The primary treatment involves the removal of loose bodies;however, their complete eradication is often challenging and may not address underlying diseases, leading to persistent symptoms and the risk of new loose body formation. Aim: This case report aims to present the findings and surgical management of a 52-year-old male with an unusually large osseous loose body in the knee joint and associated pathologies. Case Presentation: The patient, a 52-year-old male, experienced recurrent episodes of severe, sudden, and painful locking of the knee joint, leading to difficulties moving. A plain MRI study was conducted to evaluate the condition of the knee joint, which revealed various degenerative changes and the presence of a loose body. Subsequently, an arthroscopic examination was performed under general anesthesia, uncovering the presence of an abnormally large loose body, as well as other pathologies including chondropathy, meniscal degeneration, and Baker’s cyst. Conclusion: Loose bodies (LBs) in the knee joint pose significant challenges and may lead to debilitating symptoms. Timely diagnosis and appropriate surgical intervention are crucial for symptom relief and the prevention of further joint damage as arthroscopic excision. Comprehensive imaging has a vital role in guiding treatment decisions and optimizing patient outcomes. In this case, the removal of the loose body improved patient outcomes and helped prevent potential joint complications.展开更多

The appropriate management of these fractures is still controversial and only a few reports are available on this subject. We presented a case of a 37-year-old male with neglected fracture on the lateral process of talus which was misdiagnosed at the time of injury. The patient presented to 7 months after misdiagnosis with a chronic ankle pain. Our case is unique in the sense that it is a rare case of neglected fracture on the lateral process of taluswhich presented as a loose body in sinus tarsi. However, a surgery with an excision of the loose body presented a satisfactory outcome along with 2 years＇ follow-up. To our knowledge, it ought to he the first case reported in the English literature. Through this case report, we highlight the importance of high index of suspicion for such rare bony injuries while evaluating trauma to the lateral side of ankle and discuss the principles of management of these fractures.展开更多

They are usually asymptomatic and found as “incidentalomas” during Imaging. Their pathogenesis is not well known. We report a rare case of giant intraperitoneal mice which was clinically misdiagnosed as left seminal vesicle malignancy. A review of the literature is also presented.展开更多

This disorder affects a wide age range from adults to childhood with no sex dominance. Malignant transformation is rare to date, and there are approximately 34 cases in literature about the transformation of synovial chondromatosis to chondrosarcoma. Case: We present case of a 27-year-old patient who had synovial chondromatosis in his elbow. Discussion: Radiographic findings are usually pathognomonic for the diagnosis. Multiple calcified loose bodies can be seen in the joint in radiographs. Computed tomography (CT) optimally depicts the calcified intraarticular fragments and extrinsic bone erosion. However, because the radioopacity cannot be detected in 1/3 of the cases, diagnosis becomes difficult. Treatment modalities include arthroscopic or open extraction of the loose bodies and arthropasty in the presence of severe osteoarthritis. Conclusion: Synovial chondromatosis should be kept in the differential dignosis of the chronic monoarticular pain and painful limitations of the range of motions of the joints.展开更多
