## TL;DR

A tennis player experienced two implant failures in his wrist joint after surgery, with the implant making a squeaking noise before replacement.

## Contribution

This is the first reported case of Pyrocardan implant failure and squeaking during physical activity.

## Key findings

- The Pyrocardan implant broke twice during tennis training.
- Squeaking occurred after the first implant failure and stopped after revision.
- Implant revision resolved the squeaking issue.

## Abstract

A healthy middle-aged man was treated for isolated scaphotrapeziotrapezoid joint osteoarthritis with implant arthroplasty using a Pyrocardan implant. We report implant breakage twice during tennis training, and the debut of squeaking after the first failure. The implant was revised and replaced both times. Revision of the implant resolved the squeaking. To our knowledge, this is the first report of a type of complication with this implant, indicating potential limitations for its future use.
