Numerous medical exhibits were admitted into evidence. Claimant's Exhibit B was the deposition testimony of P. Brent Koprivica, M.D. Dr. Koprivica testified that he was board certified in emergency and in occupational medicine. He stated that he evaluated Claimant on November 23, 2009 and on June 18, 2010.
Dr. Koprivica provided a detailed history of Claimant's injuries in the 1996 and 2008 accidents. He noted that Claimant had reconstructive surgery to his ACL and PCL in his left knee as a result of the 1996 motorcycle accident. He noted that Claimant had a bipolar hip replacement on the left side. He noted that Claimant had a tendon lengthening procedure of his left lower extremity due to a shortening of the calf muscle. He stated that Claimant had multiple surgeries for his left knee and left lower extremity injuries.
Dr. Koprivica testified that Claimant fractured his left clavicle in the 1996 accident and that he had a muscle tendon transfer. He stated that Claimant required surgery on his left hand to allow him to straighten out his fingers. He noted Claimant brachial plexus injury.
Dr. Koprivica testified that Claimant's 2008 accident resulted in a "significant" traumatic head injury with a left basilar skull fracture, a subdural hematoma and a subarachnoid hemorrhage or bleeding inside the skull. He stated that Claimant's injuries caused him to lose his hearing in his left ear. He stated that Claimant sustained a left acetabular fracture, a left tibial plateau fracture, and a peroneal nerve injury which resulted in a left foot drop. He stated that Claimant lacerated his spleen in the accident. He also stated that Claimant developed facial pain and visual floaters due to the accident.
Dr. Koprivica concluded that Claimant's February 2008 accident was the direct, proximate and prevailing factor in causing each of the injuries as set out above. He stated that all the treatment Claimant received for his injuries, including the hearing aid was reasonable and necessary. He stated that Claimant developed stomach ulcers due to the medication required to treat his injuries. He stated that Claimant's back complaints were related to his hip, knee and foot injuries in the February 2008 accident. He stated that Claimant's inability to do prolonged standing, walking and sitting was due to the February 2008 accident.
Dr. Koprivica concluded that Claimant would need future treatment for his left hip and left knee. He stated that Claimant needed a scooter for gait assistance and that he needed a lift to transport the scooter in his vehicle. He stated that Claimant needed chronic pain management, aqua therapy, a left knee brace and an AFO brace. He stated that Claimant was temporarily and
totally disabled from February 5, 2008 to February 2010 or the last date in which Claimant received rehabilitation care from Corporate Care.
Finally, Dr. Koprivica concluded that Claimant was permanently and totally disabled due solely to the injuries Claimant sustained in the February 5, 2008 accident at work. He stated that if Claimant were found not to be permanently and totally disabled due solely to his injuries in the 2008 accident; that it would be his opinion that Claimant had sustained a permanent partial disability of 35 percent to his body as a whole due to his closed head injury which included his hearing loss, headaches, facial pain and weakness and all the "residuals from the head injury." He concluded that the February 5, 2008 accident had resulted in a permanent partial disability of 35 percent to Claimant's left hip at the 207 week level, and a 40 percent permanent partial disability at the 160 week level due to his knee injury and foot drop. He stated that Claimant needed major work restrictions.
On cross-examination by Claimant's employer, Dr. Koprivica admitted that he was not board certified in orthopedics, neurosurgery or neurology. He admitted that 98 to 99 percent of his evaluations during the preceding five years were at the request of claimants or plaintiffs.
Dr. Koprivica admitted that he understood that Claimant was left hand dominant until he sustained the severe injuries to his left upper extremity in the 1996 motorcycle accident. He admitted that he understood that Claimant had to become right hand dominant after his 1996 injuries. He admitted that he believed that Claimant's injuries from his 1996 motorcycle accident were a "significant" hindrance or obstacle to his employment or reemployment. He admitted that it was significant that Claimant required a scooter after his 1996 motorcycle accident.
