Although both men and women with osteoarthritis had poor estimates of total knee arthroplasty outcomes, women experienced more accurate total knee arthroplasty outcome expectations and greater decision readiness compared with men, according to study results.

Researchers had patients with moderate-to-severe knee osteoarthritis view a video about knee osteoarthritis treatment options, including total knee arthroplasty (TKA). Patients also received a personalized arthritis report. The researchers used an adapted version of the WOMAC to assess pain and physical function expectations following TKA before and after the intervention and compared these scores to an age- and gender-adjusted means for a cohort of patients who had undergone TKA.

Results showed both men and women had poorer expectations about postoperative pain and physical outcomes at baseline vs. observed outcomes of the comparator group. However, the researchers found an improvement in women’s mean age-adjusted expectations about post-TKA pain outcomes following the intervention, whereas men did not have a significant change in their pain expectations. Women were also closer to observed post-TKA outcomes, according to study results.

Similarly, women demonstrated a significant improvement in decision readiness, whereas men did not. After the intervention, both men and women had less decision conflict, according to the researchers. – by Casey Tingle
