We have experienced two patients who developed dysfunction in another joint after TKA. The first case was a 76-year-old woman with bilateral knee osteoarthritis who suffered bilateral femoral neck fractures 6 months after bilateral TKA. The second case was a 71-year-old woman with rheumatoid arthritis who suffered advanced destruction of her left hip joint 16 months after bilateral TKA. These cases suggested problems such as preoperative evaluation, postoperative management, operative order, and operative interval.
