To compare contact stresses between Attune® and PFC Sigma® total knee arthroplasty (TKA) implants in the presence of knee malalignment. Maximum contact stress after finite element analysis were compared during standing, walking, and stair climbing in 0°, 2.5° and 5°varus/valgus knee alignments. The percentage increase in contact stress was highest during walking with PFC Sigma® in 5° varus (238.5%), standing with Attune® in 5° valgus (127.2%), and standing with Attune® in 2.5° valgus (107.8%). The newer Attune® design may be associated with higher maximum contact stresses and increased risk of wear and implant failure. The newer Attune® design may be associated with higher maximum contact stresses and increased risk of wear and implant failure. Roof arc angle (RAA) is determined by measuring angle between a vertical line drawn from center of the acetabulum towards the acetabular dome and a second line drawn from center of acetabulum to the fracture through the acetabulum. Joel and Matta demonstrated that when roof arc angle was less than 45° on Pelvic AP and Judet's views, the fracture line is considered to be passing through the weight-bearing dome and require surgical fixation. The main purpose of the study is to calculate patient-specific angle and width for the better evaluation and management of acetabular fractures. Radiographs of normal hips were retrieved from electronic data and parameters were calculated. Two observers calculated the parameters at two different intervals. Pearson correlation formula was used to find a correlation between groups. Fifty radiographs of 28 patients were reviewed. The mean ag
