Abstract
Objective: This study was aimed to determine anthropometric measurements of knee joint among healthy Mongolian population and identify FML (Femur Medial Lateral), TML (Tibia Media Lateral), PML (Patella Medial Lateral), PAP (Patella Anterior Posterior), FAP (Femur Anterior Posterior) and TAP (Tibia Anterior Posterior). Methods: This cross-sectional study included 100 participants. We measured femoral, tibial and patellar dimensions using X-ray. Result: A total of 100 participants (44 male, 56 female participants) enrolled in this study. Age was ranged 20 - 59 and average age was 38 ± 9. Average FAP was 70.6 ± 1.22 mm in male and 66.9 ± 3.93 mm in female. Average TML in male was 85.6 ± 1.27 mm and 79.1 ± 0.8 mm in female. Average TAP was 60.1 ± 4.87 mm in male and 55.7 ± 4.96 in female. Average PAP was 22.5 ± 2.83 mm in male and 23.8 ± 2.43 mm in female. Average PML was 50.2 ± 1.45 mm in male and 46.8 ± 4.09 mm in female. Knee anthropometric measurements were statistically different in gender (P Conclusion: Participants average FML was statistically lower than Asian and European people and FAP was statistically higher than them.
Highlights
In 1970, total knee joint arthroplasty guideline was created in USA
Manufacturing companies are trying to produce knee prosthesis for such nationalities based on their knee anthropometric measurements
Independent t-test used for examine difference between men and women knee joint anthropometric measurements when normal distribution
Summary
(OA) is increasing 10% - 15% year by year. Related to OA, burden of musculoskeletal disability is increasing as well [1]. Ligaments were kept and replace joint surface was developed. The result of this study showed that anthropometric references of Chinese knee were generally smaller than white knees [3]. Another study showed that knee anthropometric references of Chinese, Thailand and Japanese people are similar [4]. Tibial surface of white people was greater than black people. They emphasized that patient-specific designed prosthesis based on individual anatomical reference can reduce the surgical complication, enhance the functional recovery and quality of life [5]. Knee replacement surgery has been increasing as well as its demands.
