Introduction: Pellegrini–Stieda syndrome, characterized by medial collateral ligament (MCL) calcification or ossification, often follows a history of trauma. While rare, its distinct radiographic features pose diagnostic challenges. Conservative treatments are effective for many, but surgical intervention is necessary when they fail. Case Report: A 31-year-old male with knee pain and stiffness, an inability to extend his knee, and a fixed flexion deformity. Radiological examinations confirmed heterotopic ossification along the MCL, indicating post-traumatic Pellegrini–Stieda syndrome. Despite 3 months of conservative treatment, the patient’s pain persisted, leading to surgical excision. The surgical approach involved diagnostic arthroscopy, revealing arthritic changes and adhesions. Arthroscopic adhesiolysis and open excision of the ossified mass significantly improved the patient’s range of motion. Histopathological examination confirmed heterotopic bone formation. Follow-up appointments at 1, 3, and 6 months showed a pain-free and mobile knee joint, with the Pellegrini–Stieda lesion disappearing from radiographs. Conclusion: This case underscores the effectiveness of surgical intervention for refractory Pellegrini–Stieda syndrome, offering hope for improved patient outcomes and highlighting the importance of early diagnosis and tailored treatment in managing this rare condition. Keywords: Pellegrini–stieda syndrome, massive lesion, heterotopic ossification, arthroscopic adhesiolysis, medial collateral ligament.

“…The pathogenesis of this disease is thought to involve calcification of a posttraumatic hematoma, is diagnosed by a frontal x-ray view of the knee which will show calcification of the medial collateral ligament, and may also show ossifications superiorly on the medial femoral condyle. 12…”

The medial collateral ligament (MCL) is a major stabilizer of the knee joint. It is the most common ligament injured in the knee, particularly in athletes, and has been reported to be torn in 7.9% of all knee injuries. The MCL has a complex, layered anatomy with multiple insertions and functions. Minor trauma can cause tearing of the superficial portion whereas higher energy mechanisms can disrupt both the deep and superficial layers. History and physical are often adequate, but the gold standard for diagnosis is MRI. Lesser injuries to the MCL can often be treated conservatively with early rehabilitation, but more significant tears often necessitate surgery. A thorough understanding of the MCL and associated injuries is essential for proper diagnosis and treatment.
