After Total Ankle Arthroplasty, When Does Bone Perfusion and Metabolic Activity at the Bone-Implant Interface Normalize? A PET/CT Study

Back to course

Video Transcription

Video Summary

The video discusses a study on bone perfusion and metabolic activity at the bone implant interface after total ankle arthroplasty. The study used PET-CT with 18-sodium fluoride to assess tracer uptake in asymptomatic patients at different time intervals after surgery. The results showed that periprosthetic bone blood flow and bone turnover remained elevated up to 24 months post-surgery, with no significant decreases in values between 6 and 24 months. Therefore, interpretations of these results should be cautious within two years of total ankle replacement, and patient symptoms should be considered. The study used modern fixed-bearing total ankle replacements. No credits were mentioned in the video.
