Abstract:[Objective] To compare the clinical outcomes of Masquelet technique versus Ilizarov technique for treatment of infectious tibial bone defects. [Methods] A retrospective study was conducted on 60 patients who received surgical treatment for infectious tibial bone defect in our hospital from August 2017 to August 2020. According to the results of preoperative doctor-patient communication, 35 patients received Masquelet treatment, the induced membrane technique, while the other 25 patients received Ilizarov therapy, the bone transporta- tion. The perioperative, follow-up and imaging documents were compared between the two groups. [Results] All patients in both groups had operations completed smoothly. The Masquelet group proved significantly superior to the Illizarov group in terms of total number of intraop- erative fluoroscopy and incision healing grade (P<0.05) . The early complications were of 3/35 (8.57%) in the Masquelet group, whereas 9/ 25 (36.00%) in the Ilizarov group, which was statistically significant between the two groups (P<0.05) . During follow-up period lasted for (24.54±5.86) months on an average, the Masquelet group resumed walking and full weight-bearing activity significantly earlier than the Ilizarov group (P<0.05) . The VAS score significantly decreased (P<0.05) , while Iowa knee score, Iowa ankle score and SF-36 score signifi- cantly increased in both groups over time (P<0.05) . VAS score in Masquelet group was significantly better than those of Ilizarov group at 6 months after surgery and the latest follow-up (P<0.05) , although there were no significant differences in Iowa knee score, Iowa ankle score and SF-36 score between the two groups at any corresponding time points (P>0.05) . Radiographically, the Masquelet group got healing of the bone defect significantly earlier than the Ilizarov group (P<0.05) . [Conclusion] Both Masquelet technique and Ilizarov technique are ef- fective for treatment of infectious tibial bone defects, by contrast, the Masquelet technique does achieve considerably better clinical results than the Ilizarov technique in this study.
