Finite element analysis was performed using 3-dimensional model to analyze the biomechanical effects on the hip and knee joint after unilateral total hip arthroplasty. Clinical studies have reported that hip and knee osteoarthritis (OA) often occurred on the contralateral (non-implanted) side after unilateral total hip arthroplasty (THA). Both local and systemic stress-shielding occur on the lower extremities when used various material property of THA implants. It demonstrated that the force reaction with unilateral THA surgery was carried more in ipsilateral side (implanted side) than contralateral side, while total deformation was higher in contralateral side and the maximum stress value was higher on contralateral side of femoral condyles than ipsilateral side.
