Patient characteristics that affect the outcome of total hip arthroplasty: a review

Abstract

Objective

To review the literature regarding patient factors pertinent to the outcome of total hip arthroplasty (THA).

Data sources

MEDLINE from 1966 onward (key words “hip prosthesis” and “treatment outcome”) and literature previously known to the authors and cited in papers from all sources.

Study selection

All identified studies were included provided the methodology permitted assessment of the effect of patient factors and a clear outcome was defined (either prosthesis survival or specific functional outcomes).

Data extraction

The patient factors, methods and outcomes described in each paper were summarized on a data extraction form.

Data synthesis

All data were reviewed by one author. This process was repeated by a second author, and the findings were reviewed by the remaining 2 authors to verify the findings. The best functional outcomes and prosthesis survival rates were reported among patients who were between 45 and 75 years of age, weighed less than 70 kg, had strong social support, had a higher educational level, had better preoperative functional status and had no comorbid disease.

Conclusion

Important research remains to be done to examine the magnitude and interaction of patient factors on the outcome of THA.
