The administrative law judge found the opinion of Dr. Chabot regarding employee's restrictions to be more persuasive than that of Dr. Volarich's. However, Dr. Chabot only evaluated employee in regards to his primary injury of September 30, 2004. Thus, his restrictions were based solely on this injury. Therefore, neither his restrictions nor ultimate opinion addressed whether employee was permanently and totally disabled as a result of the combination of his primary injury and preexisting disabilities.
On the other hand, Dr. Volarich evaluated employee's primary injury and each of his preexisting disabilities. Dr. Volarich also evaluated the combined effects of the primary injury and preexisting disabilities in making his determination that employee was permanently and totally disabled. Therefore, Dr. Volarich's opinion is more persuasive and credible in addressing whether employee was permanently and totally disabled.
The administrative law judge also reasoned in his award that not all of employee's preexisting injuries synergized with his primary injury. The administrative law judge specifically set forth that employee's prior neck injury and right knee injury synergized with the primary injury. He then noted that there was insufficient evidence to show that the left elbow, left wrist or left ${ }^{[2]}$ knee injuries limited employee's pre-accident activity.
The Commission disagrees with this determination. The competent and substantial evidence shows that all of employee's prior injuries synergize with his primary injury to cause a greater disability than their simple sum. Employee testified that he still suffers pain and has diminished grip strength due to his left wrist and elbow injuries. He also testified that he cannot squat, kneel, or climb a ladder any longer due to the pain and potential that his left knee could "pop out" as a result of the prior injury to that knee.
Dr. Volarich testified that employee's primary injury and preexisting disabilities were all a hindrance to his reemployment. In his opinion, the combination of employee's primary injury and preexisting disabilities caused employee to be permanently and totally disabled.
The administrative law judge also erred when he "accepted" Mr. England's "alternative opinion" that employee was still employable. Mr. England did not opine that employee was still employable. Mr. England did discuss alternative conclusions regarding employee's employability depending on whether one accepted the restrictions of Dr. Chabot or Dr. Volarich in his report. His report notes that under Dr. Chabot's restrictions, employee could perform some types of sedentary work, while under Dr. Volarich's restrictions, employee would not be capable of working in the open labor market. However, the administrative law judge ignores Mr. England's ultimate opinion that employee is not employable in the open labor market. Thus, Mr. England clearly and unequivocally adopted Dr. Volarich's restrictions in finding employee unemployable, and did not opine directly or alternatively that employee was still employable.
Furthermore, as set forth above, Dr. Chabot's restrictions are based only on employee's primary injury, and therefore not as credible or persuasive as those of Dr. Volarich. As such, reliance on those restrictions to find that employee is employable was erroneous.
Based upon the foregoing, we do not believe any employer would reasonably be expected to hire employee in his present physical condition. Pavia, 118 S.W.3d at 234. Employee is permanently and totally disabled and unable to compete in the open labor market. We accept Dr. Volarich's and Mr. England's testimony that employee's inability to compete in the open labor market is due to the disability he suffers from the synergistic effect of the combination of his primary work injury and pre-existing disabilities. Therefore, the Second Injury Fund is liable to employee for permanent total disability benefits. See §287.220 RSMo.
