Video Playback Issues: If videos don’t play, it could be because you’ve remained on this web page for too long or you’ve lost your Internet connection. To resolve this issue, simply “refresh” or “reload” this web page.
No Sound? If you’re playing a video and the sound isn’t working, it may be because the sound is off. When playing a video from a desktop computer, you will see a series of vertical bars at the bottom right corner of the video. When the vertical bars are blue, it means the sound is on (see image 1 below). If the vertical bars are grey, it means the sound is off (see image 2). To turn on the sound of a video, click on each vertical grey bar until all the bars become blue. On smaller devices such as a tablet or a phone, simply increase the volume of the device to be able to hear a video.

This video will present a modified version of the McMurray’s test. McMurray’s test is used to detect the presence of medial and lateral meniscal tears.
This test is performed in two parts:
Part 1- Medial Meniscus:
To test the medial meniscus, with the patient in the supine position, grip the foot with one hand while the other is placed on the knee with the thumb over the lateral joint line and the index finger over the medial joint line. Now bring the knee to full flexion, then externally rotate the tibia by using the foot as a lever. While maintaining the external rotation, extend the knee.
This test is positive if a click is felt over the medial side of the joint as the knee is extended. The click is often accompanied by pain. This is indicative of a medial meniscal tear.
Part 2 – Lateral Meniscus:
To test the lateral meniscus repeat the procedure but this time internally rotate the tibia and then extend the knee while maintaining the internal rotation.
This test is positive if a click is felt over the lateral side of the joint as the knee is extended. The click is often accompanied by pain. This is indicative of a lateral meniscal tear.
It should be noted that McMurray’s test is described with a number of variations including the addition of valgus and varus loading.
