The purpose of this study was to evaluate the mid-term clinical and radiological results in patients who were managed by double metal augmentations in proximal tibial uncontained bony defects undergoing primary or revision total knee arthroplasty We performed double metal augmentations in proximal tibial uncontained bony defects undergoing total knee arthroplasty. Out of total 14 patients, 8 patients (4 priamry arthroplasty, 4 revision arthroplasty), mean 61.3 (50–80) years, were available for review at least 5 years follow up. The average follow up period was 86.3(60–99) months. Range of motion, American Knee Society Score were evaluated pre- and postoperatively as a clinical values. Another clinical assessments undertaken at the final reviews, Western Ontario and McMaster Universities osteoarthritis index (WOMAC), Oxford knee score (OKS), Short Form-36 (SF-36), Lower extremity functional scale (LEFS), and Lower extremity activity scale (LEAS) were checked. Radiological results, involving presence of radiolucent lines (RLLs) > 1mm in width, and osteolysis at the block-cement-bone interface were taken under fluoroscopic images at postoperatively and annually thereafter.Introduction
