This meta-analysis pooled 28 RCTs comparing endoscopic carpal tunnel release (ECTR) to open carpal tunnel release (OCTR) across 2,320 CTS hands. It is the largest RCT-only meta-analysis on this topic, and the first to stratify outcomes by follow-up interval. The core question: which technique offers better functional recovery and a safer complication profile?
For a working patient with CTS who asks which surgery gets them back to their job fastest, this paper gives you a concrete answer: ECTR returns patients to work roughly 7 days sooner and produces significantly fewer scar complications.
When counseling any patient before carpal tunnel release, transient nerve injury must be part of the ECTR consent conversation. The risk is nearly five times higher than with open release — even though permanent nerve injury rates are equivalent and most transient injuries resolve fully.
For patients whose primary concern is scar tenderness or palmar wound morbidity (a common complaint after standard OCTR), ECTR reduces that risk by 80%. This is the tradeoff: less scar morbidity, more transient nerve risk.
At one year, both techniques produce equivalent symptom relief, function scores, and digital sensation. So the decision hinges on the early recovery period, not long-term outcome. The authors note that subgroup analyses by portal technique (one vs. Two portal) and incision size (mini vs. Standard open) were not possible, which limits how precisely these numbers apply to any specific technical variant.
