31.14, 31.15 and 31.16 Thrust to medial meniscus supine This series of photographs shows the sequence of moves normally used in this technique. Flex and externally rotate the knee to break fixation in the medial meniscus. Gently repeat this a few times until nearly full flexion is attained. Maintaining the external rotation and some abduction of the knee, extend it until the position shown in photograph 15. At this point the final part of the technique takes over which is an extension, traction and internal rotation movement. At the end of the technique it is important to hold the knee firmly into extension, to avoid reflex muscle contraction into flexion that may dislodge the meniscus again.
Tips: Least useful where there is a suspected tear in the meniscus and the extension movement would be very painful. Extra considerations: It may take several attempts to produce sufficient flexion to unlock the joint. It may be very uncomfortable at the position shown in photograph 31.15 where the patient loses active control of the joint. It is important to pass through this point fairly quickly.
