Total knee arthroplasty stabilized with autologous bone graft for tibial bone defect correction

Evaluate the functional results obtained with total knee arthroplasty stabilized with autologous bone graft to correct axis deviation with tibial bone failure. A retrospective study with a convenience sample, consisting of fifteen patients operated between February 2015 and June 2019. Data were obtained through analysis of medical records: age, biological gender, affected side, pre- and postoperative radiographs, description of the surgical technique and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire results preoperatively and 6 months after surgery. The average age of the patients was 67 years, majority male (53.3%) and varus deformity (80%). The mean time to release the load was 31 days and all patients were discharged two days after surgery, with no complaints of complications. In the preoperative period, pain and physical function had the highest scores in WOMAC questionnaire. After total knee arthroplasty, there was a significant improvement in the three dimensions of WOMAC, with a reduction of 78.6% in the total score. Total knee arthroplasty stabilized with autologous bone graft to correct axis deviation with tibial bone failure resulted in improvement of symptoms and physical function in most patients evaluated, reducing pain and functional disability due to gonarthrosis.
