STUDY OF OUTCOME OF HIGH TIBIAL OSTEOTOMY ( HTO) ON OSTEOARTHRITIS OF THE KNEE JOINT AT TERTIARY CARE HOSPITAL

Abstract

Introduction: High tibial osteotomy (HTO) has been used for more than 60 years in clinical practice and mainly involves two major techniques: Closed Wedge High tibial osteotomy (CWHTO)and Open Wedge High tibial osteotomy (OWHTO)

Method: HTOs are performed on 40 patients. The average for men and women was 2: 1. The mean age was 57.0 ± 13.1 years, a BMI of 28.04 ± 3.57kg / m² and a correction angle of 11.5 ± 2.78 °. An analogue scale (VAS) was used to assess the severity of pain. The Knee Society Score (KSS) was used to assess the performance and policy of the knee joint. The deteriorating process was assessed according to Kellgren-Lawrence's X-ray section.

Results: One year after operation, significant decrease in VAS scores (from 74.28 ± 11.79 mm to 7.79 ± 6.32mm) and improvement of effective and meaningful KSS scores (from 41.66 ± 11.5mm and 53, 39 ± 11.77mm to 88.51mm) ± 10.86mm and 82.93 ± 6.65mm) were detected. We found the following HTO results: excellent (51%), good (39%) and satisfactory (10%). X-ray signs of progression of the disease were not disclosed one year after surgery. The connection of BMI with the immediate outcome of surgery is revealed. (Spearman coefficient = 00.35 to p <0.05). Incidence of inactivity after HTO was reported to be 5% in our study. Risks of non-verification include a high level of correction in HTO, smoking, and adequate correction.

Conclusion: From this study, we conclude, HTO is a procedure performed to treat knee arthrosis in younger or middle-aged patients. Proper patient selection, appropriate types of osteotomy, and accurate surgical techniques are essential to HTO success.
