AbstractIschial tuberosity cyst is a common disease, and the conventional incision procedure is associated with several disadvantages, leading to unsatisfactory therapeutic outcomes. The aim of the study was to evaluate the clinical outcomes of arthroscopic treatment for ischial tuberosity cyst and compared it with conventional incision surgery.The clinical data of 57 patients with ischial tuberosity cyst from May 2016 to September 2018 were retrospectively analyzed. According to the inclusion and exclusion criteria, a total of 49 patients were included. Of these patients, 24 patients received arthroscopic procedure (N = 24) and 25 patients received conventional incision procedure (N = 25). The operation time, intraoperative blood loss, postoperative drainage, postoperative hospital stay, and postoperative complications were compared between the 2 groups. Visual analogue scale scores was used to evaluate pain at 1 day, 1 week, and 1 month after the surgery.All 49 patients were followed up for (11.3 ± 3.3) months. All patients in the arthroscopy group achieved phase I healing while 3 patients in conventional incision group developed complications. The operation time, intraoperative blood loss, postoperative drainage, and hospital stay in the arthroscopy group were (54.7 ± 7.7) minutes, (20.8 ± 3.5) mL, (20.3 ± 5.6) mL, and (2.8 ± 0.6) days, and were significantly better than those of (71.8 ± 8.8) minutes, (67.3 ± 12.0) mL, (103.6 ± 20.3) mL, and (7.8 ± 2.9) days in the conventional incision group, respectively. In the arthroscopy group, the visual analogue scale scores at 1 day, 1 week, and 1 month after the surgery [(2.6 ± 0.7), (0.5 ± 0.6), (0.3 ± 0.5) points] were significantly lower than those in the conventional incision group [(6.0 ± 0.7), (3.0 ± 1.0), and (1.1 ± 1.0) points], and the differences were statistically significant (P < .05). Finally, no significant difference was observed in the incidence of postoperative complications between the 2 groups (P > .05).In the treatment of ischial tuberosity cysts, arthroscopy has advantages of minimal invasion, less blood loss during perioperative period, milder postoperative pain, and rapid recovery when compared with conventional incision surgery.Copyright © 2022 the Author(s).
