Overview

Meniscus Tear
A meniscus tear is an injury to one of the two pieces of cartilage that cushion and stabilize the knee joint. It may occur during twisting or pivoting movements, particularly during sports, or develop gradually as the cartilage becomes less resilient with age. Pain, swelling, stiffness, catching, or difficulty moving the knee can occur.
Septic Arthritis
Septic arthritis is a serious infection of a joint caused by bacteria, viruses, fungi, or other microorganisms. The infection can cause sudden joint pain, swelling, warmth, redness, and difficulty moving the affected joint. Septic arthritis requires prompt medical evaluation and treatment because infection can rapidly damage cartilage and other joint structures.

Diagnosis

Meniscus Tear
Diagnosis is usually based on the history of injury, symptoms, and a physical examination of the knee. Specific movements and tests can help identify meniscal injury. X-rays may be used to assess bone problems or arthritis but do not directly show most meniscus tears. MRI can provide detailed images of the meniscus and surrounding structures when the diagnosis is uncertain or treatment planning requires it.
Septic Arthritis
Septic arthritis is diagnosed urgently using symptoms, physical examination, blood tests, imaging when appropriate, and analysis of joint fluid. A needle may be used to remove fluid from the affected joint for laboratory testing, including examination for microorganisms and inflammatory cells. Blood cultures may also help identify an infection that has entered the bloodstream.

Prevention

Meniscus Tear
Using proper technique, strengthening the muscles around the knee and hips, maintaining flexibility, and gradually increasing training intensity may reduce injury risk. Appropriate sports equipment and conditioning can help. Avoiding sudden increases in activity and using care during movements involving twisting or pivoting may also reduce risk. Previous knee injuries should be appropriately evaluated and rehabilitated.
Septic Arthritis
There is no guaranteed way to prevent septic arthritis, but prompt treatment of skin and other infections, good wound care, appropriate management of chronic illnesses, and proper care around joint surgery can reduce risk. People with artificial joints or weakened immunity should seek prompt medical attention for symptoms of infection.

Risk Factors

Meniscus Tear
Risk increases with activities involving twisting, pivoting, squatting, or sudden changes of direction. Athletes participating in football, basketball, soccer, skiing, and similar sports may be more exposed. Increasing age also raises risk because the meniscus becomes less resilient. Previous knee injury, joint degeneration, and repetitive occupational stress can contribute.
Septic Arthritis
Risk factors for septic arthritis include an artificial joint, recent joint surgery, injection drug use, bloodstream infection, weakened immunity, diabetes, rheumatoid arthritis, and other chronic illnesses. Older age and existing joint damage can also increase susceptibility. Any condition that allows microorganisms to enter the bloodstream can potentially contribute.
