Table 2 Comparison of the static and dynamic postural stability and the knee muscle strength in both knees between ACL rupture combined with MM tear and combined with LM tear groups

From: Poorer dynamic postural stability in patients with anterior cruciate ligament rupture combined with lateral meniscus tear than in those with medial meniscus tear
