Early Onset Rapidly Progressive Osteoarthritis of the Hip in a Young Athlete.

We report and discuss a very rare case of early-stage rapidly progressive osteoarthritis (RPO) in a 33-year-old female athlete. The etiopathology of RPO remained unclear, although in this case mechanical overloading due to constant joint overuse appeared to be the only significant contributing factor to the very early development of RPO. Key words: rapidly progressive osteoarthritis, rapid destructive arthrosis, hip arthrosis, total hip arthroplasty, athlete, osteoarthritis.
