This paper proposes a software approach using MATLAB to measure the angular deformity as well as recognizing the type of deformity present. This can give a meaningful approach to measure the most accurate deformed angle due the Valgus and Varus knee deformity. The proposed software aids the orthopedic surgeons in knee surgeries, knee implantation and correcting the deformed knees. Thus it will revolutionize the knee surgeries and speed up the process, avoiding delay in treatment and a great relieve to the patient. Based on the deformed angle doctor can decide whether surgery is needed or not.
