The term "torn meniscus” usually refers to the damage of meniscus of the knee joint.
Diagnosis is made on the basis of the following :
Additional investigations include:
Conservative treatment modalities for torn meniscus include the following.
Surgical treatment consists of the following:
Rehabilitation therapy includes:
Prognosis of the condition after medical and surgical repair is good. Even the athletes and gymnasts, who are involved in excessive activity, achieve good level of healing and repair within 4 to 6 weeks. Healing time depends on dedication to physiotherapy and adherence to rehabilitation program.
Complications of meniscectomy are rare (2%) and rarely does the condition recur with proper care. However, lack of care can result in gross morbidities like deviated gait.
The prevalence rate of torn meniscus is 61:10,000. A male is to female predisposition of 2.5:1 has been found as males participate in sports more compared to females. No racial predisposition exists.
In males, menisci are prone to tears in the age of 31 to 40 years. Females are susceptible during 11 to 20 years of age. In children younger than 10 years of age, these injuries are rare due to more elasticity of the menisci.
It is common in individuals performing sports activities. Approximately 60% of the patients are prone to a torn meniscus over the age of 65.
Meniscus is a fibrocartilaginous structure that partially covers the various joints of the body, including the knee joint. Knee menisci are two in number (lateral and medial) and are C-shaped flaps that function to reduce the friction between the femur and upper end of tibia by providing a cushioning effect.
Tears of menisci may occur due to excessive grinding of femur into the tibia or due to thinning of menisci with age. The medial meniscus is firmly attached to the cruciate ligament whereas the lateral meniscus is not and is relatively more mobile as compared to the medial meniscus. This accounts for tears of medial meniscus being more common as compared to the lateral meniscus.
Depending upon the morphology, tears are of various types including :
If the injury occurs in well-perfused region of the joint, healing is more likely to occur as compared to scarcely perfused areas.
Torn meniscus refers to the tear in meniscus surrounding the knee joint as a result of direct trauma or as a progressive degenerative phenomenon . Menisci are fibrocartilaginous structures that surround many joints of the body but the term “torn meniscus” conventionally refers to the damage of meniscus of the knee joint.
Inflammation and swelling of the knee joint are common symptoms of the disease. Conservative treatment modalities are employed for the relief of symptoms and surgical interventions are used for repair.
Torn meniscus refers to the condition when one of the protective cushioning layers around the knee joint known as “meniscus” gets torn. The cause of damage is excessive grinding of the joint while squatting, kneeling or while bearing heavy weights. Alternatively, the meniscus may also get torn in old age as a result of wear and tear changes that occur with age.
The affected knee becomes swollen and painful. The pain worsens on movement and the range of motion is decreased. The effective treatment plan is to rest the knee, apply cold packs and elevate the leg to avoid putting undue strain on the knee. Drugs are given for swelling and pain. In extreme cases, surgery is done for repair or removal of the damaged menisci.
Once repaired, care should be taken to avoid straining the already weakened menisci. With proper care and treatment, healing occurs within 4-6 weeks.
