This handsome volume contains the results of part of a large research project on arthritis sponsored by the Commonwealth Fund, the Massachusetts Department of Public Health and the Robert W. Lovett Memorial Fundation. The original work deals with changes in the knee joint at various ages, but the volume really is a comprehensive treatise on "degenerative" arthritis. The interesting point is brought out that after the second decade degenerative changes in the knee joint become common. There are a full bibliography, beautiful plates and an adequate index.
