"Subchondral insufficiency fracture of the knee (SIF/SIFK) are stress fractures in the femoral condyles or tibial plateau that occur in the absence of acute trauma, typically affecting older adults."

"This entity subsumes what was previously known as spontaneous osteonecrosis of the knee (SONK/SPONK) or Ahlbäck disease. Recognising that spontaneous osteonecrosis of the knee was a misnomer and actually represents a subchondral insufficiency fracture that progressed to subchondral collapse with secondary osteonecrosis, the Society of Skeletal Radiology Subchondral Bone Nomenclature Committee recommended that "subchondral insufficiency fracture" be the preferred term 17."

"On radiographs, the Koshino classificiation is often used (c. 2022) to determine treatment 18:"
"Fractures stage III or or IV may be considered for arthroplasty, while non-operative management can be considered for stages I or II 18."
