  • Surgical treatment of anterior tibial stress fractures is associated with a high rate of symptom resolution and return to play in athletes,

  • The high complication rate and potential need for subsequent procedures are important considerations for surgeons and patients

  • Concurrent procedures such as ACLR prolonged the time to RTS, but it had no effect on the RTS rate and the level of sports activity at the time of RTS.
