Total Knee Arthroplasty (TKA) involves the parameter of the distal femur size and proximal tibia size. An accurate of measurements can improve the physiology function of knee after implant and the tissue surrounding the knee. Most of the prosthesis size commercially is following Western measurement therefore the accuracy of having prosthesis for Asian is low compare to others. The probability of mismatch of prosthesis is high in Asian population. A good prosthesis shown the significant in pain relief, improved function and quality if life. However, the mismatch of prosthesis can cause some severe complication to patient and bring some negative impact to patient. Most of the arthroplasty knee is involved in the middle age group but nowadays
