: Recording of Vibroarthrographic (VAG) signals, emitted during movement of knee joint is a noninvasive technique for diagnosis of cartilage disorders. In this research a total of 22 features from frequency, time and time-frequency and six autoregressive model coefficients have been extracted from VAG signal. These features were classified by a feedforward neural network to two normal and abnormal groups. For our first data set the classification accuracy was 87.5% and for the second dataset it was 75%.
