Longest Known Follow-up of a Hip Arthroplasty: The Last Chapter of a 65-Year Long Story.

INTRODUCTION: The Smith-Petersen vitallium mold arthroplasty was a real landmark in arthroplasty surgery as this was the first technique which produced predictable and satisfactory results.

CASE REPORT: We present the longest known follow-up of any hip arthroplasty in literature. The arthroplasty was performed in 1949 in London on a 30-years-old female patient with congenital hip dysplasia, and it was revised in 2014 after 65 years.

CONCLUSION: Total hip arthroplasties nowadays give better functional results, but the fact that the patient got 65 years of the relatively good function is noteworthy and is a tribute to Dr. Marius Nygaard Smith-Petersen.
