RESUMO
Total knee arthroplasty (TKA) for preservation of ambulation is indicated in young adults with juvenile rheumatoid arthritis (JRA). The bony deformities of JRA require special measures to adequately seat the prosthesis. Thirteen patients with 25 knee arthroplasties were followed an average of 61 months. Prior surgical operations did not affect the outcome of this procedure. A 55% reduction in pain plus an average 30-point gain on Jergesen's functional assessment scale reflected the overall improvement attributable to TKA. To date, no revisions, infections, or loosenings have occurred in this series of patients.

The development of human digital flexor and extensor tendons from 40 days to 112 days of gestation is described. The differentiation of the cell, the formation of collagen fibrils, and their organization into a relatively complex tendon organ are described. This word was supported by a grant from the Graduate Research Fund of the University of Washington. (Materials were obtained from the laboratory for human embryos which is supported by N.I.H. Grant no. HD00836.) We would like to thank Mrs Bea Watts for secretarial assistance.
