In a prior study of marathon runners, we noticed that MR scans of the knee frequently each of the three groups was statistically significant at p < .05. In each case with hematopoietic bone marrow hyperplasia, the distal femur was the only area affected, while the epiphysis and proximal tibia were uninvolved. This pattern of affected bone marrow with hyperplasia of the hematopoietic marrow may be useful for the differential diagnosis.
