Abstract
Objective: Total knee arthroplasty and unicompartmental knee arthroplasty (UKA) are frequently done procedures for the treatment of various forms of arthritis and knee injuries. The knee prosthesis, which is used for these procedures requires adequate sizing specific to the population. Hence, the aim of the present study is to measure various parameters of the proximal end of the tibia in south Indian population. Materials and Methods: Fifty (26 left and 24 right) adult fully ossified dry tibia were taken, and various parameters of the proximal end of the tibia were measured using a Vernier caliper. Statistical analysis of the parameters was done. Comparison between various parameters of right and left side was done using paired t-test. Results: In our study, the mean transverse, the anteroposterior diameter of total, medial and lateral condyles of the tibia are 6.83, 4.57, 2.73, 4.45 and 2.79, 4.07 cm. The area of medial, lateral and total tibial condyle is 12.2, 11.42 and 31.39 cm 2 . The mean length between the upper end of the tibia and tibial tuberosity and the mean circumference of the upper end of the tibia is 5.15 and 19.02 cm. Groove for ligamentum patellae was found in 100% of cases. Conclusion: The results of this study will be helpful for anatomists, anthropologists, and orthopedics in cases of UKA, complete knee arthroplasty procedures, and meniscal transplantation.
