Morphometric Study of Superior Surface of Proximal End of Tibia

Abstract

Background: The knee joint is one of the largest joint of human body, it not only provides locomotion but also helps in weight bearing of the body. The knee joint is most often affected by osteoarthritis ,fractures or any other traumas. Therefore for the treatment of such conditions frequently adopted procedure are total knee arthroplasty and unicompartmental knee arthroplasty. For the success of such procedures the prosthesis and the resected bone surface should match irreproachably.The aim of the present study was to measure different condylar and intercondylardiametres of superior surface of tibia  as it provides the framework for designing prosthesis of accurate size.

Materials and method: The current study was conducted on 81 dry tibial bones in Department of Anatomy, National Institute of Medical Science and Research Jaipur Rajasthan. Various condylar and intercondylar diameter of superior surface of tibia were measured with the help of digital vernier caliper.

Result: In the present study, mediolateral and transverse diameter of medial condyle was found to be greater than the lateral condyle, the anteroposterior diameter was found to be more than that of transverse diameter. These all parameters on comparison with other studies shows that there is a great variation in morphometry of upper end of tibia according to different regions.

Conclusion:    The present study will provide morphometric data of superior surface of tibia which will be helpful for reshaping and resizing of prosthesis in total knee arthroplasty and unicompartmental knee arthroplasty and also of great use for orthopaedician.
