Objective:To investigate and assess the systemic functional training in the prevention of lower limb trauma fracture surgery knee stiffness effect. Methods: Select General Hospital of PLA (301 Hospital) traumatic lower extremity Department of orthopedics from 2009 since April admissions of fractures in patients with 126 cases, according to the nursing methods of postoperative patients were divided into experimental group 63 cases and control group 63 cases, control group was given routine nursing after traumatic fracture of lower limb, the experimental group received training rehabilitation care plan and patient in the control group. Postoperative follow-up, the time of 5 months-2 years, two groups of patients were muscle strength, extension and flexion degree and the patients with complications were analyzed statistically, and the comprehensive evaluation of knee joint function recovery of patients. Results:The postoperative knee flexion strength and degree than the control group;experimental group, the complication rate was 15.9%in the control group of patients swelling after seven cases, the complication rate was 28.6%; comprehensive evaluation knee function two groups of patients in the experimental group was 82.5% excellent (52/63), good rate of the control group was 65.1% (41/63);said comparison items were statistically significant differences (x2=12.6, P<0.05). Conclusion: Lower limb trauma fracture surgery rehabilitation for patients with systemic functional training rehabilitation care, joint function recovery is remarkable, scientifically valid methods, should be further promoted.
