What Causes Pain In The Knees?

Torn Meniscus

The meniscus is a thin piece of cartilage that provides cushioning between the bones of the shin and thigh. Each knee has two menisci, and these may tear as a result of the forceful rotation of the knee. Kneeling, squatting, or making sudden stops or turns could cause a torn meniscus. Patients with this injury might observe swelling and stiffness in the knee, and it could be difficult to fully straighten the joint. The knee may feel locked into place. To evaluate this injury, doctors perform a physical examination that includes watching the patient walk and squat. MRI scans will be needed, and an arthroscopy could be recommended in some cases. If a torn meniscus is confirmed, doctors usually start treatment with rest, ice, physical therapy, and pain relievers. Patients who continue to have severe pain or a locked knee after these conservative treatments will be considered for surgery. Children and young adults may be able to have a torn meniscus surgically repaired. If this is not an option for the patient, the surgeon will trim the meniscus instead.

Tendinitis

Tendinitis of the knee is normally caused as a result of a knee injury or inflammation in the area. The patellar tendon, a band of tissue that connects the patella and tibia, is an especially common site for tendinitis. Patients with this condition may have pain at the base of the kneecap, and this could progress to a burning sensation. Pain might increase while kneeling or squatting, and mild swelling may develop. When tendinitis first begins, patients will typically notice intermittent pain after exercise. As the condition advances, pain becomes more constant, and it could disrupt sleep and sports performance. Daily activities such as using stairs or riding in a car could become very painful. Tendinitis is generally treated with physical therapy, rest, ice, anti-inflammatories, and activity modification. Some patients may recover in a few weeks, and others could experience symptoms for several months.
