All evidence presented has been reviewed. Only testimony and evidence necessary to support this award will be summarized.
- Claimant is 61 years old, attended but did not graduate high school, but later obtained a GED. Claimant did not receive any vocational or post-high school training. Claimant obtained a commercial drivers license (CDL) when he was 18, and spent his working years as a truck driver. For approximately 25 years, Claimant drove a milk delivery truck for Prairie Farms Diary (Employer). Claimant's work duties included loading his truck with milk crates piled 6 crates high on a dolly, delivering milk in the same fashion, stacking the milk for customers, and
collecting payment. Claimant drove a "time sensitive" route that included hospitals and educational facilities in and around St. Louis, Missouri. ${ }^{1}$ If Claimant was physically unable to "timely" deliver his load, Employer would send out an assistant to the delivery site to help.
- On March 19, 2009, while loading his delivery truck, Claimant fell backwards twisting his right knee. ${ }^{2}$ Claimant was initially provided conservative medical treatment, and when he did not improve an MRI of his right knee was obtained. The MRI demonstrated degenerative joint disease, a prominent joint effusion, and a previous lateral meniscectomy. Claimant was referred to Dr. Haupt, an orthopedic surgeon. ${ }^{3}$ Dr. Haupt continued Claimant's conservative medical care until April 30, 2009, when Dr. Haupt opined Claimant required arthroscopic surgery. On May 1, 2009, Claimant underwent right knee surgery where extensive tearing of the lateral meniscus was found along with removal of a loose body. Dr. Haupt's post-operative diagnoses included: extensive tearing of the right lateral meniscus; grade IV articular cartilage erosion of the entire tibial plateau; loose body formation in the medial gutter; and grade III chondromalacia of the patellofemoral joint. Post-operatively Claimant received physical therapy, and was fitted with both a knee stabilizing brace and a varus unloader brace. When Claimant completed physical therapy and work hardening a functional capacity examination (FCE) was obtained. On August 6, 2009, Dr. Haupt reviewed the FCE results and opined Claimant was at MMI. Dr. Haupt placed the following permanent work restrictions: lifting from floor to neck of no greater than 40 pounds; knuckle to shoulder lifting of no greater than 40 pounds; shoulder to overhead lifting of no greater than 40 pounds; a 40 pound restriction for carrying up and down stairs, or with use of a dolly for up or down stairs; and a 60 pound carrying limit if on a flat surface. Due to the level of his restrictions, Employer was unable to accommodate Claimant and his employment terminated. Claimant has not returned to employment after his release.
- Prior to the primary injury, Claimant had documented and rated preexisting injuries/ conditions that included: a) his right knee; b) his left wrist; c) an anxiety disorder; and d) hypertrophic obstructive cardiomyopathy (HOCM).
a) During January 2000, Claimant twisted his right knee while walking down a ramp at work. An MRI indicated Claimant had an extensive tear of his right lateral meniscus. Surgery was recommended. At surgery Dr. Haupt noted that in addition to the lateral meniscus tear, Claimant was found to have anterior and posterior meniscus tears, and most of the anterior horn of the lateral meniscus was resected. Following post-operative care, Claimant returned to work, but found the residual injury "slowed him down," and he continued to experience pain in the knee with bending, standing for long periods, or stepping in and out of his truck. Claimant settled his claim with Employer for 20\% PPD referable to his right knee. ${ }^{4}$
b) During 2004, during a milk delivery, Claimant injured his left wrist. Initially, Claimant received medical treatment for a left wrist sprain, but as his condition worsened he was referred to a hand surgeon. Ultimately, Claimant underwent left wrist fusion for a SLAC wrist
[^0]
[^0]: ${ }^{1}$ Due to the nature of the business conducted, "time sensitive" deliveries included most of the major St. Louis Hospitals.
${ }^{2}$ Claimant also injured his low back and left elbow, but these injuries resolved with conservative medical treatment.
${ }^{3}$ Dr. Haupt died unexpectedly shortly after Claimant's release from treatment, and neither party was able to depose him.
${ }^{4}$ During 2000, Claimant also suffered a left elbow strain and settled his case with Employer for 7.5 % PPD referable to the left elbow. Dr. Poetz did not rate this injury. During 2011 Claimant underwent a partial knee replacement.
during which bone was removed from his left iliac crest for grafting. Since surgery, Claimant has retained hardware in the wrist, is unable to bend the wrist, has limited rotation of his wrist, and is unable to lift with the wrist. Claimant is left-handed. Claimant continues to experience difficulty with writing, has left hip pain, is unable to play sports, and while working frequently required assistance to complete his "time sensitive" deliveries. Claimant settled his case with Employer for 35 % PPD referable to his left wrist.
c) Claimant suffered his first anxiety attack after his first knee surgery in 2000. During that attack Claimant sought care in the emergency room and was treated with medication. During 2004 through 2008, Claimant was provided Ativan prescriptions through his internist on at least 12 occasions with each prescription giving multiple refills. Claimant testified he would have frequent feelings of being "closed in," and had problems with depression and sleeping. During August 2009, ${ }^{5}$ the internist placed Claimant on Celexa and Ambien after Claimant complained of being tearful, depressed, and nervous. ${ }^{6}$ Cla
