Abstract
In advanced painful hemophilic arthropathy of the knee (APHAK) and advanced painful osteoarthritis of the knee (APOAK) the last resort is total knee arthroplasty (TKA). However, some patients with APOAK are not satisfied despite a good clinical result. A review the literature on APHAK and APOAK was performed to know their rates of dissatisfaction and their main causes. In APOAK the rate of dissatisfaction ranges between 3 and 28.3%. Causes of dissatisfaction in APOAK are high preoperative body mass index, lack of fulfillment of patient expectations, a low 1-year WOMAC, preoperative pain at rest, a postoperative complication requiring hospital readmission, and a poor preoperative psychological state. Very limited information exists on APAHAK in the literature, but it also shows an increase in patient satisfaction after TKA. However, the results do not reach the same level as in patients with APOAK, due to residual symptoms and impairment of other joints.
