End Stage Hoffa’s Disease Presented as a Giant Osteochondroma: Case Report and Literature Review

Abstract

Introduction: Hoffa’s disease appears to be an under-recognized ailment according to an extensive comprehensive literature assessment. Predisposing factors in sports training include torsion and hyperextexion at the knee should be taken into consideration when evaluating patients with chronic knee pain. We present the case of a young soldier suffering from left knee pain as a result of Hoffa’s disease Case report: A 29-year-old male patient admitted to orthopedic department to assess an anterior mechanical pain on the left knee. He reported that he had a sport accident with notion of hyperextension and anterior direct trauma to the left knee. On physical examination we found a painful mass that seems located under the patellar tendon, passive flexion of the left knee triggered a sharp pain from 100°. On X ray we found bone-like mass located behind the silhouette of the patellar tendon without attachment to the bones of the leg. MRI identified a 4.2 osseous tumor with no attachment to the patellar tendon. A surgical excision was preformed Conclusion: Hoffa disease is relatively a rare illness, its physiopathology is not yet completely clear. But many cases have been reported in literature. Its clinical presentation is not very specific, and its surgical excision which remains unavoidable, guarantees satisfying clinical and functional results. However, it remains to be determined whether it is a definitive solution in the context of “Hoffa’s disease”.
