$52\%$ of patients were not seen for either the knee or elbow.

Work Step by Step

32% of the patients received therapy for the knee. 16% of the patients received therapy for the elbow. To find the percentage that received therapy for either the knee or elbow, we simply add these two percents. $32\%+16\%=48\%$. Since we are looking for the percentage that were not seen for these two ailments, we must subtract this percent from the total, which is $100\%$: $100\%-48\%=52\%$
