 females). Asian knees had a significantly lower TMA (both genders p < 0.001) but a higher FMA (males p < 0.05, females p < 0.001) than Caucasian knees but showed no difference in the HKA. Asian knees differed significantly with regard to femoral and tibial phenotypes (p < 0.01), but not with regard to limb phenotypes. The high variability of all coronal alignment parameters highlights the importance of a detailed analysis prior to TKA. Ethnical differences underline the need for a more individualized approach in TKA.

“…To get accurate anthropometric data, the measurements should be performed on a normal knee model (either radiographic, CT, or MRI), as the arthritis process alters the anatomic dimensions (24). In the current study, we used MRI scans to obtain the desired measurements; this technique was used by most previous studies reporting anthropometric knee evaluation (18)(19)(20)22), as the values measured by MRI were reported to equal those measured intraoperatively by direct methods (27). Moreover, MRI accounts for cartilage thickness, which corresponds to sizing techniques in most TKA systems (18).…”

Background: Knee anthropometric characteristics were evaluated for different ethnicities; however, data from North African populations are deficient. The primary aim was to investigate the Egyptian knees' anthropometric characteristics as a representative of North African populations. Secondary aims: 1) to study the anthropometric gender difference, 2) to compare results with other ethnic groups, and 3) to study the mismatch in comparison to geometric characteristics of modern TKA implant designs. Methods: 200 normal knee MRI scans (100 females and 100 males, aging from 18 to 60) were obtained for analysis. Linear measurements (Anteroposterior (AP), Mediolateral (ML), and Aspect ratio (AR)) of the planned cut surface of the distal femur (f) and the proximal tibia (t) were evaluated. Results: A significant difference between both sexes was found, males had larger measurements in anteroposterior [fAP: 60.97 ± 3.1 vs 54.78 ± 3.3 (P < 0.001), tAP: 46.89 ± 3.0 vs 41.35 ± 2.9 (P < 0.001)] and mediolateral [fML: 74.89 ± 3.2 vs 67.29 ± 3.7 (P < 0.001), tML: 76.01 ± 3.0 vs 67.26 ± 3.2 (P < 0.001)], the mean femoral and tibial AP and ML measurements were different from other ethnic groups. None of the seven studied TKA systems matched the largest ML or the smallest AP dimensions of the distal femur in the current study population. Conclusion: A significant difference was found between males' and females' knee anthropometric characteristics. Some of the commonly used TKA implants in our area could not provide a perfect fit and coverage.Trial registration: Clinical Trials .gov identifier: NCT03622034, registered July 28, 2018, (https://clinicaltrials.gov/ct2/show/record/NCT03622034).
