A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae. Menisci can be torn during innocuous activities such as walking or squatting.
Symptoms include pain, swelling, and bruising to the front of the knee. [1] A person may also be unable to walk. [1] Complications may include injury to the tibia, femur, or knee ligaments. [2] It typically results from a hard blow to the front of the knee or falling on the knee. [1] The patella can also be fractured indirectly.
Often there is sudden onset of pain and walking is difficult. [1] In a complete rupture, the ability to extend that knee is decreased. [1] A pop may be felt when it occurs. [2] Injury to the patellar tendon generally requires a significant force such as falling directly on the knee or jumping from a height. [1]
Injury. The tear of meniscus is among the most common knee injuries. It is usually caused by torsional stress; twisting or turning of the knee too quickly with the foot planted on the ground while the knee is flexed. The feeling of a "pop" in the knee is usually felt when the meniscus is torn.
Arthritis is a common symptom of SLE. Arthritis is often symmetric and more often involves small joints. Though almost any joint may be affected, the knees and joints of the hands are most often involved in SLE. In larger joints (including the knee), avascular necrosis is a possible complication, leading to further pain and disability. [12]
Foot injuries including plantar fasciitis is another source of pain which is associated with-standing for long periods. [ 1 ] [ 6 ] There are three major tendons that maintain stability at the ankle joint; anterior extensors , medial flexors and lateral peroneal , these tendons facilitate movement around the ankle, foot and toes.

Dysfunction of a single nerve such as the common peroneal nerve is called a mononeuropathy. Mononeuropathy means the nerve damage is occurred in one area. However, certain conditions may also cause single nerve injuries. [4] Common causes of damage to the peroneal nerve include the following: Traumatic injury on the knee; Fracture of the fibula
Around half of ACL injuries occur in conjunction with injury to other structures in the knee, including the other ligaments, menisci, or cartilage on the surface of the bones. A specific pattern of injury called the "unhappy triad" (also known as the "terrible triad," or "O'Donoghue's triad") involves injury to the ACL, MCL, and medial meniscus ...
