M23.032
Cystic meniscus, other medial meniscus, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Cystic meniscus refers to the formation of a cyst associated with the meniscus of the knee, specifically affecting the medial meniscus on the left side. The menisci are C-shaped pieces of cartilage that act as shock absorbers between the thigh bone (femur) and shin bone (tibia). When a cyst develops in or around the meniscus, it can lead to joint discomfort and functional limitations. This condition is often linked to joint injuries, degeneration, or tears within the meniscus tissue.
Causes & Symptoms
Clinical Causes: Meniscal tears resulting from trauma or injury Degenerative changes due to aging or wear-and-tear Repetitive stress or overuse of the knee joint Previous knee injuries increasing vulnerability to cyst formation Congenital anomalies or structural abnormalities
Key Symptoms: Knee pain, especially with movement or bearing weight Swelling or a feeling of fullness in the knee joint Restricted range of motion or stiffness A clicking, locking, or catching sensation during knee movement Tenderness around the medial side of the knee Possible sensation of instability or giving way
Diagnostic & Treatment
Diagnosis Path: Diagnosing a cystic meniscus involves a combination of medical history assessment and physical examination. A healthcare provider may perform specific tests to evaluate joint stability and identify tender or painful areas. Imaging studies are crucial for confirmation. These include:
Treatment Protocols: Conservative management with rest, ice, compression, and elevation (RICE) Physical therapy to strengthen muscles around the knee and improve joint stability Pain management with non-steroidal anti-inflammatory drugs (NSAIDs) Intra-articular corticosteroid injections to reduce inflammation Surgical intervention, such as arthroscopic surgery, to remove or repair the meniscus and drain the cyst Post-surgical rehabilitation to restore knee function and strength
