Meniscus is a cartilage in the knee that acts as a shock absorber and also acts as a cushion to the knee. Each knee has two menisci — one on the inside and one on the outside of the knee. A tear to the meniscus can cause pain and swelling and can worsen with activities such as squatting or twisting. Walking does not help with meniscus problems, as walking does not help with toning or strengthening any of the leg muscles.
Treatment
Ice or cold therapy is the first recommended treatment for meniscus tear. Do not apply ice directly on the skin; wrap it with a piece of cloth. Pain medications such as anti-inflammatory drugs can reduce pain and swelling. Heat therapy can follow after the initial period of ice therapy to prevent stiffness. The meniscus may be supported by strengthening the muscles of the quadriceps and hamstrings.
Braces
Braces can be used to keep the knee stable and warm. They will also help in reducing pain and decrease movements such as turns and twists, which should be avoided with a meniscus tear. Braces will allow you to do necessary movements such as walking. Bracing will also stimulate some nerve fibers while giving the necessary compression.
Activities
Certain activities should be avoided because they can cause pain or further injury to the meniscus. Avoid squatting, lifting heavy objects, kneeling, climbing and running. Twisting the knee or sudden jerks to the knee can worsen the tear. Also avoid any activities that increase pain. Walking on an uneven terrain should be avoided, as it can easily cause you to twist the knee.
Rehabilitation
A number of rehabilitative exercises can increase flexibility and also strengthen the upper leg muscles. Walking does not help meniscus problems, but walking in a pool at a quick pace in chest-deep water can be helpful for meniscus tears. Another good exercise is to stand against the side of a pool, hold onto the wall and make small flutter kicks. Stationary bicycle rides and lightweight leg extensions can be helpful for meniscus problems.