Dr. Koprivica admitted that Claimant needed significant work restrictions after his 1996 accident and that he needed a job which would allow him to sit and stand as needed. He admitted that he had estimated that Claimant's disability from the 1996 motorcycle accident was 35 percent of the left knee, 35 percent of the left hip and 50 percent of the left upper extremity.
Claimant's employer offered into evidence the deposition testimony of Charles Tuen, M.D. and Bernie McCaskill, M.D. Dr. Tuen, board certified in neurology and clinical neurophysiology, testified that he examined Claimant on August 29, 2011. He noted that Claimant's memory, attention and concentration were not impaired. He noted that Claimant's speech was clear. He noted that Claimant's vision test results were normal.
Dr. Tuen found that Claimant had severe paralysis of most of the muscles in his left arm and some weakness of his right thumb. He stated that Claimant had a severely decreased range of motion of his left hip and left knee and a severe left foot drop. He stated that Claimant did not require any assistive devices to ambulate.
Dr. Tuen concluded that Claimant's subdural hematoma and the subarachnoid hemorrhage from the 2008 accident had resolved. He concluded that Claimant's cognitive functions were within normal limits. He concluded that Claimant's left hip and left knee replacements after the 2008 accident "most likely related to the 1996 motorcycle accident." He concluded that Claimant's left foot drop was caused by the 2008 accident.
Finally, Dr. Tuen concluded that the only disability caused by Claimant's 2008 accident was a 100 percent hearing loss in Claimant's left ear and a severe left foot drop. He concluded that the 1996 motorcycle accident had resulted in an almost complete loss of function of Claimant's left upper extremity, as well as Claimant's current left hip and left knee pain and stiffness and his left arm and back pain. He concluded that Claimant's left foot drop from the 2008 accident had resulted in a permanent partial disability of 7 percent of the whole person.
On cross-examination by Claimant, Dr. Tuen admitted that he had reviewed the AMA Guide to come "up with that number" for his disability rating. Later, he explained that "I cannot tell you exactly how I came to that number". On cross-examination by the Second Injury Fund, Dr. Tuen stated that he believed that Claimant was "trying to exaggerate his symptoms". He indicated that he believed that the 2008 accident may have accelerated Claimant's need for the hip and knee replacements.
Dr. McCaskill, a board-certified orthopedic surgeon, testified that he had performed hip and knee replacement surgeries and back and ankle surgeries. He noted Claimant's medical history. He stated that Claimant sustained a traumatic brain injury in the 1996 accident, a left clavicular fracture, a left brachial plexus injury, a fracture of both bones of his left arm, a right forearm fracture and multiple left metacarpal fractures. In addition, he stated that Claimant sustained a left femoral head fracture and a left knee dislocation. He noted that Claimant had injured his peroneal nerve on the left side causing foot and ankle problems.
Dr. McCaskill noted that as a result of the 2008 accident; that Claimant complained of intermittent headaches, memory loss, deafness in his left ear, a left dry eye and eye dysfunction, left sided facial sensitivity, intermittent and diffuse back and left arm pain, continuous and severe left hip pain, an inability to bear weight on his left lower extremity, continuous and diffuse left knee pain and weakness, left lower extremity weakness and numbness associated with his peroneal nerve palsy.
Dr. McCaskill concluded that Claimant's 1996 left knee dislocation and the subsequent numerous surgeries on Claimant's left knee had resulted in severe end stage posttraumatic tricompartmental degenerative arthritis of Claimant's left knee. He concluded that Claimant's left knee replacement in 2009 was due to the severe end stage arthritis and not any injury that Claimant allegedly sustained in the 2008 accident. He noted that it was not even certain that Claimant had sustained a tibial plateau fracture in the 2008 accident as diagnosed in the emergency room. He noted that it was not certain that Claimant had sustained any knee injury in the 2008 accident and that Claimant had not sustained any disability due to any alleged knee injury in the 2008 accident.
