Based on a comprehensive review of the evidence, including Claimant's testimony, the expert medical opinions and depositions, the medical treatment records, and the other documentary evidence in this matter, as well as based on my personal observations of Claimant at hearing, I find:
1) Claimant is a 60-year-old car hauler, who has worked for Cassens Transport (Employer) for 19 years delivering new vehicles to car dealerships. Claimant explained that, as a car hauler, he is responsible for loading vehicles, strapping them down, driving to various dealerships in a 600-mile radius, unstrapping the cars and unloading them at the dealerships. He testified that his job duties include setting up ramps and driving the new vehicles on and off the car transport vehicle. Claimant noted that he works out of Kansas City now, but he was employed out of Fenton, when there was a car plant there. He said that he works on average, 50-60 hours per week, up to a maximum of 70 hours per week.
2) Claimant admitted to having a prior right knee injury in 1972 from playing football. He had surgery to the right knee, but testified that he had no problems with the knee and no limitations at work leading up to December 3, 2009 on account of the prior right knee injury.
3) Claimant also admitted having prior claims for left elbow epicondylitis, which was surgically treated, and perhaps a shoulder injury. Further, he broke his right thumb, last October. He denied having any prior or subsequent injuries to his right knee with Employer, except for the injury on December 3, 2009.
4) Claimant testified that on December 3, 2009, he was working in Salina, Kansas unloading minivans at a car dealership. He said that he was coming down ramp \#4 on the transport vehicle, missed the last step, and fell approximately 2 feet and twisted his right knee. He described pain and a burning sensation in the right knee. He noted that he eventually had some swelling in the knee. He said that he continued working that day and finished his duties.
5) Claimant's Driver's Daily Log (Exhibit F) confirms that he was in Salina, Kansas at 1:00 p.m. on December 3, 2009. Records from his personnel file (Exhibit G) confirm that he was then on vacation the next week from December 7-11, 2009.
6) Claimant admitted that he did not report the injury that day. He said that he went back to the terminal in Kansas City, Kansas, and, then, went home to Union, Missouri because he already had a prescheduled physical examination on Monday with his primary care physician, Dr. Borgmann. Claimant testified that he told Dr. Borgmann about his right knee and had an X-ray and MRI taken of the knee.
7) Medical treatment records from Dr. Jamie Borgmann at Patients First Internal Medicine (Exhibit A) confirm Claimant was examined by Dr. Borgmann on Monday, December 7, 2009. Claimant reported a complaint of right knee pain. The medical records contain the following history: "HX of operation at age 18 for torn cartilage. Has started having
