Medial opening wedge high tibial osteotomy with tibial plate fixation in medial compartment osteoarthritis of knee

Abstract

Aim: Prospective evaluation of medial opening wedge high tibial osteotomy with tibial plate fixation for the treatment of medial compartment osteoarthritis of knee.Method: The study included 31 cases of medial compartment osteoarthritis of knee joint of which 18 were males and 13 were females in the age group of 40-60 years. All the osteotomies were fixed with either wedged plate (n=11) or non wedged plate(n=20).For the clinical evaluation of the patients Hospital of Special Surgery (HSS) score, Knee Society score(KSS) and visual analogue score were taken into consideration for clinical evaluation of the patients. Results: The mean preoperative HSS score was 58.4 and objective and functional knee society score was 57.4 and 57.2 respectively. In the last assessments of our cases, mean improvements detected in HSS scores, Objective and functional scores of Knee Society score were 85.8, 87.3, and 87.1, respectively at 6 months follow up post operatively. Visual analogue score was improved from 8 preoperatively to 1.2 post operatively. Complications such as tendinitis (9.6%), hardware irritation (9.6%), delayed union (6.4%), lateral cortex fracture (3.2%) and superficial infection (3.2%). Conclusion: According to our information, there was significant improvement in the functional outcome and was concluded that medial opening wedge high tibial osteotomy with plate fixation is a reliable and effective procedure for medial compartment osteoarthritis of knee joint.
