Pellegrini-Stieda syndrome is an uncommon condition, often occurring after trauma, that involves the ossification or calcification of the knee’s medial collateral ligament (MCL). This process can lead to pain, stiffness, and restricted joint mobility. We describe the case of a 48-year-old patient who experienced left knee trauma 10 months earlier and underwent surgery for a patellar cartilage lesion three months ago. The patient presented with persistent knee pain and stiffness, prompting suspicion of Pellegrini-Stieda syndrome. Diagnosis was confirmed by X-ray and MRI. The patient was managed conservatively with rest, anti-inflammatory medications, and physiotherapy. Although symptoms continued, gradual improvement was observed, and no surgical intervention was necessary. This case underscores the importance of imaging, especially MRI, in accurately diagnosing and evaluating the extent of ossification, which helps guide treatment decisions and prevent premature surgery.
