“…5 In a very recent study that reviewed 27 patients with Pellegrini Stieda who underwent MRI, the sMCL was found to be the location in 8 patients, 7 patients had a solitary lesion of the posterior medial patellofemoral ligament (MPFL), and 12 patients had a combined lesion of these two structures. 23…”

The Pellegrini–Stieda Lesion Dissected Historically

The Pellegrini-Stieda lesion is a common finding on conventional X-rays. Whether it originates in the medial collateral ligament (MCL) of the knee or the medial head of the gastrocnemius muscle or another structure remains under debate. We discuss the difference in the articles by Pellegrini and Stieda and follow the vision on the origin of the lesion through time. A systematic research in PubMed/MEDLINE was conducted, identifying all articles on the Pellegrini-Stieda lesion and analyzing them for proposed origin of the lesion. The articles with their conclusion based on either finding during surgery or magnetic resonance imaging (MRI)/computed tomography were analyzed in more detail. Our PubMed/Medline search identified 4,997 articles. After exclusion of articles that were not on the Pellegrini-Stieda lesion and of doubles, 27 articles remained. By checking the references manually, 10 more articles were identified. Proposed origins were MCL, medial gastrocnemius, adductor magnus, vastus medialis, deep MCL, and superficial MCL. Although the MCL was most often coined as origin of the lesion (54% overall, 25% on MRI, and 57% during surgery), many cases remained undecided (50% on MRI) or no specific structure was found to be the origin (29% during surgery). There are diverse proposed origins of a calcification on the medial side of the knee. The eponymous term Pellegrini-Stieda lesion seems fitting, as it comprises two different thoughts on the origin of the lesion. MRI seems to be a noninvasive and quite accurate method for future research.

“…While, according to the cadaver study, Stieda held a different opinion that the lesion was located medial to the origin of the gastrocnemius medial head muscle ( 7 ). In subsequent studies and reports, the Pellegrini–Stieda lesion can also involve the adductor magnus tendon and posterior attachment of medial patellofemoral ligament (MPFL) ( 5 , 14 , 20 ). From the MRI of our case, the ossification lesion involved MCL and medial joint capsule.…”

Pellegrini–Stieda lesion is described as ossification on the origin of medial collateral ligament. We present a case of end-stage knee osteoarthritis with the Pellegrini–Stieda lesion treated by unicompartmental knee arthroplasty (UKA). During the postoperative follow-up, an interesting change occurred such that the ossification lesion disappeared gradually and did not relapse. It is supposed that the disappearance was caused by UKA changing the abnormal biomechanics of the varus osteoarthritic knee.

“…Pellegrini–Stieda syndrome is a rare knee condition characterized by calcification or ossification of the MCL, typically occurring at its proximal attachment [ 3 ]. The exact location of the Pellegrini–Stieda lesion remains debated, with possibilities including the MCL origin, medial to the gastrocnemius medial head muscle origin, and involvement of the adductor magnus tendon and posterior attachment of the medial patellofemoral ligament [ 1 , 2 , 4 - 6 ]. Mendes et al described four types of ossification: I: Beak shaped with inferior orientation and union to the femur, II: Drop shaped with inferior orientation and parallel to the femur, III: Elongated with superior orientation, and IV: With superior orientation and inferior attached to the femur [ 4 ].…”

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.
