Pdf Summary

A systematic review and meta-analysis evaluated the prognostic value of MRI grading for time to return to sports and rate of return to sports after bone stress injuries. The review included 16 studies with a total of 560 bone stress injuries. The pooled data showed that higher MRI-based grading was associated with an increased time to return to sports. Combining all anatomic locations, the mean time to return to sports was 41.7 days, 70.1 days, 84.3 days, and 98.5 days for MRI grades 1, 2, 3, and 4 injuries, respectively. Trabecular-rich sites of injury took longer to heal than cortical-rich sites of injury. Overall, more than 90% of all athletes successfully returned to sports. The findings suggest that MRI grading may offer a prognostic value for time to return to sports after nonsurgical treatment of bone stress injuries. Individually adapted rehabilitation regimens and therapeutic decisions are recommended to optimize healing and a safe return to sports.
