Ltd.10.26689/BAS.v4i4.15273ArticleComparative Analysis of Clinical Efficacy Between One-Stage and Staged Reconstruction for Repairing Multiple Ligament Knee Injuries under Arthroscopyhttps://artdesignp.com/journal/BAS/4/4/10.26689/BAS.v4i4.15273RenXingkuan,LiShuai,ZhangGuangxiang,DaiYunyun,TangShaoxiong,ZhongYuke,ZhuBaohong2026442026-08-31Objective: To compare the postoperative functional recovery, range of motion, and complication rates of one-stage and staged reconstruction for repairing multiple ligament knee injuries (MLKI) under arthroscopy, providing evidence-based guidance for clinical treatment selection. Methods: A total of 60 patients with KD-ⅢM type MLKI admitted to the Orthopedics Department of Ankang Hospital of Traditional Chinese Medicine from January 2024 to January 2026 were selected and randomly divided into an observation group (one-stage reconstruction, 30 cases) and a control group (staged reconstruction, 30 cases) using a random number table method. Both groups utilized autologous semitendinosus, gracilis, and peroneus longus tendons as grafts, with surgeries performed by the same surgical team. Lysholm knee function scores, IKDC subjective scores, and knee flexion-extension range of motion were recorded preoperatively and at 12 weeks, 6 months, and 12 months postoperatively. Results: At 12 weeks postoperatively, the observation group demonstrated higher Lysholm scores, IKDC subjective scores, and knee flexion-extension range of motion compared to the control group (all P < 0.05). Conclusion: Arthroscopic one-stage reconstruction enables faster recovery of early knee joint function and reduces financial and psychological burdens on patients. Staged reconstruction carries a lower risk of postoperative joint adhesion and stiffness, with no significant difference in long-term knee function recovery compared to one-stage surgery. Clinical surgical plans can be individualized based on patient age, injury severity, and rehabilitation compliance.Multiple ligament knee injuries, Arthroscopy, One-stage reconstruction, Staged reconstruction
