Objectives: Implant replacement in knee is a major operation in which the joint is replaced by metallic implants. Methods: When changing the liner of knee implant, surgeon must know the type of implant used prior to the surgery. Findings: A new approach to identify the implant used in knee replacement operation using digital image processing techniques was proposed and implemented. The X-ray image was preprocessed and an image database of various implants with their specification was prepared. For testing the X-ray image was acquired and pre processed. After using various images processing operations on the X-ray image, the implant used in patient body was identified by the new approach template matching.