Dr. McCaskill concluded that Claimant's left hip total replacement in 2008 was due to the fracture in the 2008 accident. He concluded, however, that Claimant had not sustained any disability as a result of the total hip replacement, because afterwards Claimant's hip had returned to its pre-accident condition. He stated that he found no objective basis for the magnitude of Claimant's left hip complaints.
Dr. McCaskill also concluded that Claimant did not have any cognitive dysfunction. He stated that Claimant's basilar skull and temporal bone fractures and the hematomas had healed with no residuals. He stated that the 2008 accident did cause Claimant's complete loss of

hearing on the left side. He indicated that excluding the hearing loss, that Claimant had sustained a permanent partial impairment of 5 percent to the body as a whole due to his head injuries.
Dr. McCaskill concluded that Claimant's facial nerve paresis from the 2008 accident had resolved with no permanent impairment. He stated that Claimant's possible pulmonary contusion and rib fractures from the 2008 accident had resolved. He indicated that Claimant's possible splenic laceration and liver contusion from the 2008 accident had healed.
Dr. McCaskill concluded that Claimant's left peroneal palsy was caused by the 2008 accident and that it had resulted in a permanent partial impairment 17 percent to the whole body. He indicated that the treatment Claimant received for the peroneal nerve palsy was reasonable and necessary. He also concluded that Claimant's 2008 endoscopic gall bladder procedure was more likely than not caused by the 2008 accident.
Dr. McCaskill also rendered impairment ratings for Claimant's 1996 motorcycle accident injuries. He concluded that Claimant's hip fracture in the 1996 accident had resulted in a permanent partial impairment of 15 percent to the body as a whole. He stated that Claimant's severe left knee dislocation in the 1996 accident had resulted in a permanent partial impairment of 30 percent to the whole body.
Dr. McCaskill concluded that Claimant's cervical spine nerve injury on the left side was Claimant's most significant injury from the 1996 motorcycle accident. He stated that Claimant had a marked limitation of motion of his left shoulder and severe atrophy. He concluded that Claimant had essentially no function of his left upper extremity. He concluded that Claimant had sustained a permanent partial impairment of 54 percent to his body as a whole, or 90 percent of the left upper extremity due to the 1996 motorcycle accident. He noted that he had used the AMA Guides in rendering his rating.
Finally, Dr. McCaskill noted that Claimant had "significant" restrictions in his ability to walk and stand prior to his 2008 accident. He stated that Claimant's possible need for an electric scooter was due entirely to Claimant's injuries in the 1996 motorcycle accident. He noted that Claimant could move on and off the examining table without difficulty. He noted that Claimant's lack of use of ongoing pain medication was inconsistent with Claimant's complaints of "significant" pain. He concluded that Claimant could do light work as long he was not required to walk or stand for more than one hour in an eight hour work day. He stated that Claimant did not need any ongoing pain management and that any treatment Claimant needed for his left knee was due to the 1996 and not the 2008 accident.
On cross-examination by Claimant, Dr. McCaskill testified that he examined Claimant on April 4, 2011. He explained the differences between impairment and disability. He stated that Claimant's medical records showed that Claimant had told medical providers that he had 15 surgeries on his left knee prior to the 2008 accident. He acknowledged that Dr. Christensen had indicated in 2001 that Claimant had mild complaints regarding his left hip and left knee. He stated that the 1996 accident had effectively resulted in an amputation of Claimant's left upper extremity at the shoulder level because Claimant could basically no longer use his left arm.
On cross-examination by the Second Injury Fund, Dr. McCaskill reiterated that in his opinion that Claimant's left knee total replacement was due to Claimant's end stage posttraumatic degenerative arthritis caused by the 1996 accident and not to any alleged knee injury in the 2008 accident. He again stated that it was questionable that Claimant had sustained a tibial plateau or periarticular fracture in the 2008 accident and that if Claimant had sustained either type of fracture it would not have resulted in the need for a total knee replacement within one year of the accident.
On redirect examination, Dr. McCaskill indicated that Claimant needed an electric scooter due to his left upper extremity impairment which would prevent him from using a manual scooter or wheelchair.
