January 2016 tore meniscus in left knee. Had a X-ray and MRI that showed a meniscus tear and little too no arthritis. March 2016 had meniscus surgery. Come June 2016 still having pain. Me and My workers comp nurse requested a MRI. It showed that I had grade 2 and 3 arthritis plus a large spur on the inside of left knee. He recommended having Synvisc shots. After the Synvisc shots. I went through the functional capacity evaluation. I passed all test at 100%. I was able to go back to work at full duty with him giving me a MMI of 10%.
Which to come to find out was very low. I received a permanent partial disability benefit In March 2017. I continued to have a lot of issues went back several times they tried different Band-Aids. April 2019 went different doctor had another x-ray which showed grade 4 arthritis bone on bone and big Spurs on inside and outside of the knee. Next step was full knee replacement surgery was scheduled for May 24th. They put me back out of work until surgery. I started receiving TTD benefits which they said had to be the same as 2016 since it was under the same claim. Even though I was making more money now. Surgery went well. The doctor let me go back to work 8/30/2019 to see how I do. I have been doing great no problems. I go back to the doctor on 9/24/2019. I believe he will release me and give me a MMI rating. I know it will be at least 40% rating. Since this will be the second PPD Benefit. I was wondering how it would work this time around? Also what I might need to know before dealing with the insurance adjuster? Thank you in advance for your advice.
