Remaining pain after total knee arthroplasty (TKA) is a common observation in about 20% of postoperative patients; wherein about 60% of these knees require early revision surgery within five years. Obvious causes of this pain could be identifiedsimply with clinical examinations and standard radiographs. However, unexplained painful TKA still remains a challenge forthe surgeon. The management should include a multidisciplinary approach to the patient`s pain as well as addressing theunderlying etiology. There are a number of extrinsic (tendinopathy, hip, ankle, spine, CRPS and so on) and intrinsic (infection,instability, malalignment, wear and so on) causes of painful knee replacement. On average, diagnosis takes more than 12months and patients become very dissatisfied and some of them even acquire psychological problems. Hence, a systematicdiagnostic algorithm might be helpful. This review article aims to act as a guide to the evaluation of patients with painful TKAdescribed in 10 different steps. Furthermore, the preliminary results of a series of 100 consecutive cases will be discussed.Revision surgery was performed only in those cases with clear failure mechanism.
