Morphometric Study of Medial and Lateral Condyle of the Tibia in North Indian Population

Abstract

SUMMARY: Total and unicompartmental joints replacements have become the main standard for the treatment of degenerative disorders and osteoarthritis of the knee. In total knee arthroplasty less than half an inch (9 mm) of the tibial and femoral articular surfaces are removed from the ends of bones and replace the metal and plastic prosthesis. There by the dimensions of each condyle are requisite for designing prosthesis required for knee arthroplasty. Fifty (25 right & 25 left) adult fully ossied dry tibias were taken from the Department of Anatomy and morphometric measurements of medial and lateral condyle were taken by using a Vernier caliper. Statistical analysis of the parameters was done. Present study, the mean anteroposterior, the transverse diameter of medial and lateral condyles of tibia were 45.71±3.17, 29.75±2.95, and 39.71±3.09, 30.24±2.45 mm respectively. The mean mediolateral length of total tibia and the mean circumference of the upper tibia were 69.35±5.08 and 191.49±14.85 mm respectively. The results of this study will be helpful for anatomists, anthropologists, and orthopedics in cases of unicompartmental knee arthroplasty, complete knee arthroplasty procedures, and meniscal transplantation.
