Dr. Koprivica authored an Independent Medical Evaluation dated August 6, 2008 and an addendum report dated April 16, 2011, both at the request of Ms. Jones. Dr.
Koprivica's deposition was also offered. Dr. Koprivica opined that the fall on July 26, 2005 was the direct, proximate, substantial, as well as prevailing, factor in the development of symptomatic internal derangement of the left knee that necessitated subsequent treatment. Due to the injury on July 26, 2005, Dr. Koprivica opined that Ms. Jones had a 75 percent permanent partial disability of the left lower extremity at the 160 week level. He also felt that she may be a candidate for a total knee arthroplasty or total knee replacement, if her medical condition permitted it. The July 2005 work injury would be a substantial factor in her need for a left knee replacement.
In his original 2008 report, Dr. Koprivica relied on Ms. Jones testimony and determined she was permanently and totally disabled due to the last accident alone and the she had no permanent pre-existing disabilities. Dr. Koprivica's addendum changed his opinion. In 2011 he opined that her diabetes was disabling prior to July 26, 2005, and issued a 15 percent permanent partial disability for her pre-existing diabetes. During his deposition, Dr. Koprivica deferred to Mary Titterington as to whether or not the restrictions and limitations he identified for the July 25, 2005 injury were permanently and totally disabling. He opined that Ms. Jones was permanently and totally disabled and that it would be caused by the primary injury alone if a vocational expert determined that the napping and laying down due to pain were considered permanently and totally disabling. Dr. Koprivica opined that Ms. Jones reported napping and lying down as a pain behavior was consistent with the severity of her knee condition (Exhibit A, 22:20). Dr. Koprivica admitted that Ms. Jones knee pain was a major contributor to her sleep interruption. (Exhibit A, 45:9). He also admitted that even before he knew of any limitations Ms. Jones had prior to the last injury, he thought her restrictions on her knee and her limitations due to her knee pain were enough to permanently and totally disable her (Exhibit A, 47:19).
Dr. Koprivica suggested permanent restrictions due to Ms. Jones 2005 knee injury. He restricted her from squatting, crawling, kneeling, and climbing. He also suggested that due to her knee condition she need a cane and cart to get a round. Dr. Koprivica opined that Ms. Jones should limit time on her feet to less than one to two hours in an eight hour period and should be limited to ten minutes of standing in any one interval with flexibility of sitting whenever necessary. He recommended a sedentary physical demand level. He stated that she had issues regarding sleep deprivation and need to recline and doze during the day.
Mary Titterington, a Vocational Expert, offered an opinion at the request of the employee. Ms. Titterington issued a report on January 4, 2010 and testified by deposition on January 11, 2012. Ms. Titterington's opined that Ms. Jones work injury to her knee has removed her from the work force when combined with her low academic skills and very limited mobility. On cross-examination Ms. Titterington admitted that Ms. Jones never reported needing to lie down during the day prior to the July 26, 2005 work injury. She also admitted that Ms. Jones was not having trouble performing her job prior to her work injury, and that she had good attendance. Ms. Titterington further admitted that Ms. Jones pain and standing and walking limitations were the main reasons she was unable to
meet the essential characteristics of work including: ability to report to work consistently, stay on task throughout the work day and meet productions goals for quality or quantity of work (Exhibit C, 29:22). Ms. Titterington also opined that a need to recline during the day would remove her from the work force in isolation (Exhibit C, 31:2).
Allan Schmidt, Ph.D., was retained by the employee to render an opinion on Ms. Jones psychological condition. His reported I dated April 9, 2010 and his deposition was taken January 3, 2012. He opined that Ms. Jones had 10\% pre-existing psychological disability and a 15 % permanent partial psychological disability due to her last injury. He admitted she never saw a specialist for any psychological problem prior to the primary work injury. She was not taking any medication for any psychological condition at the time of the primary injury, and Dr. Donaldson had been able to wean her off her depression medication because she had been doing better with her depression symptoms. He also admitted that Ms. Jones was not mentally retarded, but her IQ of 73 was borderline intellectual functioning. He did diagnose her as having a reading disorder, though admitted poor sleep could have altered her testing scores.
Dr. Frevert, treating physician, offered a rating report dated September 20, 2006. He also testified by deposition on July 2, 2012. Dr. Frevert opined that Ms. Jones had a 25 % permanent partial impairment of the left lower extremity at the level of the knee due to the last injury. He opined that she had a 10 % pre-existing impairment at the knee due to arthritis, but that she did not report any limitations due to her knee before the injury and there was no reason to believe it was symptomatic. He restricted claimant from prolonged standing or walking and repetitive stair climbing. He stated she could ambulate as tolerated but should avoid carrying or lifting greater than 5-10 pounds. He admitted that it would be reasonable for Ms. Jones to report sleep interruption from her knee pain.
Dr. Clymer issued an Independent Medical Evaluation on February 20, 2012 at the request of the Employer/Insurer. He testified by deposition on July 9, 2012. He admitted that Ms. Jones was doing well with her knee prior to the July 26, 2005 injury. He opined that Ms. Jones had osteoarthritis, morbid obesity, diabetes, hypertension, depression, hyperlipoidemia, and some pervious degenerative arthritis pre-dating her work injury. He determined that her primary problem was obesity and arthritis in the left knee. He assigned a 20 % permanent partial disability due to the work injury and a pre-existing 15 % to the knee due to arthritis and obesity. He suggested that she cannot manage prolonged standing or walking and could work a sedentary job.
Terry Cordray, Vocational Expert, was retained on behalf of the Employer/Insurer. He issued a report on May 23, 2012 and testified by deposition on July 12, 2012. Mr. Cordray opined that based on her sedentary work restrictions and background she would be able to work as a parking garage cashier, a telemarketer, or a security monitor. He admitted that if she needed to lie down, it would be totally disabling.
Mike Dreiling, Vocational Expert, wrote a report at the request of the Second Injury Fund. His deposition was taken July 9, 2012. Mr. Dreiling testified that the limitations due to the July 26, 2005 injury alone, there is no employment an employer could reasonably be expected to hire Ms. Jones for (Exhibit II, 13:17). He indicated that her need to sit-down for work, and potentially needing to lie down, doze off and use assistive devices in the work setting would preclude her from working.
