Stryker warned doctors about the potential risks associated with use of their hip implants two months before the official Stryker Hip Recall. This was in an attempt to downplay the initial fear factor that would arise when the recall was made. The problem associated with these hip implants is that the stem runs deeper into the femur bone of the leg and has a tendency to corrode. The Stryker models have displayed a high failure rate within a short period of time and there are speculations that there are very serious issues associated with the hip implants that were recalled.
