—Haxton600 reviews the literature dealing with the function of the patella. Experimental work shows that the patella improves the efficiency of knee extension in the more extended positions by holding the patellar tendon away from the axis and thereby increasing the extending movement of the pull of the quadriceps. Haxton, noting that patellectomy impairs the efficiency of the extensor apparatus, believes that the operation should be avoided if possible but believes it to be indicated in inflammatory and neoplastic diseases of bone and in osteoarthritis when this is confined to the patellofemoral articulation.Efskind601 discusses the absorptive function of the synovial membrane. Intra-articular injections of "perabrodil" (iodopyrin injection) were administered in doses of 15 cc., and absorption was controlled roentgenologically. Indigo carmine was administered in doses of 25 cc. of 2 per cent solution, and its concentration in the blood and urine was noted. A
