S83.201

Clinical Causes: Sudden twisting or pivoting movements, especially while weight-bearing Trauma resulting from sports injuries, such as football or basketball Direct blow or collision to the knee Degeneration of the meniscus over time, increasing vulnerability to tearing Rapid movements, such as jumping or changing direction abruptly

Key Symptoms: Pain localized around the knee joint, especially along the inner or outer side Swelling which may develop shortly after injury or over time Mechanical locking or catching sensation during knee movement Difficulty fully straightening or bending the knee Instability or a feeling that the knee might give way Tenderness when pressing on the knee

Diagnosis Path: Diagnosis typically involves a combination of physical examinations and imaging studies. The doctor will assess knee stability, swelling, and range of motion. Special tests, such as McMurray's or Apley's tests, may indicate meniscal injury. Magnetic Resonance Imaging (MRI) is particularly useful in visualizing the tear, confirming the diagnosis, and determining the extent of the meniscal damage. Sometimes, diagnostic arthroscopy, a minimally invasive surgical procedure, may be performed to view the inside of the knee directly and assess the injury accurately.

Treatment Protocols: Treatment options depend on the severity of the tear, the patient's age, activity level, and overall knee health. Common approaches include: - Rest, ice, compression, and elevation (RICE) to reduce swelling and pain - Non-steroidal anti-inflammatory drugs (NSAIDs) to manage discomfort - Physical therapy aimed at strengthening the muscles around the knee and improving stability - Arthroscopic surgery, often performed to repair or remove the torn meniscal tissue - Meniscus repair involves suturing the torn edges together - Meniscectomy involves trimming or removing the damaged part of the meniscus - Post-surgical rehabilitation to restore range of motion, strength, and function Recovery time varies, with some individuals returning to normal activities within a few weeks, while others may require several months of rehabilitation. Preventive measures include proper training techniques, adequate warm-up before activity, and using appropriate footwear.
