Objective  To investigate the effect of pain control nursing on postoperative knee function after knee fracture.

  Methods  A total of 92 patients with knee fracture were randomly selected, and were divided into control group (46 cases) with routine nursing, and study group (46 cases) with strengthened pain control nursing on the basis of the control group by parallel control grouping. The effects of interventions were compared between the two groups.

  Results  Visual Analogue Scale (VAS) scores in the study group were lower than those in the control group at 1, 3 and 5 d after operation (P < 0.05). After intervention, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores and compliance rate of rehabilitation exercise of the study group were higher than those of the control group (P < 0.05). After 6 months of follow-up, the rate of good and excellent knee function was higher than that of the control group (P < 0.05).

  Conclusion  Postoperative pain control nursing for knee fracture can relieve the pain of patients, regulate the psychological states, improve the compliance of rehabilitation exercise, and improve the function of knee joints.
