No. Establishing a claim with Stryker (or any metal-on-metal hip manufacturer including DePuy) is not required by law in order to recovery monetary damages. The claims handling process is usually very much skewed in favor of the company simply due to the fact that the manufacturer is entitled to set up the terms of the process.
In some cases, individuals have established claims with Stryker under the premise that the company would pay for some of their medical expenses. While this may appear to be a short-term help to the individual, most medical payments are offset from the compensation that a person would normally be entitled to. Put another way, most people are more likely to receive far more money for their injuries through a formal litigation process than through an informal claims evaluation system.
