S83.26

Clinical Causes: Sudden twisting or pivoting movements, especially during sports or vigorous activities Direct trauma or impact to the knee, such as falling or a blow during contact sports Degenerative changes associated with aging, which weaken the meniscal tissue over time Repetitive stress or overuse injuries, particularly in athletes or individuals engaging in high-impact activities

Key Symptoms: Pain on the outer side of the knee, especially during movement or activity Swelling or tenderness around the knee joint Limited range of motion or difficulty fully extending or bending the knee A sensation of the knee locking or catching during movement Instability or a feeling that the knee might give way Persistent discomfort after activity or injury

Diagnosis Path: Diagnosis typically involves a thorough physical examination by a healthcare professional, who may assess knee stability, swelling, and pain. Imaging tests such as MRI (Magnetic Resonance Imaging) are commonly used to visualize the tear, determine its size and location, and rule out other injuries within the knee. X-rays may be performed to exclude bone fractures or other structural issues but do not directly reveal soft tissue injuries like meniscal tears.

Treatment Protocols: Treatment approaches vary depending on the severity of the tear, the patient’s activity level, and overall health. Options include: - Rest and activity modification to reduce stress on the knee - Application of ice to decrease swelling and pain - Use of non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy aimed at strengthening the muscles around the knee and improving joint stability - In some cases, minimally invasive surgery such as arthroscopic meniscus repair or removal (meniscectomy) may be necessary to restore knee function and alleviate symptoms. Recovery times vary based on the severity of the injury and the chosen treatment method, with surgical options generally requiring a longer rehabilitation period.
