4. Torn Cartilage
On the other hand, discomfort might be being caused by a meniscus tear – or ‘torn cartilage’ as it is generally known. This requires quite ‘opposite’ exercises to repair, for instance, passive knee extensions where you will lie down flat again but this time place the towel under the heal and let gravity gradually straighten your knee for you.
Once again, this is best done with the guidance of a professional who can help you to address the issue.
