Isolated patellofemoral osteoarthritis: A systematic review of treatment options using the GRADE approach

Background and purpose The optimal treatment for isolated patellofemoral osteoarthritis is unclear at present. We systematically reviewed the highest level of available evidence on the nonoperative and operative treatment of isolated patellofemoral osteoarthritis to develop an evidenced-based discussion of treatment options

Unicentric epithelioid hemangioendothelioma of the calcaneus: a case report and review of literature

Abstract Background This review of the literature combined with a clinical case will allow the illustration of a favorable outcome of this variable low grade malignancy, display a role for limb salvage surgery with intralesional treatment, and offer a clinical example of epithelioid hemangioendothelioma, a rare malignancy. Case presentation The case report presents a case of solitary epithelioid hemangioendothelioma (EHE) of the calcaneus in a 60-year-old male. Primary vascular tumors of the bone are rare; however, EHE is one of the most common primary malignant vascular tumors to occur in bone. A review of the literature found few cases that involved the calcaneus; those cases found that involved the calcaneus were either part of a multifocal or metastatic disease process. Our case presents a 45-month clinical follow-up of solitary EHE in the calcaneus treated with surgical excision by curettage and cementing. Conclusion This case has clinical follow-up greater than 2 years post-operatively and could be a guide for treatment of a rare disorder with a substantial paucity of literature
