Intraosseous ganglion in the subchondral region of the lateral femoral condyle in an 11-year-old girl: a case report

We report the case of a patient with intraosseous ganglion in the lateral femoral condyle. An 11-year-old girl presented with right knee pain following a twisting injury. Plain radiographs of the knee showed a small circumscribed radiolucency with a thin sclerotic margin in the subchondral region of the lateral femoral condyle. Although the image findings and location are not typical, the lesion was tentatively diagnosed as osteochodritis dissecans. Six months after the conservative treatment with a break from vigorous sports activities, the size of the bony lesion had not decreased. Thus, we performed arthroscopy to make a definitive diagnosis. Arthroscopic examination revealed an area with dimple and surface irregularity at the lateral femoral condyle. On excision of the overlying tissue, the lesion was cystic containing brown mucous fluid. No association between the cyst and the articular structures was observed. Histologic examination of the resected cyst wall showed dense fibrous tissue with spotty areas of calcification. Base on these findings, we made a diagnosis of intraosseous ganglion. At the nine-month postoperative follow-up, the radiographic examination showed healing of the lesion. We speculate that the lesion in this case might have occurred as a result of repetitive overstress or microtrauma

Large infrapatellar ganglionic cyst of the knee fat pad: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Large ganglionic cystic formations arising from the infrapatellar fat pad are quite uncommon and only a few are mentioned in the literature. An open excision in these cases is mandatory.</p> <p>Case presentation</p> <p>We report the case of a large infrapatellar fat pad ganglion in a 37-year-old Greek man with chronic knee discomfort. The ganglionic cyst originated from the infrapatellar fat pad and had no intrasynovial extension. The final diagnosis was determined with magnetic resonance imaging of the knee, and the lesion was treated with surgery.</p> <p>Conclusions</p> <p>These lesions are asymptomatic in most cases but often are misdiagnosed as meniscal or ligamentous lesions of the knee joint. Nowadays, the therapeutic trend for such lesions is arthroscopic excision, but when there is a large ganglion, as in this case report, the treatment should be an open and thorough resection. This report is intended mostly but not exclusively for clinical physicians and radiologists.</p

Intraarticular fractures of the distal radius treated with metaphyseal external fixation - Early clinical results

Twenty-two patients with unstable Frykman grade 7 or 8 intra-articular fractures of the distal radius were treated with an external fixator. The distal pins were inserted into the distal radial fracture fragments, permitting movement of the wrist and hand. Eleven patients were male and 11 female, with a mean age of 50 years. All patients had regained full function with good range of motion at mean final follow-up of 12 months. However function, pain and range of motion had returned to acceptable levels 4 weeks after removal of the external fixator. This method of external fixation provides a reliable method of maintaining fracture reduction whilst allowing early return of function
