| Abstract: Background: Varus deformity is predominantly the commonest deformity in candidates for total knee arthroplasty. Obtaining a well positioned and stable prosthetic construct with restoration of the normal mechanical axes of the limb and joint line have been shown to have an important bearing on the final outcome of knee replacement operations. Objectives: The purpose of the current study is to evaluate patients with varus osteoarthritis who are candidates for total knee replacement, their pre-operative planning, methods for bony and soft tissue. Patients & Methods: In the period between may, 2018 and march, 2019, Retrospective-prospective cohort study was conducted involving 18 patients with 18 knees who underwent primary total knee arthroplasty due to severe varus knee deformity osteoarthritis. Results: The average knee society score improved from 24.22 preoperatively to 79.44 postoperatively and improvement of the functional knee score from 24.05 preoperatively to 80.33 postoperatively No sign of component loosening or osteolysis could be identified on the radiograph of final follow-up of all patients. Conclusions: Patients with severe degrees of varus OA are more likely to have medial tibial bone defects and must be reconstructed by either bone grafts or metal augments and in the same time uploading the tibial surface by long stem to distribute part of the load stresses to the diaphysis. | ||||
