| 要約: | Introduction: Knee joint problems, such as Osteoarthritis
(OA), primarily affect the upper weight-bearing end of the tibia.
Total and unicompartmental knee arthroplasty are commonly
performed as treatment options. However, existing studies
on morphometric assessment of the knee joint mainly focus
on the Western population, with a lack of data among the
Indian population. Obtaining such data is crucial for designing
tibial components of knee prostheses tailored to the Indian
population.
Aim: To compare the morphometric data of the upper end of
the tibia between the North and East Indian populations.
Materials and Methods: A cross-sectional observational study
was conducted in the Department of Anatomy at FMHS Medical
College, SGT University, Gurugram, Haryana, North India,
involving 41 dry tibias, and at Medical College and Hospital
Kolkata in East India, involving 43 dry tibias. Measurements of
the Anteroposterior (AP) and Transverse Diameters (TD) of the
Medial Tibial Condyle (MTC), Lateral Tibial Condyle (LTC), and
Total Tibial Condyles (TTC) were performed using digital Vernier
callipers with a least count of 0.01 mm. The data was statistically
analysed using Statistical Package for Social Sciences (SPSS)
(version 21.0), and Student’s t-test was applied, with p<0.05
considered significant.
Results: The mean TD and AP diameters of the tibial plateau
were found to be greater in the East Indian population (TD:
65.47±5.46, AP: 44.29±4.36). In both samples, the AP diameter
of MTC (North Indians: 38.30±3.54, East Indians: 40.63±3.46)
was greater than that of LTC (North samples: 35.30±3.51, East
samples: 35.70±3.96). When comparing parameters between
the North and East samples using Student’s t-test, significant
differences were found on the right-side for the mean AP
(p-value=0.0065) and TD (p-value=0.0213) of TTC, mean AP
(p-value=0.0006) and TD (p-value=0.0219) of MTC, mean TD
of LTC (p-value=0.0002), mean AP (p-value=0.0005) and TD
(p<0.0001) of the Intercondylar area at anterior ends, and mean
AP (p<0.0001) and TD (p-value=0.0017) of the Intercondylar area
at posterior ends. On the left-side, significant differences between
the North and East population were found for mean TD of LTC
(p-value=0.0348), AP (p<0.0001) and TD (p-value=0.0207) of
the Intercondylar area posterior end. When comparing the areas
between the North and East populations, significant differences
were found on the right-side only for the MTC (p-value=0.0013),
LTC (p-value=0.0083), and TTC (p-value=0.0055).
Conclusion: There are significant regional variations in the
anthropometric measurements of the North and East Indian
populations, emphasising the need to develop populationspecific tibial prostheses for improved surgical outcomes. |
