Introduction: Revision hip arthroplasty is associated with less favorable short and
long term results than primary total hip arthroplasty. In this context, we evaluated
quality-of-life and patient satisfaction 4 years after implantation, comparing revision
THA versus primary THA. Methods: The study included patients who underwent
primary (n = 248) or revision THA (n = 84) at the Universitary Clinic of Orthopaedics
and Traumatology, Tg. Mures between 2002 - 2004. 4 years postoperatively, quality
of life was measured by Harris Hip Score, WOMAC Index. Patient satisfaction,
assessed on a Visual Analog Scale (VAS) from 1 to 10. Results: Patients undergoing
a revision were older (76 years versus 61 years), more often obese (BMI: 36%
versus 18%), and presented more medical and Orthopaedic comorbidities. Four
years after surgery, 202 patients with primary THA and 64 with revisions were
available for follow-up. Quality of life and satisfaction were significantly lower after
revision (Harris Hip Score 74,2 vs 91,4; WOMAC pain 64.7 vs 78.3; satisfaction 7.1
vs 9.1). Adjustment for the preoperative status attenuated these differences which
nevertheless remained significant. The influence of age, comorbidities, and
preoperative function on 4-year outcomes did not substantially differ for the 2
intervention groups. Obesity was associated with a stronger negative effect on
revision surgery. Discussion: Functional outcome and satisfaction were lower after
revision THA than after primary THA. Conclusion: Considering the risks and benefits
of revision surgery, it is important to recognize not only the surgical factors but also
the characteristic features of the patients.
