We report a case of a 31-year-old man with a 5-year history of snapping knee syndrome secondary to a single, large symptomatic fabella of the knee. On physical examination, the patient was able to reproduce an audible and palpable snapping with active range of motion. His condition was refractory to physical therapy. He had undergone a prior iliotibial band release at an outside facility. After excision of the fabella, measuring 15 × 8 × 9 mm, the patient’s snapping and pain with activity were resolved.
