A torn meniscus is a common injury that occurs when the meniscus, a piece of cartilage in the knee joint, gets torn or damaged. This can happen due to sudden twisting or bending of the knee, or from wear and tear over time. Meniscus tears oftentimes result in pain, swelling, stiffness, and difficulty moving the knee.
While surgery may be necessary for severe or complex meniscus tears, many tears can be managed conservatively, with physical therapy and exercise. The goal of exercise is to strengthen the muscles around the knee, improve flexibility, and reduce pressure on the meniscus.
What is Meniscus Tear?
A meniscus is a piece of cartilage in the knee joint that acts as a shock absorber, aids in joint lubrication, and helps to distribute the weight of the body during movement. A torn meniscus occurs due to sudden twisting or bending of the knee or from gradual wear and tear over time. Meniscus tears are a common knee injury, especially among athletes, and can cause joint pain, swelling and stiffness, and issues moving the knee. Most of the time, treatment for a meniscus tear will involve nonsurgical measures such as rest, ice, compression, elevation (RICE), physical therapy, anti-inflammatory medications (i.e. ibuprofen, naproxen), steroid and biologic injections. Surgery may be needed for more severe tears.
What are the symptoms of Meniscus tears?
Symptoms of a torn meniscus often vary depending on the severity and location of the tear. Common symptoms include:
- Pain: Meniscus tears can cause pain in the affected knee.
- Swelling: The knee may become swollen and stiff, making it difficult to move.
- Stiffness: A meniscus tear can cause stiffness in the knee joint, making it difficult to bend or straighten the leg.
- Locking or catching: The torn meniscus can become caught in the knee joint, causing the knee to lock up or catch during movement.
- Popping or clicking: This sensation in the knee joint is usually the first symptom experienced as the tear occurs.
- Loss of range of motion: A tear can cause the inability to move your knee through full range of motion.
It’s important to note that these symptoms can also be associated with other knee injuries or conditions, so it’s important to see a doctor for a proper diagnosis if you experience any of these symptoms.
What are the different types of meniscus tears?
There are several types of meniscus tears, which are classified based on the location, pattern, and severity of the tear. The most common types of meniscus tears include:
- Radial tear: This is the most common type of tear. It occurs more often in the area of the knee without blood supply (avasculture) and because of this is the hardest to treat.
- Flap tear: A flap tear occurs when a piece of the meniscus is partially detached and flips over, creating a flap. This type of tear may cause the knee to lock or catch during movement.
- Horizontal tear: Runs along the curve surface of the meniscus. Occurs in the area with blood flow.
- Bucket handle tear: Runs in the center of the meniscus, which often cause the knee to become stuck and blocks knee motion. This type of tear can cause the knee to lock up and may require surgery to repair.
- Complex tear: A combination of tear patterns are seen (i.e. radial tear combined with a horizontal tear). This type of tear can be more difficult to treat and may require surgery.
- Intrasubstance/Incomplete tear: Typically occurs as a result of wear and tear and gets worse over time.
Is physical therapy a treatment option for a meniscus tear?
Physical therapy is often an important part of treatment for meniscus tears. Physical therapy can help to reduce pain and swelling, improve range of motion and strength, and promote healing of the injured meniscus. A physical therapist can create an individualized exercise program that is tailored to the patient’s specific needs and goals, taking into account the type and severity of the meniscus tear, as well as any other injuries or conditions that may be present.
In some cases, surgery may be needed to fully repair damaged tissue. However, for most meniscus tears, these exercises may be helpful in promoting healing and improving strength and mobility:
1. Straight-leg raises: Lie on the back with one leg straight and the other bent. Lift the straight leg off the ground, hold for a few seconds, and then lower it back down. Repeat 10 times, then switch legs.
2. Hamstring curls: Lie on the stomach with legs straight. Slowly bend your knee to lift the foot of the injured side towards the buttocks. Slowly lower your foot back down to the ground. Repeat on the other leg and for 8 to 10 times.
3. Calf raises: Stand with your feet hip-width apart and a chair in front of you for support. Flex the foot that is extended and tighten thigh muscles. Slowly raise the foot that is flexed to 45 degrees. Lower leg, and repeat on the other leg. Do a total of 25 repetitions on each leg.
4. Quadriceps settings: Sit with your legs straight out in front of you. Tighten the muscles on the front of your thigh, pressing your knee down into the ground. Hold for 10-20 seconds, and then release. Repeat 10 times with 30 seconds to 1 minute rest in between sets.
5. Clams: Lie on the uninjured side, with hips stacked on top of one another and knees bent at 45 degree angle. Rest head on lower arm and use top arm to stabilize your position. While feet are stacked, slowly raise top knee as far as possible without moving lower back and pelvis. Return top knee to starting position. Repeat 8 to 12 times.
6. Mini-squats: Stand with back against wall with shoulders and head against the wall. Feet should be hip-width apart. Slowly bend your knees, keeping your back straight, until you are in a half-squat position. Hold for 10 seconds, and then slowly stand back up. Repeat 8 to 10 times.
7. Seated leg extensions: Sit on a chair with your feet flat on the ground. Flex one foot then lift straightening the leg. Slowly lower the leg to starting position. Repeat 10 times, then start on the other leg.
8. Prone hang: Lie face down on bed or bench with legs extended over the edge. Let gravity slowly pull one knee down until fully extended. Hold for 15 to 30 seconds before bringing the leg back up. Repeat 3 times then do the same on the other knee.
These exercises can be done as part of a comprehensive physical therapy program or on their own, but it’s important to consult with a healthcare provider before starting any new exercise program, especially if you have an injury such as a meniscus tear.
What are the types of exercises to avoid?
While exercise is generally beneficial for overall health and recovery from injuries, there are some exercises that may aggravate a meniscus tear and should be avoided until the injury has healed.
- High-impact activities: Activities involving running, jumping jacks, or plyometrics
- Deep squats and Lunges: These both can put a lot of pressure on the knee joint and exacerbate a meniscus tear.
- Twisting movements: Exercises that involve twisting or pivoting on the knee, such as playing basketball or soccer, can increase the risk of further injury to a meniscus tear.
- Free weights: To make any other above exercises harder.
It’s important to avoid these exercises until you have fully recovered from your injury. A healthcare provider or physical therapist can help you create an individualized exercise plan that takes into account your specific injury and goals
What is the recovery time for meniscus tears?
The recovery time for a meniscus tear can vary depending on several factors, including the severity and location of the tear, the age and overall health of the patient, and the treatment approach used. In general, the recovery time for a meniscus tear can range from 4 to 8 weeks to up to 6 months depending on the severity. Typically for minor tears, treatments such as the RICE method and physical therapy may be used which will only take a few weeks for healing. However, for more severe cases, surgery may be warranted which may involve months of healing.
