Patient expectation and satisfaction in revision total hip arthroplasty

Sixty-six consecutive revision total hip arthroplasty patients were asked about their expectations regarding future pain and walking ability. Expectations were high, regardless of background factors: 92% expected to have much less pain, and 82% expected the same walking ability as after the primary arthroplasty or a much improved walking ability. Of the patients, 56% stated a non-surgeon-related origin of expectations, 7% were uncertain, and 37% said expectations derived from the surgeon. At 1 year, Harris hip score had increased from a median 45 to 77 points, but only 69% and 55% said that their expectations had been fulfilled to a very large or rather large extent regarding pain and walking ability. The only predictor of fulfilled expectations was absence of complications (odds ratio, 4.8; 95% confidence interval, 1.1-20.8). Patient satisfaction was only moderate; 63% were very or rather satisfied with a moderate correlation (0.46-0.47) between satisfaction and fulfilled expectations. Patients with a poor preoperative hip condition generally were more satisfied (odds ratio, 5.0; 95% confidence interval, 1.4-17.9), and the most important reason probably was an improved walking ability (r = 0.64). Patient dissatisfaction may originate from unrealistic expectations. At preoperative consultation, it is recommended that the surgeon discuss the revision patient's expectations, especially regarding future walking ability, and inform the patient about the fundamental prognostic differences between revision and primary hip arthroplasty.
