Abstract
Objective To explore the effect and safety of arthroscope-guided bone grafting and suture fixation for nonunion of tibia intercondylar eminence fractures.Methods From July 2014 to October 2016,a total of 8 cases with tibia intercondylar eminence fracture nonunion were treated by arthroscope-guided bone grafting and fixation with suture,including 4 of type Ⅱ and 4 of type Ⅲ.Lysholm knee score and Rang of motion of knee were assessed before,3-,6-and 12 months after the surgery.Anterior drawer test (ADT) and Lachman test were used to evaluate knee stability.Loose bodies were observed by X-image.Results All 8 cases accomplished the surgery successfully.Combined meniscus injury were found in 6 cases,including medial meniscus in 2,lateral meniscus in 1 and medial-lateral in 3;Combined articular cartilage lesion was found in 4 cases.During the surgery,autogenous bone grafting was performed in 6 cases and allogenetic bone grafting in 2 cases.Followed-up duration ranged from 12 to 20 months in 7 patients,but loss in 1 case 2 months after the surgery.All knees achieved full extention and 130° in flexion at least.The fracture healing time was 3 months in 6 cases and 4 months in 1 case.There were negative outcomes in 5 cases and positive outcomes in 2 cases in both ADT and Lachman test 6-and 12 months after the surgery,but no patient felt instable.No loose body was observed 12 months after the operation.The average Lysholm knee score of 6-and 12 months after the surgery was 91.4 ± 7.1 and 96.6 ± 4.6 respectively,both were improvedsignificantly than 82.9 ± 7.3 of pre-operation,and the differences were statistically (t =8.042,P ＜ 0.05,and t =9.731,P ＜ 0.05).Conclusion The surgical intervention of arthroscope-guided bone grafting and suture fixation is safe and effective for fracture nonunion of tibia intercondylar eminence.关键词
