Abstract :
The authors have conducted studies on the recording and analysis of knee joint sound and angle signals using a microcomputer system. Short-time Fourier analysis techniques were used to study trends in the frequency content of the signals. Signals obtained from 16 patients before arthroscopy were analyzed. Signals corresponding to various degrees of chondromalacia and meniscal lesions demonstrated distinct characteristics, which should aid in automated analysis and diagnosis.<>
