Snapping Knee Caused by Medial Meniscal Cyst

الملخص EN

Snapping phenomenon around the medial aspect of the knee is rare.

We present this case of snapping knee caused by the sartorius muscle over a large medial meniscal cyst in a 66-year-old female.

Magnetic resonance images demonstrated a large medial meniscal cyst with a horizontal tear of the medial meniscus.

Arthroscopic cyst decompression with limited meniscectomy resulted in the disappearance of snapping, and no recurrence of the cyst was observed during a 2-year follow-up period.
