Subchondral Insufficiency Fractures of the Knee: A Clinical Narrative Review

»Subchondral insufficiency fractures of the knee (SIFKs) are subchondral plate fractures with a prevalence of 2% to 4% of all knee injuries.»Magnetic resonance imaging is the gold standard for evaluating SIFK, while plain radiographs have limited the use in the diagnosis of SIFK.»Among patients with SIFK, 50% to 100% have meniscal pathology.»Medical therapies and standard treatments traditionally used in the management of knee osteoarthritis differ from recommended management of SIFK patients.»Randomized controlled trials and cohort studies with long-Term follow-up are needed to determine the optimal rehabilitation protocol, interventional therapy, and prognosis of SIFK patients.
