Claimant is a sixty-four year old high school graduate with certification from Bailey Technical School in diesel and automotive mechanics and aircraft mechanic training with the United States Navy in the 1960s. He was honorably discharged after four years of service. He worked as a diesel mechanic before and after military service for a total of thirty four years. As a diesel mechanic for Employer, he performed brake work, maintained and overhauled engines, and welded.
In the performance of his work, he used hand tools, hydraulic pressure, large impact tools, jacks and wrenches weighing up to fifty pounds. Climbing, kneeling, working in awkward positions, and lifting up to one-hundred pounds were activities Claimant performed without help on a daily basis. Claimant input a limited amount of data into the computer but his performance did not require bookkeeping, inventory, receiving or supervisory skills. Claimant worked for Employer for thirty years. He has not worked anywhere since he was injured at work on June 2, 1999 due to the work restrictions, inability to perform tasks and his belief that he is no longer a good employee.
On June 2, 1999, Claimant was working on a tractor trailer when his foot became caught on the running board, twisting his right knee and causing it to pop. Dr. Fagan performed surgery on Claimant's right knee on June 9, 1999. After surgery he had weakness, pain, and limited range of motion, problems in climbing ladders and walking on uneven surfaces, swelling, left knee pain and he was unable to complete work hardening. Dr. Fagan released him from treatment on January 11, 2000 with permanent restrictions of no kneeling, squatting, crawling or lifting heavy weights, but he could not return to Employer with those restrictions.
Dr. Maylack performed Claimant's right knee replacement in January 2002 and a revision surgery in February 2003. Claimant received workers' compensation benefits for the June 1999 injury based on PPD of 30\% of his right knee (Exhibit B). Claimant testified his right knee is worse since the June 1999 injury, with increased pain, decreased range of motion, popping, stiffness, swelling and difficulty in standing or sitting, although walking is better.
Now he has good and bad days and has to lay down when activity or weather causes general aches. He spends the day in the house when the pain is worse.
Upon cross-examination, Claimant admitted that before the June 1999 injury, he could bend, stoop, crawl, climb, and lift heavy tools in awkward positions, while working more than forty hours per week without prescription medication, accommodations or restrictions.
Before the June 1999 injury, Claimant had sustained injuries to both his knees, back, neck and left wrist, but he returned to a physically demanding job without restrictions after each injury, did not change jobs, and worked overtime without medication prior to the June 1999 injury.
- Claimant missed six weeks work after arthroscopic surgery performed by Dr. Vierling on his right knee on March 4, 1987. He was released to full duty, without restrictions. After treatment, he moved more slowly, standing or walking caused pain, he was unable to straighten the knee or squat, and it swelled. Mowing with a push mower and gardening were more difficult and required Claimant to take aspirin.
- Claimant required surgery on his left knee after injuring it at work on April 4, 1996. Six weeks later, he returned to work without restrictions and settled the case with his Employer for 30\% PPD of the left knee. After treatment, Claimant complained of weakness, pain, limited range of motion, increased difficulty climbing ladders, and walking on uneven surfaces or down stairs. He slowed down, limited heavy lifting, and switched to a riding lawnmower.
- Dr. Mitchell Rotman performed a carpal tunnel release on Claimant's left wrist in August, 1997. After missing five weeks from work, Claimant returned to work without restrictions and settled the case with his Employer for 31.5 % PPD of the left wrist, due to limited range of motion, pain, decreased grip strength, the need for help when working, and increased use of aspirin.
- Claimant received conservative treatment from Dr. Lord in the 1980's for back problems. The treatment consisted of physical therapy, traction and a corset. After the injury, he experienced pain when bending to lift heavy objects or when engaged in twisting motions, and he continued to seek help at work and home.
- Claimant sought treatment from Dr. Caskanett for neck problems in the 1980's. Claimant complained of pain through his shoulders which slowed him down and caused him to ask for help at work and home.
Dr. Volarich examined Claimant twice for knees, back, left wrist and neck problems. Claimant also interviewed with Mr. Brethauer, a vocation rehabilitation counselor. Since the 1999 injury, Claimant's problems include bilateral knee weakness and difficulty walking on uneven surfaces, climbing, and difficulty with prolonged sitting, standing, driving, sleeping, and activity. Weather changes occasionally affect his back and knees. Prior to the June 1999 injury, he stopped turkey hunting and walking in streams to fish. Claimant takes aspirin for his knees, wrist and back.
