Abstract：Objective:To analyze the efficacy of arthroscopic treatment for post-traumatic patellar dislocation under wide awake local anesthesia no tourniquet(WALANT)technology,and to explore its effectiveness and safety in clinical application.Methods:A retrospective analysis was conducted on 31 patients with traumatic patellar dislocation who underwent arthroscopic treatment under WALANT anesthesia in Beijing Huimin Hospital from October 2013 to October 2021.Arthroscopic treatment included medial patellar retinacular tightening and lateral release.Hinged knee brace immobilization and rehabilitation training were implemented,and outcomes were assessed with AKS and Kujala scores.Results:6 months after surgery,the follow-up results showed that there were significant improvements in the J-sign and patellar apprehension test(x2=27.011,P＜0.05),and both AKS and Kujala scores increased significantly compared with preoperative levels(t=40.322,51.272;P＜0.05),indicating a marked improvement in postoperative function.The use of WALANT anesthesia reduced anesthesia-related complications and improved the turnover efficiency of the operating room.Conclusion:WALANT combined with arthroscopy for the treatment of post-traumatic patellar dislocation is an effective treatment method,which can significantly improve the function and stability of the patient's knee joint.It has the advantages of less trauma and faster recovery.
