Surgical Management of Snapping Quadriceps Caused by Distal Femur Osteochondroma: A Case Report.

INTRODUCTION

Osteochondromas, common benign bone tumors, can lead to complications such as snapping quadriceps when located near joints such as the knee. This case report discusses a rare instance of a distal femur osteochondroma causing a snapping sensation during knee movement. The pathogenesis involves the tumor altering the normal mechanics of the quadriceps tendon, necessitating a comprehensive diagnostic approach including magnetic resonance imaging and dynamic ultrasound.

CASE REPORT

We report a 37-year-old male who presented with a 6-month history of progressive pain, swelling, and a snapping sensation in the right knee, which was confirmed as a pedunculated osteochondroma with a cartilage cap <2 cm in thickness with appropriate investigations. Due to failed conservative management, the surgical resection through the Swashbuckler approach was performed.

CONCLUSION

The case emphasizes the importance of precise diagnostic imaging and tailored surgical intervention in managing uncommon mechanical complications of osteochondromas.
