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

Abstract

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

Evaluation of patellar dimension and Bristol Index in Asian population: An MRI study

“…We found that male patella was significantly larger of all measurement of patella except patellar cartilage which is consistent with other literatures [ [11] , [13] , [14] , [15] ]. Hence, this will need a consideration during a patellar resurfacing or replacement.…”

“…The aim was to aid surgeons achieving the anatomic native patella size during patellar resurfacing or replacement in TKA. Several literatures ( Table 3 ) found female Asian patellae were significantly smaller compared to Caucasian's [ 1 , 12 , 13 ]. However, our finding showed similar dimension between Asian and Caucasian patellae.…”

Comparison of Anterior-Posterior Axis Versus Transepicondylar Axis in Patients Undergoing Simultaneous Bilateral Total Knee Arthroplasty: One Technique per Knee

“…Clinical comparison of axial rotational reference lines is difficult. First, each patient has unique knee anthropometry [10][11][12][13]. Secondly, each patient has a unique degenerative history creating their knee deformity.…”
