Therapeutic methods range from conservative treatments, such as partial weight bearing, pharmaceutical interventions, and physical therapy, to surgical procedures in cases of advanced joint collapse. Available evidence from histological studies consistently shows the absence of bone necrosis, highlighting microfractures and bone remodeling as central features of these lesions.

This clinical problem stems from longstanding misclassification that has led to diagnostic confusion and inconsistent treatment approaches. Despite this progress, several unresolved issues persist. The precise biomechanical and biological factors that initiate SIFK remain unclear, and the optimal timing for intervention is still debated. In addition, long term outcomes of both nonoperative and operative treatments have yet to be definitively established.
