Reoperation Risks Between Cervical Disc Arthroplasty and Anterior Cervical Discectomy With Fusion
With nearly seven years of average follow-up, this large registry-based study showed that one-level CDA did not significantly reduce the risk of ASD or all-cause reoperations compared with ACDF. Similar results were only seen for all-cause reoperations in two-level CDA. Importantly, ASD reoperations occurred within four to five years on average, underscoring that while CDA preserves motion, the risk of subsequent surgery remains. These findings highlight the real-world performance of CDA and may reflect other factors that increase all-cause reoperations, which may have been underreported.
