**Employee:** William Wilson
**Injury No.:** 17-085134
Mr. Wilson testified to his health history prior to November 8, 2017, as follows:
In 1979, Mr. Wilson injured his right knee while playing football and had ligaments in his right knee repaired surgically. Mr. Wilson described the right knee as unstable thereafter, but he was able to work construction. On August 5, 1987, Mr. Wilson fell off of a second story roof, a distance of about 16 feet, while hanging a long piece of guttering. Mr. Wilson underwent a right knee construction with Dr. Ryan on November 3, 1987. Because the knee remained weak and swollen, he had another right knee construction performed by Dr. Pat Smith on March 31, 1988. The right knee continued to be unstable and painful; Mr. Wilson had a right knee replacement performed on October 4, 2011, by Dr. Michael Snyder. Mr. Wilson said that his pain improved from a level nine out of ten before the surgery to a level six out of ten post surgery, but that the right knee continued to feel unstable and loose, with popping and clicking. Mr. Wilson has had difficulty maneuvering on stairs and uneven ground since the last surgery on the right knee in 2011.
On August 4, 1992, Mr. Wilson "blew out" his left knee while pouring concrete for Hagemeyer Concrete. On October 9, 1992, Dr. Cameron cleaned out cartilage and ligament in the left knee. Mr. Wilson continued to have trouble with the left knee and had a second surgery on the left knee performed by Dr. Pat Smith in February of 1994. Mr. Wilson had a left knee replacement with Dr. Snyder shortly after the right knee replacement in 2011. The left knee replacement resulted in a staph infection, causing Mr. Wilson to need two additional left knee replacements performed by Dr. Snyder in 2011. On January 11, 2012, Mr. Wilson had surgery with Dr. Alito to remove the prosthetic in the left knee; on March 21, 2012, a new artificial joint was placed in the left knee along with skin grafting. Mr. Wilson had a ninth surgery on the left knee in 2012 to remove an infected area of the knee.
In 1999, Mr. Wilson was initially diagnosed with coronary artery disease which caused impaired blood flow. Mr. Wilson had two heart attacks and eight stents placed in his arteries between 2000 and November of 2017. Mr. Wilson's cardiovascular issues cause him to be short of breath, unable to walk farther than about 150 feet and to suffer from chest pain, particularly while lying down, eating, and walking.
On November 8, 2017, while working for Jack's, Mr. Wilson was getting ready to unload pallets when the higher of two stacked pallets fell on him, the brunt of the weight on his right foot. Mr. Wilson said that four bones were broken and that he had surgery with Dr. McAleer, who put the broken bone back together with screws. Mr. Wilson said that his right foot never healed and that his care was transferred to Dr. Kleiber. Dr. Kleiber recommended a total fusion of the right foot to solidify the bones; Mr. Wilson does not want additional surgery for fear of another staph infection such as the one following his left knee replacement. Mr. Wilson said that the blood flow to his feet is impaired, increasing the possibility of a staph infection. Mr. Wilson has pain at a level six or seven out of ten in his right foot, his right foot swells if he is on it for an extended period of time, a
