Return to sport and active military duty after cervical disc arthroplasty: A systematic review

Introduction: Cervical disc arthroplasty (CDA) has been established as an effective treatment for cervical disc degeneration or herniation in the general population. Return to sport (RTS) outcomes in athletes remain unclear. Objective: The purpose of this review was to evaluate RTS following single-level, multi-level, or hybrid CDA, with additional return to activity context provided by return to duty (RTD) outcomes in active-duty military. Methods: Medline, Embase, and Cochrane were searched through August 2022 for studies that reported RTS/RTD after CDA in athletic or active-duty populations. Data was extracted on the following topics: surgical failures/reoperations, surgical complications, RTS/RTD, and postoperative time to RTS/RTD. Results: Thirteen papers covering 56 athletes and 323 active-duty members were included. Athletes were 59% male with a mean age of 39.8 years and active-duty members were 84% male with a mean age of 40.9 years. Only 1 of 151 cases required reoperation and only 6 instances of surgical complications were reported. Classified as return to general sporting activity, RTS was observed in 100% of patients (n = 51/51) after an average of 10.1 weeks to training and 30.5 weeks to competition. RTD was observed in 88% of patients (n = 268/304) after an average of 11.1 weeks. Average follow-up was 53.1 months for athletes and 13.4 months for the active-duty population. Conclusion: CDA displays excellent RTS and RTD rates in physically demanding populations at rates superior or equivalent to alternative treatments. Surgeons should consider these findings when determining the optimal cervical disc treatment approach in active patients.
