ABSTRACT
Legg-Calvé-Perthes disease (LCPD) is an idiopathic necrosis of the femoral head in childhood, the deformities of the femoral head occurring in the progress of disease could result in osteoarthritis. Treatment can be surgical or nonsurgical, but the timing and indications remain unclear. Understanding of the prognostic factors of LCPD is helpful to predict the outcome and guide the clinical management. This study reviewed the literatures about the prognosis of LCPD since 2000, the prognostic factors were summarized from three categoriesas general factors, disease factors and intervention factors. The general factors were the characteristic information of patient that can be obtained at the first time clinically. The age of onset is the most definite prognostic factor, the younger the age, the better the prognosis, and 6-8 years is an important watershed. Disease factors refer to the disease characteristic information obtained through evaluation. The modified Waldenstr?m stage of the disease needs to be confirmed first, early treatment can ensure better prognosis. Then the severity was evaluated, including the involvement of necrosis, morphological changes and extrusion of the femoral head. The more severe the disease, the worse the prognosis. Most predicters, such as Catterall grading and Herring lateral column typing, have to be used in late-stage of LCPD. The degree of femoral head perfusion evaluated in enhanced MRI or DWI-MRI is an early predictor of LCPD, but it is still in the preliminary exploratory. Intervention factors are the effects of different methods of treatment on prognosis, including the comparison of surgery or non-surgery, different non-surgical and different surgical methods. The determination of surgical or non-surgical treatment mainly depends on the age of onset and severity of disease, and the younger and milder cases tend to be non-surgical treatment, but the specific indications are still controversial.
