Patient Language Does Not Impact Need for Manipulation Following Total Knee Arthroplasty

Socioeconomic factors have been associated with an increased need for manipulation under anesthesia (MUA) following total knee arthroplasty (TKA). The purpose of this study was to compare the rate of MUA and range of motion (ROM) following primary TKA in English and non-English-speaking patients. The authors conducted a retrospective cohort study of all primary TKAs performed at their institution between 2010 and 2017. A total of 1,099 English-speaking and 163 non-English-speaking patients were included. There was no significant difference in rate of MUA (3.5 vs. 4.9%, p = 0.392) or postoperative ROM (102.2 vs. 100°, p = 0.142) between English and non-English-speaking patients. Younger age (p = 0.001) and female sex (p = 0.005), but not patient language, were associated with need for MUA. Patient language does not appear to impact the rate of MUA or ROM following TKA.
