Comparison of Postoperative Pain and Application Effect of High Tibial Osteotomy and Total Knee Replacement in Patients with Knee Arthritis

Abstract

Objective: To investigate the effects of high tibial osteotomy (HTO) and total knee replacement (TKR) on postoperative pain of patients with knee arthritis. Methods: From February 2017 to March 2019, 72 patients with knee arthritis in our unit were collected for the experiment. Patients in the control group (CG, 35 cases) were treated with HTO, and research group (RG, 37 cases) were treated with TKR. Clinical efficacy, Visual Analogue Scale (VAS) score, Knee Society Score (KSS), and Hospital for Special Surgery (HSS) knee rating score of the two groups of patients were observed. Intraoperative blood loss, operative time and hospitalization expenses were observed, as well as the effect of knee joint recovery after operation.Results: In terms of overall effective rate, RG was superior to CG (p < 0.05). VAS score of RG was notably lower at 1 week and 2 weeks after operation than that in CG (p < 0.05). KSS of RG was evidently higher than that of CG (p < 0.05). HSS score of RG was notably higher than that of CG after operation (p < 0.05). The intraoperative blood loss and operative time in RG were notably better than those in CG (p < 0.05). The effects of knee joint recovery in RG was considerably better than that in CG (p < 0.05). Conclusion: TKR has a better clinical effect on elderly patients, which can reduce postoperative pain, intraoperative blood loss and operative time, and improve the recovery effect of knee joint.
