The use of dexamethasone did not increase the risk for wound complications or infections. Each group had one patient who had a periprosthetic joint infection develop (Dexa-Ra group, 0.7% versus Ra group, 0.7%; p > 0.1). There was no difference in the incidence of wound complications between the two groups. The Dexa-Ra group had two patients with inadequate wound healing and the Ra group had three (Dexa-Ra group, 1.5% versus Ra group, 2.2%; p > 0.1) during the first year after TKA. The two patients who had periprosthetic joint infections were treated with débridement, polyethylene component exchange, and antibiotics; at 1 year, the infections had not recurred. All patients in both groups who had inadequate wound healing were treated successfully with conservative management. A power analysis for comparison of wound complication incidence showed that this study (3% in Ra group) had 80% power to detect the difference at a 10% increase of wound complication incidence at an alpha level of 0.05 using a two-sided test. There was no differential loss to followup between groups; eight patients from the Dexa-Ra group (5.9%) and six from the Ra group (4.8%) were unable to return for followup at 1 year (p > 0.1). All patients who did not return for followup at 1 year were contacted by telephone to assess for the presence of periprosthetic joint infection.
