Knee Anthropometry Using Magnetic Resonance Imaging and Its Suitability with Three Implant Brands in Semen Padang Hospital Indonesia

Abstract

Knee implant is used in grade IV osteoarthritis for replacing the function of damaged joint. The precise measurement is highly needed. The smaller built and stature of the Indonesian population gives rise to geometric mismatch. It may need special size of implants. This research is a descriptive study of patients who underwent MRI examination without fractures, tumours or infections at distal femur and proximal tibia. The femoral and tibial components are measured. We compare it with three implant brands; Johnson&Johnson ® , Smith&Nephew ® and Gemini SL LINK ®. From the study, we get the results that the femoral components of three implants are suitable for being used, yet tibial components are not. Thus, it leads to overhang or underhang for Indonesia population which can cause impingement.
