RESUMO
Objective To compare the value of arthroscopic assisted percutaneous internal fixation and open reduction and internal fixation in treatment of tibial plateau fracture.Methods The clinical data of 180 patients of tibial plateau fracture were analyzed retrospectively,including 112 patients of type Ⅱ fracture (group A) and 68 patients of type Ⅲ fracture (group B).The patients in group A and group B were divided into group A1 (56 patients),A2 (56 patients),B 1 (34 patients),B2 (34 patients) respectively according to the odd number and even number of admission date.The patients in group A1 and B1 received open reduction and internal fixation and the patients in group A2 and B2 received arthroscopic assisted percutaneous internal fixation.The postoperative functional recovery was compared and evaluated between the same type of tibial plateau fractures under different treatments.Results In group A1:the postoperative functional recovery,the excellent was 12 patients,the good was 26 patients,the middle good was 12 patients,the bad was 6 patients.The rate of the excellent and the good was 67.9％ (38/56).In group A2:the postoperative functional recovery,the excellent was 19 patients,the good was 34 patients,the middle good was 3 patients.The rate of the excellent and the good was 94.6％(53/56).The rate of the excellent and the good between group A1 and group A2 had significant difference (P ＜ 0.01).After operation for 6 months,the HSS scores of knee joint and degree of flex and extend in group A1 and A2 had significant difference [(73.21 ± 8.32) scores vs.(85.58 ±9.89) scores,(35.6 ±6.6)° vs.(55.1 ±8.8)°] (P ＜0.01).In group B1:the postoperative functional recovery,the excellent was 8 patients,the good was 16 patients,the middle good was 7 patients,the bad was 3 patiens.The rate of the excellent and the good was 70.6％(24/34).In group B2:the postoperative functional recovery,the excellent was 12 patients,the good was 21 patients,the middle good was 1 patient.The rate of the excellent and the good was 97.1％(33/34).The rate of the excellent and the good between group B1 and group B2 had significant difference(P ＜ 0.01).After operation for 6 months,the HSS scores of knee joint and degree of flex and extend in group B1 and B2 had significant difference [(75.32 ± 7.99) scores vs.(86.41 ±10.21) scores,(33.9 ±7.2)° vs.(56.6 ± 10.5)°](P＜0.01).Conclusions The efficacy of arthroscopic assisted percutaneous internal fixation is better than open reduction and internal fixation either in type Ⅱ fracture or in type Ⅲ fracture.This method is mini-invasive and is worthy to spread.
