Oxford Knee Score could identify variation in post-TKA patient satisfaction

The Oxford Knee Score helped investigators identify patient satisfaction after total knee arthroplasty at 12 months and 24 months postoperatively based on these study results.
The investigators studied 608 patients who underwent elective primary total knee arthroplasty (TKA) between 2003 and 2007 and completed a preoperative Oxford Knee Score (OKS) questionnaire about knee pain and function during the most recent 4-week period. They then readministered the OKS questionnaire at 12 months and 24 months following surgery. In all, 365 patients completed the three questionnaires about their satisfaction with TKA.
The results showed 83.8% of patients were satisfied with TKA at both follow-up time points and that there were similar responses concerning increased function, decreased pain and decreased pain medication. Furthermore, the reported patient satisfaction was correlated with an increase in overall function and with decreased pain.
Researchers found that men had a higher OKS at 12 months and 24 months, as did patients in the higher baseline OKS tertiles and patients who had a preoperative expectation of no pain. Direct comparisons of responses at the 12 month and 24 month follow-up showed there were similar median values for the follow-up OKS, the change in OKS and the percentage of potential change. The median OKS increased from 20 points at baseline to 38 points at 12 months among satisfied patients compared to an increase of 18 points at baseline to 25 points at 12 months among unsatisfied patients. The median OKS also increased from 20 points at baseline to 39 points at 24 months among satisfied patients compared to an increase from 19 points at baseline to 26 points at 24 months among unsatisfied patients, according to the results. – by Casey Tingle
