Metacarpophalangeal arthroplasty in rheumatoid arthritis: what determines satisfaction with surgery?
OBJECTIVE
In patients with rheumatoid arthritis (RA), it is unclear what determines satisfaction with metacarpophalangeal (MCP) joint replacement surgery. Previous studies have focused primarily on objective outcomes, such as range of motion (ROM) or strength, although some subjective measures have been examined. We investigate which outcomes most strongly correlate with patient satisfaction.


METHODS
We assembled a retrospective cohort of 26 RA patients who received a total of 160 MCP silastic spacer implants. Patients answered a telephone survey, and 18/26 patients were examined. The strength of association between specific outcome variables and patient satisfaction with surgery was measured using Spearman correlations.


RESULTS
Patients had a mean age of 64.8 years and 77% were female. The mean time since surgery was 5.5 years. The strongest determinant of patient satisfaction was postoperative hand appearance (Spearman r > or = 0.60). Pain was also highly correlated with satisfaction with surgery (Spearman r > or = 0.46). Ability to perform activities of daily living and portions of the Jebsen Hand Function Test were moderately correlated with patient satisfaction. Most other measures of hand strength and ROM showed only minimal correlation with patients' overall satisfaction with surgery.


CONCLUSIONS
Overall satisfaction with silastic spacer surgery in this cohort of RA patients was most influenced by postoperative hand appearance and by pain. While objective measures of surgical outcomes are valuable reflections of technical success, they are not important determinants of patient satisfaction. The criteria used to assess MCP arthroplasty results should be revised to better capture the outcomes that appear to matter most to patients.
