| Objective. Determine the cross-sectional relationship between the presence and severity of medial tibiofemoral (TF) osteoarthritis (OA) symptoms and toe out angle during walking. Methods. Among participants in the Multicenter Osteoarthritis Study (MOST), we selected knees with radiographic medial TF OA. We inquired about knee pain presence and severity and assessed toe out angle at normal and fast walking speeds using an instrumented walkway. Linear regression with generalized estimating equations compared mean toe out angle between knees with and without pain while adjusting for covariates. Results. 269 participants contributed 374 knees. Mean toe out angle at normal and fast walking speeds (respectively) was smaller among knees with current (p=0.09, p=0.05), frequent (p=0.33, p=0.14), and more severe pain (p=0.36, p=0.12), although the differences were not statistically significant. Conclusion. Among persons with medial TF OA, non-significant trends suggest that knees with symptoms may have reduced toe out angles during walking. |
