Unplanned return to the operating room after arthroscopic procedures: a need to consider 12months after the initial surgery.

Abstract

The purpose of this study was to report the proportion and cause of unplanned revision surgery rates within 1year following arthroscopic procedures. Our hypothesis was that there is a significant rate of unplanned returns (URs) occurring between 3 and 12months after the initial procedure and that causes of revision are different when considering the delay after the index surgery. Among 4142 consecutive patients who underwent an arthroscopic procedure in a single department of orthopedics and traumatology, patients undergoing revision surgery for any reasons directly related to the primary procedure were included. Cause for revision, surgical site, delay from index procedure, and number of revisions were screened. Seventy-eight patients underwent 97 revision surgeries (2.3%) for reasons directly related to the primary procedure. Most revision surgeries were performed after month 3 following index surgery (59 patients, 60.8%). Mean time to revision surgery was 5.3 ± 4.3months (range 0-365days). Usual early-onset (< 3months) reasons for unplanned revision were surgical site infection (17 patients, 0.41%), wound-healing defect (12 patients, 0.29%), and hemorrhagic complication (7 patients, 0.17%). Reasons for delayed unplanned revision (> 3months) were index procedure failure (21 patients, 0.51%), stiffness (18 patients, 0.43%), and removal of hardware (16 patients, 0.41%). Reasons for return to the operating room (OR) are different depending on the timepoint from index procedure. Patients should receive relevant information accordingly when scheduling any arthroscopic procedure, including up to 1-year potential complications. Prognostic study, Case series, Level IV.
