A torn meniscus is a common and painful knee injury, especially among athletes. The meniscus is a C-shaped piece of cartilage in the knee, and it can be torn by any activity that causes you to twist or rotate your knee. This injury can be treated non-surgically with rest, ice, compression, elevation, pain medication, and physical therapy. More serious tears may require arthroscopic surgery, which can be followed by up to six additional weeks of recovery and physical therapy. Certain exercises can help speed up recovery, but it is important to consult a doctor or physical therapist to ensure safety.

What You'll Learn
Rest and physical therapy
Physical therapy can then help to rebuild strength and flexibility in the injured knee. The duration of physical therapy depends on the severity of the tear. For a small tear, a doctor may recommend four to eight weeks of physical therapy. This can include exercises such as mini-squats, standing heel raises, and hamstring heel slides, which can help to strengthen the quadriceps and large muscles at the front of the thigh. Physical therapy can also include low-impact exercises such as stationary biking, which can reduce pain, improve mobility, and restore function to the area around the meniscus tear.
For more serious tears, physical therapy may continue for eight weeks or longer. In some cases, surgery may be required, which can extend recovery time by an additional six weeks, followed by further physical therapy. Physical therapists can create personalized treatment plans to help patients return to their everyday activities. This can include strengthening the thigh and leg muscles and stretching the knee, thigh, and leg to restore the full range of motion to the knee.
Overall, rest and physical therapy play crucial roles in healing meniscus tears, with the duration and intensity of physical therapy depending on the severity of the injury.

Surgery options
Surgery is usually recommended for a torn meniscus if non-surgical treatments have not been effective in managing symptoms, or if the tear is severe. The type of surgery performed depends on the location, size, and morphology of the meniscus tear.
There are three types of meniscus surgery: meniscus repair, partial meniscectomy, and meniscus replacement. Meniscus repair involves stitching the tear together so that it heals back into one piece. This is more likely to be performed for tears in the "red zone", which comprises about 25% of the meniscus and receives blood flow. For tears in the "white zone", which does not receive blood flow, a partial meniscectomy is often performed. This involves trimming or removing the damaged part of the meniscus while leaving healthy tissue in place.
A meniscus replacement, or meniscus transplantation, is less common and is usually only an option for people younger than 50 who have knee arthritis or a severely torn meniscus. In this procedure, the surgeon replaces the meniscus with an allograft (a meniscus from a human donor).
Meniscus surgery is typically performed as a minimally invasive knee arthroscopy, where the surgeon makes a few small incisions in the skin around the knee and inserts tiny tools and a small camera into the joint. The surgery usually takes around an hour, and patients can often go home the same day. However, recovery can range from a few weeks to several months, depending on the type of surgery and the patient's activities. For example, meniscus repair recovery can take up to six to nine months, and surgeons recommend refraining from playing sports during this time.

Non-steroidal anti-inflammatory drugs
NSAIDs are frequently used by sports medicine physicians to treat athletes in pain. However, it is important to note that there is a lack of high-quality evidence to guide the use of NSAIDs. They have been found to have adverse effects, and their potential negative consequences on the long-term healing process are becoming more apparent. As such, they are not recommended for muscle injuries, bone fractures, or chronic tendinopathy. If NSAIDs are chosen as a treatment, they should be used for the shortest duration possible, taking into account the specific type of injury, the level of dysfunction, and pain.
Meniscus tears are a common knee injury that can occur during activities involving twisting or rotating the knee while bearing weight. The meniscus is a C-shaped piece of cartilage in the knee, and tears can range from small to large and may occur due to wear and tear over time or from sports involving sudden twisting movements. Small tears often heal on their own, while larger tears may require surgery.
In addition to NSAIDs, treatment for meniscus tears may include rest, ice, compression, and elevation (RICE), as well as physical therapy to restore strength and flexibility to the knee.

Corticosteroids and anaesthetics
Corticosteroids are powerful anti-inflammatory medications that can help alleviate knee pain. They work by reducing blood flow and calming the immune system. Corticosteroids are usually injected directly into the knee by a trained professional under ultrasound guidance. This way, the medication stands a better chance of reaching the target area and effectively reducing pain.
Corticosteroid injections do not heal a meniscus tear, but they can reduce swelling and discomfort. The effects of corticosteroid injections are short-lasting, with profound effects lasting for an average of four to five weeks. In some cases, a single injection can provide relief for more than a year. However, once the medicine wears off, the knee pain may return. Some clinicians argue that cortisone may even stop the meniscus from healing. Therefore, it should only be considered if other medications and therapy are not helping.
Anaesthetics can be injected into the knee along with corticosteroids. The anaesthetic provides immediate pain relief, which wears off after a few hours.

Exercises to improve strength
A meniscus tear is a common knee injury that can occur from sudden twisting movements or wear and tear over time. The meniscus is a C-shaped piece of cartilage in the knee that provides stability and strength. While small tears can heal on their own with rest and physical therapy, larger tears may require surgery.
Isometric Contractions
This exercise works by keeping the body in a static position and contracting the muscles. Lie flat on the ground with your legs extended away from the body. Contract your quadriceps to push the backs of your knees toward the floor and hold this position for 5 seconds. Perform 2 sets of 10 contractions, resting for 30 seconds to 1 minute between sets. This exercise strengthens the quadriceps and stretches the hamstrings.
Leg Extensions
Leg extension exercises build strength in the thighs and can be performed safely multiple times a day. Sit on a chair or bench with your feet flat on the floor. Flex and lift your right foot, straightening your right leg, and then slowly lower it back to the starting position. Repeat this 10 times, and then do the same with the left leg.
Side-Lying Leg Lifts
This exercise works the hip abductors and the muscles of the buttocks. Lie on your left side, keeping your hips and feet aligned. Bend your knees 45 degrees and slowly raise your top knee as high as possible without moving your lower back or pelvis. Slowly lower your top knee to its starting position. Perform 2 sets of 8-10 repetitions, resting for about 1 minute between sets. Repeat on the right side.
Mini-Squats
Mini-squats help strengthen the quadriceps without putting too much pressure on the knees. Stand with your back, shoulders, and head against a wall, with your feet shoulder-width apart and about 1 foot from the wall. Slightly bend your knees, bringing your buttocks toward the ground, stopping at around 15 degrees. Hold this position for 10 seconds, and then slowly return to the starting position.
It is important to consult a doctor or physical therapist before beginning any exercise routine to ensure it is safe and appropriate for your specific condition.
