Plain-English summary

DePuy Orthopaedics, Inc. is recalling PFC SIGMA Cruciate Retaining (CR) Cemented Femoral devices (Size 5/RT) used during primary total knee arthroplasty. The recall involves two units with Catalog Number 960015 and specific lot numbers 7810268, 7806929, and 7806934.

The devices were found to have an anomalous microstructure, specifically porosity and the presence of blocky carbides within the cobalt chrome part. These defects can decrease the overall fatigue strength of the implant, which could cause the device to fracture under loads that would normally be acceptable.

The affected devices were distributed worldwide, including in the United States (specifically Iowa, California, Kentucky, and Florida) and in Finland, Germany, Sweden, and the Czech Republic. Patients who have received these specific implants should contact their healthcare provider for evaluation.
