Objective To investigate the effect of non-whole-time application of tourniquet in arthroscopy combined with high tibial osteotomy on clinical outcomes. Methods Clinical data of patients who underwent arthroscopic combined tibial high osteotomy in our hospital from June 2018 to January 2022 were retrospectively analyzed, and a total of 72 patients were included in this study according to the inclusion and exclusion criteria, which were divided into 38 cases in the whole time tourniquet application group and 34 cases in the tourniquet application group only in the arthroscopic exploration stage, and the perioperative indicators were recorded and compared between the two groups. Results (1)There was no statistical difference in terms of operative time and hospitalization days (P>0.05). (2)There was no statistical difference in terms of postoperative hemoglobin, hematokrit, drainage volume, blood loss and transfusion rate between the two groups (P>0.05). (3)The non-whole-time tourniquet group had lower pain scores in the early postoperative period and could achieve better range of motion on the third postoperative day (P<0.05). (4)There was less incidence of thigh pain in the non-whole-time tourniquet group (P<0.05), but there was no statistical difference in other complications between the two groups (P>0.05). Conclusions The results suggest that the use of tourniquet only in the stage of arthroscopic exploration will not increase the postoperative blood loss, operation time and hospital stay after high tibial osteotomy. However, it can reduce the pain of knee and tourniquet site in the early postoperative period, which is conducive to the early postoperative functional recovery, and will not increase the incidence of complications.
