rheumatoid arthritis.

Forty-seven cemented total knee arthroplasties in 32 patients with

rheumatoid arthritis who were 55 years or younger (average, 43) were

followed until death or a minimum of 15 years. The average follow-up was 18

years. There were 6 revisions; 5 of 6 revisions had severe polyethylene wear

and osteolysis. All revisions occurred after 17 years (range, 17-23). Three

of these had fracture of the tibial component associated with polyethylene

wear through; the remaining 2 had loose tibial and femoral components. One

patient sustained a distal femoral periprosthetic fracture requiring

revision of the total knee. Cemented total knee arthroplasty in the young

patient with rheumatoid arthritis is reliable and durable at an average 18

years of follow-up with an estimated survivorship of 100% at 15 years and

93.7% at 20 years.
