Nonoperative Management of Tibial Stress Fractures Result in Higher Return to Sport Rates Despite Increased Failure Versus Operative Management: A Systematic Review

Purpose: To compare return to sport (RTS) rates and complications after nonoperative versus operative management of tibial stress fractures. Methods: A literature search was conducted per the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using EMBASE, PubMed, and Scopus computerized data from database inception to February 2023. Studies evaluating RTS sport rates and complications after nonoperative or operative management of tibial stress fractures were included. Failure was defined as defined by persistent stress fracture line seen on radiographic imaging. Study quality was assessed using the Modified Coleman Methodology Score. Results: Twenty-two studies consisting of 341 patients were identified. The overall RTS rate ranged from 91.2% to 100% in the nonoperative group and 75.5% to 100% in the operative group. Failures rates ranged from 0% to 25% in the nonoperative groups and 0% to 6% in the operative group. Reoperations were reported in 0% to 6.1% of patients in the operative group, whereas 0% to 12.5% of patients initially managed nonoperatively eventually required operative treatment. Conclusions: Patients can expect high RTS rates after appropriate nonoperative and operative management of tibial stress fractures. Treatment failure rates were greater in patients undergoing nonoperative management, with up to 12.5% initially treated nonoperatively later undergoing operative treatment. Level of Evidence: Level IV; Systematic Review of level I-IV studies.
