Junior Koenig Knee, 65, a retired executive secretary of the Public Health Conference on Records and Statistics, died Wednesday at Georgetown University Hospital. He had leukemia.

Mr. Knee, who was born in Lawton, Okla., earned bachelor's and master's degrees at the University of Oklahoma. He later earned a master's degree in public health at the University of Michigan.

In 1942, he moved to Washington and joined the wartime Office of Price Administration. A year later, he transferred to the National War Labor Board in Chicago.

In 1945, he returned here and joined the National Office of Vital Statistics in the Census Bureau. In 1946, the program was transferred to the Public Health Service.

Mr. Knee's career at the PHS turned around health statistics and records. He was named executive secretary of the Public Health Conference on Health Records and Statistics in 1968 and held that post until he retired in 1973. He was a consultant to the PHS until 1976.

Mr. Knee, who lived in Fairfax, was a coauthor of "Statistics for Comprehensive Health Planning," which was published by the PHS in 1972. He received the Superior Services Award and the Certificate of Merit from the Department of Health, Education and Welfare as well as other awards.

Survivors include his wife, the former Ruth Ella Irelan, whom he married in 1943, of Fairfax.
