M23.039
Cystic meniscus, other medial meniscus, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Cystic meniscus is a knee joint condition involving a cyst formation within or adjacent to the meniscus, particularly affecting the medial meniscus. The meniscus is a C-shaped cartilage structure that cushions the knee joint. When a cyst develops, it can cause discomfort, swelling, and restricted movement in the knee. This condition can occur in various parts of the meniscus but is often associated with degenerative changes or traumatic injuries. Proper diagnosis and management are essential to relieve symptoms and prevent further joint damage.
Causes & Symptoms
Clinical Causes: degenerative changes due to aging or wear and tear traumatic injuries from sports or accidents repeated stress or overuse of the knee joint meniscal tears leading to fluid accumulation and cyst formation prior knee surgeries or injuries that weaken meniscal tissue
Key Symptoms: localized knee pain, especially along the inner (medial) side swelling or a palpable lump in the knee stiffness and decreased range of motion locking or catching sensations during knee movement difficulty bearing weight or instability in the knee
Diagnostic & Treatment
Diagnosis Path: Magnetic Resonance Imaging (MRI) to visualize the cyst and meniscal damage X-rays to rule out other joint issues or bone abnormalities Arthroscopy may be performed if further assessment is needed and to confirm the diagnosis directly
Treatment Protocols: Rest and activity modification to reduce knee stress Physical therapy to strengthen muscles around the knee and improve stability Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation Aspiration of the cyst if accessible and symptomatic Arthroscopic surgery to remove or repair the damaged meniscus and drain or excise the cyst In some cases, meniscectomy (removal of part of the meniscus) or meniscal repair may be performed
