Ossification of the medial collateral and lateral collateral ligament of knee in a 19-year-old female

This case report discusses an uncommon presentation of Pellegrini-Stieda syndrome (PSS), characterized by ossification of the medial collateral ligament (MCL) of the knee, extending to the lateral collateral ligament (LCL) in a 19-year-old female patient. Typically, PSS involves post-traumatic calcification of the MCL, but this case uniquely presents ossification in both the MCL and LCL, a phenomenon not widely documented. The patient, a young laborer from a lower socio-economic background, developed knee pain and restricted movement following a fall. Diagnostic imaging revealed the unusual ossifications, leading to a diagnosis of PSS. The patient was treated with steroid injections under fluoroscopic guidance, resulting in significant improvement in knee mobility. This report highlights the importance of recognizing atypical presentations of PSS for accurate diagnosis and treatment, emphasizing the need for further research into the underlying mechanisms and optimal management strategies for such cases.
