Subchondral insufficiency fracture of the knee (SIFK) is an important differential diagnosis for knee pain. If diagnosed early, SIFK can be treated conservatively with non-weight bearing ambulation. If left untreated, this disease may lead to catastrophic complications such as subchondral fragment detachment and fragmentation or subchondral collapse which will warrant the need for surgical intervention. The author reports a 44-year-old triathlete that presented with complaint of a trivial left anteromedial knee pain for one-year duration. This disease presented at an unusual site of the medial tibial condyle. Moreover, the patient is a healthy triathlete that does not have any predisposing factors for SIFK. Magnetic resonance imaging showed subchondral insufficiency fracture of the medial tibial condyle with a complex multi-directional medial meniscus tear in the same knee. Could the undiagnosed medial meniscus injury be the causation leading to the development of SIFK? Here, the author will summarize the literature on various clinical features, work-up and management of SIFK.
