A case report of an adult with bilateral osteochondritis dissecans of the femoral condyles in both knees.

Introduction: There are several possible treatment options for the treatment of focal cartilage defects in the knee. Determining the appropriate treatment option to compensate for an osteochondral defect caused by osteochondritis dissecans (OCD) in adults is difficult. This study was conducted to clarify the importance of Autogenous Osteochondral Grafting by a mosaicplasty method in treating OCD, relieving pain, and improving knee function.

Case report: Hydatid cyst of bone in the distal femur with untypical presentation treated surgically.

Introduction: Osseous form is a rare manifestation of hydatid cystic disease, and it is easily misdiagnosed for other musculoskeletal infections and tumor-like lesions as it presents in a solitary form with subtle and unspecific radiological features and clinical symptoms.

Case Report: Our study is a case report of a young female patient with hydatid cyst in the distal femur, who was treated successfully with surgical resection, conducted in 2021 and the case was followed up for 8 months.

Discussion: Several cases had been reported of osseous hydatidosis commonly in the axial skeleton and often diagnosed lately, stressing the importance of keeping unfamiliar diagnosis in mind when dealing with untypical lesions of bone.
