Ten-year survival analysis of the PFC total knee arthroplasty-a

surgeon's first 99 replacements.

Ninety-seven patients with 99 total knee arthroplasties were operated

on by a surgeon in the first 3 years of his surgical career. Complete

survival data were available for all 99 knees. The cases were reviewed

at a minimum of 10 years after their initial operation, but as 37

patients had died before reaching 10 years, the average follow-up was

8 years 8 months with a maximum of 12 years 4 months. Ninety-one

patients had osteoarthritis, five had rheumatoid arthritis, and three

had juvenile chronic arthritis. No patients were lost to follow-up.

Four required revision. The 10-year survival rate, using revision for

all causes as an end-point, was 94.96%. The survival rate for aseptic

loosening was 97.04%. The survival rate for loose joints that had not

been revised was 94.13%. Three of the four revisions occurred in the

first 6 patients operated upon, suggesting there may be a learning

curve for surgeons at this stage in their career.
