This document describes a case of open arthrolysis performed on a 35-year old male farmer who presented with a stiff elbow of unusual etiology. An MRI revealed a soft tissue mass in the superior radioulnar joint. During open arthrolysis, an intra-articular ganglion was found and removed from the superior radioulnar joint. Post-operatively, the patient underwent physical therapy and elbow mobilization exercises to regain range of motion, achieving near full extension and flexion after six months with minimal pain.
