James Taylor is a 52 year old man who lives with his wife at 5040 N.E. $56^{\text {th }}$ Place, Kansas City, Mo. 64119. He is a 1975 graduate of North Kansas City High School, and completed two years of college courses at Central Missouri State University in Warrensburg, Missouri. He was majoring in Music. He has a law enforcement background, having completed training in first aid, security, and carrying concealed weapons.
On 4/2/03 Mr. Taylor was employed by the City of Kansas City, Missouri at the city jail, the Municipal Correctional Institution, as a correctional officer/security guard. His job required driving a bus, picking up inmates from police departments, transporting inmates to jail and checking them in, which involved taking their money and their clothes, and giving out uniforms and bed linens. He ran the inmate commissary which involved stocking shelves with food, selling food to the inmates, logging the inmates' money in and out of the computer, watching the inmates, and returning clothes and property to inmates who were leaving the jail. During the course of a day, claimant stood, walked, pushed, pulled, bent, drove, reached overhead and lifted from one to thirty pounds. He was under the restrictions from Joseph Ketcherside, M.D., including: no lifting greater than 30 pounds; no prolonged sitting or standing; and no repetetitive bending or twisting. The claimant was required to take a pre-employment physical prior to employment with the City, and was allowed to work without restrictions, including "the yard", despite numerous prior lower back surgeries and four left knee surgeries.
On 4/2/03, while handing out clean clothes to inmates, an un-restrained inmate, a 23 year old male, 5'10" tall and 160 pounds allegedly didn't like the wash cloth that he was given, and threw it into another officer's face. He then snapped a towel into Mr. Taylor's face. The claimant and another officer tried to restrain the inmate, but the inmate broke free and ran down the hall. The claimant called for assistance and 2 more officers blocked the inmate at the end of the hallway. Then, all four officers, including the claimant, were wrestling with the inmate. The inmate and someone else stepped on the claimant's left foot. Then everyone fell on the claimant. The total combined weight was approximately 1300 pounds. The claimant fell through the doorway, landing flat on his back, with his right knee flexed and in a valgus direction, and he struck his posterior skull. The claimant was in severe pain in his low back and could not move his right leg. He was transported to North Kansas City Hospital by ambulance, and underwent a CT scan, and X-rays. He was told that he had a torn right ACL, and was placed in a knee brace and referred to Jonathan Blake, D.O. He told Dr. Blake about his low back pain, but was not referred to anyone else at that point. Dr. Blake placed him in an immobilizer, gave him medications, and prescribed him to undergo physical therapy for two days at North Kansas City Hospital, with no relief of his symptoms. He then underwent a right knee allograft hamstring ACL reconstruction at St. Mary's Hospital, on May 15, 2003. Post operatively, he underwent physical therapy at SERC for approximately five months for his right knee and low back pain. During physical therapy, he had a new onset of right lower extremity pain, cramping, numbness, tingling and right buttock burning sensation. He was referred to Dr. Zarr for his low back pain. At this point, he was five months post-right ACL reconstruction. He had symptoms of right knee
instability, swelling, low back pain, right foot cramping, but denied calf cramping, numbness or tingling to either foot. He was treated by Dr. Zarr, and was advised that the back pain was secondary to his gait. He was recommended to have a right total knee replacement, and to continue with Dr. Blake and physical therapy.
In October 2003 claimant underwent a Functional Capacity Evaluation at SERC, following which Dr. Zarr gave him a 5\% BAW rating and advised him to follow up with Dr. Blake. He was returned to work on light duty. However, he was advised by his employer that there was no position available that could accommodate light duty restriction. Dr. Blake referred him to North Kansas City Pain Management Clinic. He underwent an EMG by Dr. Hollenbeck and returned to Dr. Charapata, who ordered X-rays and a CT scan. On December 17, 2003 he had a $2^{\text {nd }}$ spinal cord stimulator inserted at Heartland Spinal Hospital. Thereafter, in 2004, claimant underwent two epidural steroid injections under the direction of Dr. Charapata, without subjective relief. On 10/10/05 claimant underwent an elective primary left total knee arthroplasty by orthopedic surgeon, William Bohn, M.D. In 11/05, when leaving his home to go to his first post-operative appointment with Dr. Bohn, following his left primary total knee arthroplasty, he slipped and fell on an icy d
