S83.289

Clinical Causes: Sudden twisting or pivoting movements while the foot is planted, common in sports like basketball, soccer, and football. Degeneration of the meniscus due to aging or repetitive stress, especially in older adults or people with joint wear-and-tear. Direct trauma to the knee, such as a blow or collision during contact sports or accidents. Overuse injuries from repetitive activities that strain the knee joint over time.

Key Symptoms: Pain along the outer (lateral) part of the knee, which may worsen with activity. Swelling or stiffness in the knee joint. A sense of the knee catching or locking during movement. Difficulty fully straightening or bending the knee. Tenderness when applying pressure to the outer knee area. Sensations of instability or the knee giving way.

Diagnosis Path: Diagnosing a tear of the lateral meniscus typically involves a healthcare professional conducting a physical exam focused on pain points, swelling, and joint stability. Imaging tests such as MRI scans are common tools used to confirm the presence, location, and extent of the tear, especially in cases where the injury is not obvious through physical examination alone.

Treatment Protocols: Treatment options vary depending on the severity of the tear, the patient's activity level, and overall health. Approaches may include: - Rest and avoiding activities that aggravate symptoms. - Ice application to reduce swelling. - Compression and elevation for symptom management. - Non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain and inflammation. - Physical therapy exercises to strengthen surrounding muscles and improve joint stability. - In some cases, surgical intervention such as arthroscopic meniscectomy or repair may be necessary, especially for complex or persistent tears. Recovery time depends on the severity of the injury and chosen treatment, with non-surgical approaches often requiring several weeks of rehabilitation, and surgical options potentially extending recovery periods.
