Case:
A 63-year-old woman with 46-year-old bilateral cemented total knee arthroplasty (TKA) presented to our clinic for routine evaluation. She was diagnosed with idiopathic juvenile arthritis at the age of 17. Radiographically she had well-fixed implants bilaterally without bone-cement lucency. She is ambulating without a limp, pain, or an assistance aid.
Conclusion:
We report TKA implants that lasted for 46 years. Literature suggests that most TKAs can last up to 20 to 25 years, but there are few reports that document implant survivorship longer than that. Our report demonstrates the possibility of long survivorship in TKA implants.
