on the job injury right to claim under WA workers compensation law

In addition to checking this out with a local attorney who specializes in worker compensation law, you will also want to contact the WA state department of labor and/or the WA state Worker Compensation Commission. While information concerning how various injuries are rated for purposes of compensation are available, it will likely only provide you with a range. Good luck to you and best regards, Rob Fortgang

It depends on both the date of injury and what part of the leg the rating is based on. The schedule of benefits changes every July 1 due to a cost of living increase. Ratings are done based on either the American Medical Association Guidelines. For instance, a December 2007 injury with 100% disability of the leg at the knee joint (with short thigh stump) is $101,628.49. The 50% disabled knee rating you asked about would likely need to be translated into a rating for the whole leg. Then that percentage can be taken from the 100% figure above.
