Article abstract: Introduction & Objective: Osteotomy is the classic operation for the treatment of patients with primary degenerative osteoarthritis and for the correction of their deformity. Considering the existence of different methods for their treatment, preoperational assessment and its comparison with post operation measures has a significant role in determining the prosperity of surgery and patient's follow up. The aim of this study is to investigate the radiologic changes in these patients.
Materials & Methods: In a case series study from 2004 to 2010 in Shafa Yahyaeeian hospital (a referral hospital in Tehran, Iran) patients with osteoarthritis who had signs and symptoms of medial compartment of knee and varus deformity underwent open wedge tibial osteotomy. Using anteroposterior and lateral radiography in standing position, the limbs alignment before and after the operation were investigated.
Results: Totally 29 patients (36 knees) were investigated. Fourteen patients were females. All of them were younger than 50 years with mean ± SD (27.64± 10.88). The follow up time was (4.33 ±1.7). Tibial slope and grade DJD increased after operation. Insall-salvati and Blackburn-peel indices had no change. Two cases were not corrected completely, due to simultaneous deformity in the distal of femur. Three cases had fracture of lateral plateau due to some technical problems during operation. They had little dislocation and were treated completely in next follow up by using nonsurgical treatment.
Conclusions: Open wedge osteotomy can have good results in the radiologic finding and deformity correction of patients with primary degenerative osteoarthritis.
