The type of rehab exercise for a lateral meniscus injury depends on the severity of the injury, the age of the individual and his or her ability to recuperate from physical afflictions. The goal of rehabilitation exercises is to restore the joint's health by building strength and endurance though a series of smoothly executed, repetitive motions centered on the knee. Sometimes, lateral meniscus injuries require surgery before rehabilitation exercises are beneficial to injured knees.
Lateral Meniscus
Sometimes referred to as external semilunar fibrocartilage, the lateral meniscus is a fibrous band of tough tissue that extends over the lateral side of the knee joint. The other meniscus is the medial meniscus, which covers a larger area of the knee. Both might be sprained when the knee is twisted or experiences continuously-applied force, such as sports that require running and abrupt maneuvering. Basically, the meniscus reacts like a shock absorber, alleviating wear and tear on the joint much like what a shock absorber does for the undercarriage of a car.
Heel Slide
Range of motion exercises for an injured meniscus may include knee extensions and heels slides. To perform heels slides, lie on your back on the floor or bed and wrap a towel around your ankle. Keep your heel on the floor and slide your heel toward your buttock. Hold this position for up to 10 seconds and then return it to the starting position. You may pull lightly on the towel to help, as long as it does not cause pain. Do 10 to 15 repetitions, three times a day.
Leg Curls
The leg curl exercise, which also strengthens hamstring muscles, should be implemented once swelling subsides. Make sure it is safe to use weights before you attempt this exercise. Attach a lightweight ankle weight to your ankle and lie on the floor on your stomach with your legs out straight. Slowly lift your foot and bend your knee until your heel almost touches your buttock. Pause for a second and then return to the starting position to complete one rep. Do two sets of 15 to 20 repetitions, every other day. Don't force any movements and stop if you hear popping or cracking sounds. You may increase the weight used as your knee grows stronger.
Caution
Frequently, symptoms of exacerbation may not emerge until several hours or even a day later. For this reason, rehab exercises should be performed minimally in the beginning to allow the meniscus tear to heal and strengthen gradually. Speak to your doctor if symptoms suddenly get worse or don’t seem to improve.
