Return to play after spondylolysis: An overview.

Spondylolysis is increasingly associated with specific sports, timely and effective management of which underpins successful return to sports. Hence, the main purpose of this systematic review of reviews [RoR] is to summarize data from published reviews exploring the return to play in athletes with spondylolysis managed conservatively or surgically, thereby providing for recommendations for future practice and research. A systematic review of review of articles published in English and since 2015 was conducted online using PubMed and Google Scholar, as per Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines. Predefined eligibility criteria were applied, and the data thus compiled were analyzed. Study quality was assessed using the AMSTAR-2 checklist. A total of 7 systematic reviews and meta-analysis consisting of 51 primary studies were included in the review. The result of this RoR highlights the knowledge gap and limitations in RTP research post spondylolysis with existing heterogeneity in methods and reporting amid other factors within primary studies. Further quality of the study was found to be of low to critically low confidence based on the AMSTAR-2 scale, suggesting that the results should be interpreted with great caution. Though both conservative and surgical approaches increase the percentage of athletes returning to play, the evidence remains largely limited and inconclusive as to which is better. However, it appears that surgical interventions give those who failed a trial of conservative approach, a better shot at return to play. There is a need for further high-quality, appropriately powered, well-designed, multicentered studies, and also for consensus regarding "returning to play" definition and outcome measures.
