title: Measurement of knee joint motion using digital imaging.
abstract: The measurement of joint motion is common practice in many aspects of orthopaedic surgery. A number of techniques and instruments have been developed for this purpose. We describe a method of recording and measuring knee joint motion using digital imaging which demonstrated high inter-observer reliability (r > 0.948) and intra-observer repeatability (r > 0.906). This technique may offer some practical advantages over other methods of measuring joint motion.
