A transverse section through such a thickened capsule is shownin Fig. Fig. 3.—Thickened capsule of knee joint; case of resection of : a, Outer layer of normal fibrous tissue; &, Bundles of fibroustissue inlaid with lymphoid tissue; c, Inner layer of adenoid tissue con-taining numerous tubercles; d, Tubercles without giant cells; e, Tuber-cles with giant cells; /, Vessels. The following are the microscopic features: a, An outerlayer of normal fibrillar connective tissue of the fibrous capsuleof the knee joint. Inside of this, at 6, two obliquely-cutbundles of fibrous tissue, partially transformed into adenomatoidtissue. Finally the thickest inner layer, c, consists of adeno-matoid tissue, with a large number of disseminated miliary tu-bercles, some of which contain a large giant cell, e, whileothers, d, d, tZ, have a center consisting of the giant cell reticu-lum without giant cells, but all of them are surrounded by adarker ring of the lymphoid reticulum.
