Medial Hamstring Snapping Knee Syndrome: Case Report of an Unusual Presentation Due to Osteochondroma.

Abstract

Medial hamstring snapping knee syndrome is an infrequent clinical entity, with osteochondroma being an exceptionally rare etiology. This report details a case of a 21-year-old female presenting with a 4-month history of persistent left knee pain, snapping, and clicking, which developed following a fall. Despite initial conservative management, the symptoms persisted. Advanced imaging, including MRI, revealed a small osteochondroma on the medial aspect of the proximal tibia, which was the underlying cause of the snapping. A targeted physiotherapy regimen emphasizing quadriceps and hamstring strengthening was subsequently employed, leading to effective symptom management. This case highlights the necessity of a meticulous clinical evaluation and the role of advanced imaging in diagnosing rare etiologies of snapping knee syndrome. Furthermore, it demonstrates the efficacy of focused physiotherapy in managing such conditions.
