Abstract

Background: Osteoarthritis is more common in females. It is because osteoarthritis in post-menopausal women is associated with higher body weight, higher subcutaneous fat, calcium deficiency and weaker muscles linked to hormonal changes. The purpose of this study was to evaluate the role of high tibial osteotomy fixed with angle stable plate in treatment of osteoarthritis of knee. Material and Methods: In our study 10 cases were operated by modified coventry technique, 10 cases were operated by open wedge osteotomy with non locking plates and bone graft and 104 cases were operated by medial open wedge osteotomy and iliac graft secured by locking plate. In these cases full weight bearing was allowed at 8 week, 6 week and 3rd post operative day respectively. Radiographical analysis include post operatively change in tibio-femoral angle. Mean follow up of these cases was 2 year. Results: In our study thee knee pain and function score were significantly improved (p value <0.001). The average pain score preoperatively was 1 8± 7(the maximum pain score for pain is 50) and post-operatively was 44±5. According to the grading used for functional assessment in knee scores there was definite improvement in the function of cases 122 (98.38%) at 2 yrs. The preoperatively mean functional knee score in of 110 cases (88.7%) cases was 28.86 (the maximum functional knee score is 100) and postoperatively was 70.45. There is correction in tibiofemoral angle (mean preoperative and postoperative tibiofemoral angle was 5.2±1.5 degrees varus and 5.8±1.3 degrees valgus respectively). Conclusion: There was definite improvement in the pain and function of the knee after the correction of the deformity (P value <0.001). The results of high tibial osteotomy in 88.23 percentage knees were rated as excellent. 104 out of these 124 cases were fix by locking plates. 2 cases had poor results due to excessive over correction and associated comorbidities. There is a definite correlation between the postoperative valgus obtained and relief in the pain.
