Case Report


Step aerobics is one of the most popular exercises with established benefits to cardiovascular status. This activity is associated with injuries which include patellar or talar chondral lesions, quadriceps tendinopathy, Achilles tendinopathy or tear, shin splints and muscle soreness. The purpose of this case report is to present two step aerobics athletes, suffering from anterior knee pain. We observed that their knee MR examination disclosed only suprapatellar fat pad edema. No other findings were noticed. In addition, we discuss the possible pathogenetic mechanism of this entity which has not been previously reported in the literature.
