M23.011
Cystic meniscus, anterior horn of medial meniscus, right knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Cystic meniscus, specifically affecting the anterior horn of the medial meniscus in the right knee, is a condition characterized by the presence of a cyst within the meniscal tissue. The menisci are two crescent-shaped cartilage structures that cushion and stabilize the knee joint. When a cyst develops within the meniscus, it can cause discomfort and affect joint function. This condition is identified by the ICD-10 code M23.011, which helps healthcare providers record and track cases related to this specific knee issue.
Causes & Symptoms
Clinical Causes: Degenerative changes due to aging or wear and tear Trauma or injury to the knee, such as twisting or sudden impact Repetitive stress on the knee joint Previous meniscal tears leading to cyst formation during healing Weakness or instability in the knee joint
Key Symptoms: Knee pain, especially during movement or weight-bearing activities Swelling or a feeling of fullness in the knee Limited range of motion or stiffness A sensation of popping or catching in the knee joint Tenderness along the medial side of the knee Occasional locking or giving way of the knee
Diagnostic & Treatment
Diagnosis Path: Diagnosing a cystic meniscus involves a combination of clinical evaluation and imaging tests. A healthcare provider typically examines the knee for signs of swelling, tenderness, and reduced mobility. Imaging studies such as MRI scans are crucial, as they can clearly visualize the cyst within the meniscus, identify the extent of tissue involvement, and distinguish it from other knee pathologies.
Treatment Protocols: Managing cystic meniscus in the right knee may include conservative and surgical options, depending on the severity of symptoms and cyst size. Common approaches consist of: - Rest and activity modification to reduce stress on the knee - Physical therapy to strengthen surrounding muscles and improve joint stability - Non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief - Aspiration of the cyst, in some cases, to remove fluid - Arthroscopic surgery to remove or repair the damaged meniscus and excise the cyst, especially if symptoms persist or worsen Post-operative recovery typically involves physical therapy to regain strength and mobility, along with regular follow-up to monitor healing.
