Abstract:Abstract: Objective To study the effect of arthroscopic guided reduction and internal fixation on the fracture of the tibial plateau and the recovery of knee function and quality of life. Methods 104 FTP patients from August 2016 to March 2018 were randomly divided into observation group and control group, 52 cases in each. The observation group underwent knee arthroscopic assisted open reduction and internal fixation, and the control group underwent conventional open reduction and internal fixation. Surgical parameters (incision length, bleeding volume, time of surgery, postoperative drainage and bedtime), bone biochemical parameters (Ca2+, CT, BMP, NBAP) and therapeutic efficacy, knee function Lysholm score, life quality SF-36 score and complications occurrence were compared between the two groups. Results Before treatment, there were no significant differences in bone biochemical parameters, Lysholm scores, and quality of life SF-36 scores between the two groups (P > 0.05). After treatment, the incision length, blood loss, postoperative drainage volume, time to bed, and NBAP were significantly lower in the observation group than in the control group (P < 0.01). The observation time, the Ca2+, CT, BMP and Lysholm scores in the observation group, SF-36 The scores were significantly higher than the control group (P < 0.01). The effective rate of treatment in the observation group was 90.38%, which was significantly higher than that in the control group (80.77%) (P < 0.01). The complication rate in the observation group was 11.54%, which was significantly lower than that in the control group (28.84%) (χ2 = 4.69, P = 0.002). Conclusion Arthroscopic guided reduction and internal fixation can significantly increase the efficacy of patients with tibial plateau fractures, promote knee function recovery, improve bone metabolic markers in patients, and improve the patient’s quality of life.
