Background: Studies have shown that there are striking variations in knee morphology between Asian and Western population. However, most of the existing total knee arthroplasty (TKA) implants are designed to suit the anatomy of Western population. Our study investigated anthropometry of Indian arthritic knees and compared them to international ethnic groups. Methods: Computed tomography was used to create 3D knee models and obtain anthropometric data of distal femur and proximal tibia of Indian arthritic knees. Femoral measurements included mediolateral length, medial and lateral anteroposterior length, medial and lateral condylar width and aspect ratio. Tibial measurements included mediolateral length, medial, lateral and central anteroposterior length and aspect ratio. A preoperative virtual implantation using Western TKA implants was carried out to visualize anatomical conformity. Results: Statistical analysis results showed that Indian males had significantly larger femoral and tibial mediolateral and anteroposterior width than Indian females; however, femoral and tibial aspect ratio was similar for both. In case of females, significant difference was observed between medial and lateral condylar widths. When compared to knee anthropometry of other ethnic groups, femoral and tibial aspect ratio of Indian knees was found to be similar to the Asian population and different from the Western population. The virtual implantation showed overhang of the femoral component in both lateral and medial regions. Conclusion: Morphological mismatch between Western and Indian knees established the fact that Western implants have drawbacks when implanted in Indian patients. The study also provided a basis for designing gender-specific TKA implants for the Indian population.

Introduction: Most of the implants used for total knee arthroplasty in Asian patients have been produced based on anthropometry of Western people. Anthropometric studies have shown that there are significant variations in knee morphology between the Asian and Western population. Data of Indian knee morphometry of healthy and non osteoarthritic knee was lacking. Objective of this study was to study the knee anthropometry of Indian population and its comparison with other ethnic groups and current TKA Implants. Materials and Methods: 60 patients, 29 female and 31 male with peri-articlar knee injuries from the period of June 2016 to November 2016 were studied. 3D reconstruction of normal knee of the patients undergoing CT scan for injured knee was done. Measurement of the mediolateral width, anteroposterior width and aspect ratio of distal femur and proximal tibia was done. Data was compared with other ethnic groups and currently available and commonly used knee systems. Results: Indian females were found to have significantly (p>0.01) smaller dimensions of femur and tibia than Indian males and both had smaller aspect ratios than the Western population. Also study suggests that there is a morphological mismatch between commonly used implants and Indian knees. Conclusion: Our study suggests that why Western implant mismatches when implanted in Indian patients. Also this study provides definite rationale for designing total knee prosthesis, especially a gender-specific design suitable for the Indian population.
