The claimant and employer/insurer offered the following joint exhibits which were admitted into evidence:
Exhibit 1 Claim for Compensation
Exhibit 2 Dr. Koprivica IME
Exhibit 3 Work Partners records
Exhibit 4 Midwest Surgery records
Exhibit 5 St. John's records
Exhibit 6 Dr. Fevurly deposition
Claimant is an assistant supervisor with Missouri Department of Transportation. The claimant injured his right knee on August 18, 2005, when he was helping to install a pipe in a ditch near a construction area. At the time he was operating a loader. He stepped down into the ditch, missed his step due to a hole and twisted his knee. The knee popped and claimant fell. There was immediate swelling and pain. His treatment was initially conservative until an MRI scan revealed evidence of a meniscal tear at which time claimant was referred to Dr. Esch, an orthopedic surgeon, who performed a medial femoral condyle chondroplasty, minimal debridement of the lateral meniscus and a partial medial meniscectomy.
The claimant has ongoing pain in the knee and cannot kneel, squat, or crawl. He has difficulty climbing. He has particular difficulty climbing stairs. The claimant has no prior history of injury to the right knee or any symptomatic condition for which he had any type of care or treatment prior to the date of accident.
The report and opinion of Dr. Brent Koprivica, a specialist in occupational medicine, was admitted into evidence. His opinion is that there is a likely probability that claimant will require care and treatment in the future as a direct necessity of the injury sustained on August 18, 2005. He goes on to indicate that claimant will develop progressive post traumatic degenerative osteoarthritis. He believes the injury and subsequent surgery have permanently aggravated and accelerated the degenerative process which will lead to the necessity for further care and treatment. He is of the opinion that treatment could include delaying interventions such as use of hyaluronic injections or steroid injections. He concludes that it is probable that claimant will require a total knee arthroplasty and the need for revision arthroplasty as well.
The report and opinion of Dr. Fevurly, a specialist in occupational medicine who performed an IME on behalf of employer/insurer, was also admitted into evidence. He indicated that the MRI revealed moderately advanced three compartment degenerative changes. He also noted that there was maceration of the entire medial meniscus and cartilaginous/lateral meniscal tear. Dr. Esch, the treating physician, reported that the articular cartilage problem preexisted the work event, but the medial meniscal tear was the result of the work event on August 18, 2005.
Dr. Fevurly noted that there was significant degenerative arthritis and chondromalacia present in all three compartments of the knee when the claimant underwent arthroscopy on October 7, 2005. Claimant did return to work three days after surgery and was maintained on light duty for a few weeks eventually advanced back to his full and regular duties. Claimant did report persistent medial right knee pain after the surgery. Dr. Fevurly indicated that the prevailing cause of any permanent partial disability to the right knee is preexisting moderately advanced degenerative cartilage changes or the chondromalacia. He believed this is primarily the result of claimant's body habitus and preexisted the work event of August 18, 2005. He believed any need for future total knee arthroplasty is predominately the result of the preexisting arthritis. Dr. Fevurly did indicate that claimant would need to limit prolonged standing and walking and avoid kneeling, squatting, and crawling. He also indicated that claimant should avoid high impact activities such as running and jumping.
Dr. Fevurly issued a supplemental report after receiving a radiology report on bilateral standing knee films which he had previously requested. He indicated that this report documents bilateral knee osteoarthritis showing the right knee is moderately advanced and reveals medial

compartment joint space of three millimeters. There was osteophyte formation in the right knee. The left knee osteoarthritis was mildly advanced and the medial compartment measured four millimeters. Dr. Fevurly indicated that the cartilage height on the left is considered normal and resulted in no ratable permanent disability. The cartilage height on the right indicated permanent partial disability but that it was resulting primarily due to his body habitus. He went on to indicate that it is unlikely that there will be a need for total knee replacement in the next five years based on the remaining cartilage height. The need for total knee replacement would be predominately related to degenerative joint disease resulting from his body habitus and not as a result of the work event on August 18, 2005.
I find the opinion of Dr. Koprivica to be credible and most persuasive in this case. Therefore I find that claimant has met his burden in proving that there is a probability he will need future medical treatment in the future which is related to the work injury. I order that the future medical be left open for any treatment necessary to cure and relive the claimant of the symptoms of the August 18, 2005, injury.
Claimant's attorney has asked for an attorney's fee of 25 percent of all amounts awarded herein. I find that to be reasonable. Consequently, I allow claimant's attorney, Matthew Webster, 25 percent of all amounts awarded herein which shall constitute a lien upon this award.
