S83.281

Clinical Causes: Sudden twisting or pivoting movements during sports or physical activities Direct trauma or impact to the knee, such as a blow or collision Degenerative changes associated with aging, leading to weakening of the meniscus Overuse or repetitive stress on the knee joint Poor landing techniques during jumping activities

Key Symptoms: Pain localized on the outer side of the knee Swelling and stiffness in the affected knee Difficulty fully straightening or bending the knee A feeling of the knee catching, locking, or giving way Tenderness along the joint line Loss of range of motion

Diagnosis Path: Diagnosis typically involves a combination of physical examination and imaging tests. Healthcare professionals may perform maneuvers to assess knee stability, pain response, and range of motion. Imaging procedures such as MRI scans are essential for confirming the presence and extent of the tear, as they provide detailed visuals of soft tissues like the menisci. X-rays may be used to rule out associated bone injuries.

Treatment Protocols: Treatment options vary depending on the severity and location of the tear, as well as the patient's activity level. Common approaches include: - Rest and activity modification to allow healing - Applying ice packs to reduce swelling - Compression with knee braces or wraps - Elevation of the leg to decrease inflammation - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy to strengthen surrounding muscles and restore function In cases where conservative treatment does not alleviate symptoms, or if the tear is complex or unstable, surgical options might be considered. Arthroscopic surgery can be performed to repair or remove the torn meniscal tissue, promoting quicker recovery and reducing the risk of future joint problems.
