title: [Microcrystalline stress in the pathogenesis of osteoarthritis].
abstract: OBJECTIVE
  To estimate the rate of articular cartilage microcrystallization in osteoarthritis (OA).
  
  
  METHODS
  The investigation included 110 people who had undergone total endoprosthetic replacement for coxarthrosis. A total of 50 patients with total hip endoprosthetic replacement for femoral neck fractures were recruited as a comparison group. An X-ray diffractometer was used to detect crystals.
  
  
  RESULTS
  Cartilage mineralization was seen in 72% of the patients with late-stage OA.
  
  
  CONCLUSIONS
  Articular cartilage microcrystalline stress is a constant sign of late-stage OA requiring further clinical interpretation.
