In the past, total knee arthroplasty, although very successful, was

only indicated for an elderly population. Recently though, several

papers have been published confirming that total knee arthroplasty is

effective in younger patients. This paper supports the results of

those papers. In our study, 207 total knee arthroplasties were

performed on patients 55 years old and younger using a posterior

cruciate-retaining prosthesis. There was an overall survival rate of

97.6% with an average follow-up of 9.1 years. There were some minor

variations in the outcome of the operation based on diagnosis

(osteoarthritis vs. rheumatoid arthritis). The success also continued

over time with an estimated survival rate of 94.8% at 12 years. Total

knee arthroplasty is an effective operation in patients younger then

55 years old.
