Claimant saw Dr. John Putnam, an orthopedic surgeon in Springfield, Missouri, on March 3, 2017. In that visit, Dr. Putnam examined Claimant's shoulder and reviewed the diagnostic studies. Dr. Putnam concluded that the pathology was a gradual deterioration caused by aging, hereditary, previous trauma and normal activities regardless of the alleged work injury. Dr. Putnam said in his report that the radiograph "confirms end-stage tricompartmental osteoarthritis with bone-on-bone findings and sclerotic changes on

both sides at the glenohumeral joint." (Ex. H). Dr. Putnam concluded that any need for additional treatment was unrelated to the work incident:
Regardless of injury sustained 1/30/2017, any future treatment to the left shoulder would "reasonably flow" from documented osteoarthritis. I do think the patient will eventually need a total shoulder arthroplasty procedure and in my opinion this is not the responsibility of workman's compensation.
(Ex. H). Upon receiving Dr. Putnam's opinion, Employer sent Claimant a denial letter on March 20, 2017.
Claimant thereafter saw Dr. Hubbard who performed a left shoulder Celestone injection. Claimant next went to Dr. William Wester on June 29, 2017. Dr. Wester's report of Claimant's initial office visit on June 29, 2017, does not suggest that Claimant's shoulder pain is work related, nor does it suggest that Claimant was asymptomatic prior to a work incident. Dr. Wester reported as follows:
**History of Present Illness**
56-year-old male presents complaining of left shoulder pain, growing significantly worse over the last several months. He has a history of a SLAP tear in 2008. Chris Miller had repaired that. He had done well up until about a year ago when he began having stiffness and pain in the shoulder. It has progressed markedly, and it has reached a point now where he has significant restriction of mobility, as well as pain with mobility and pain at night. He has significant limitations with his occupation.
(Ex. G, p. 125). The medical record of this initial visit between Claimant and Dr. Wester was completed just five months after the work incident on January 30, 2017. Dr. Wester went on to perform the total arthroplasty. He released Claimant from active care on January 18, 2018, to perform activities as tolerated with a 40-pound lifting restriction.
Dr. Ted Lennard holds a specialty certification with the American Board of Physical Medicine and Rehabilitation. He examined Claimant at the request of Employer on February 20, 2019. Based on Claimant's history, examination, and a review of the medical records, Dr. Lennard concluded that the work incident on January 30, 2017, was not the prevailing factor in the onset of the left shoulder osteoarthritis ultimately requiring a left total shoulder replacement. Dr. Lennard said the treatment for the left shoulder pain after January 30, 2017, did not flow from the work event. Dr. Lennard emphasized that Mr. Edwards' left shoulder MR arthrogram performed on February 14, 2017, which was 2 weeks after the work event, revealed severe osteoarthritis in the shoulder joint and no evidence of an acute rotator cuff tear. He noted that the left shoulder radiographs on June 29, 2017, revealed severe osteoarthritis of the left shoulder, complete loss of the joint space, subchondral sclerosis and osteophyte formation, all of which Dr. Lennard said takes years to develop, and are known to cause progressive stiffness, pain, and weakness.
Dr. Lennard rated the left shoulder at 35 percent to the left upper extremity at the 232-week level, of which 17.5 percent could be attributable to a pre-existing left shoulder condition requiring surgical treatment in 2008, and the remaining amount was referable to degenerative arthritis requiring the total shoulder arthroplasty on August 1, 2017.
Dr. Mitchell Mullins is board certified in emergency medicine and is a certified life care planner. He examined Claimant on October 15, 2018, at the request of Claimant's attorney. Dr. Mullins determined that the diagnosis from the present injury was 1) rotator cuff tear, infraspinatus with infraspinatus

tendinopathy left shoulder; 2) osteoarthritis left shoulder; and 3) status post total shoulder arthroplasty July 31, 2017. Dr. Mullins opined that the accident on January 30, 2017 work incident was the prevailing factor causing the rotator cuff tear in the left shoulder resulting in the care which included the total shoulder arthroplasty. While he admitted that the injury did not cause all of the degenerative changes in the left shoulder, he believed that the work over the previous 15 years contributed to the arthritis. He opined that the caused a tear to the rotator cuff which then became a symptomatic left shoulder, which in turn resulted in the care provided and flowed from the January 30, 2017 injury. Mr. Mullins testified, as follows:
Q. And would it be accurate again, just so I'm understanding, if he is not presenting with any pain and he's not going to the doctor with any pain prior to this January 30 injury, then we can say that the January 30 injury, whatever happens treatment wise after that, we can say that January 30 injury is the cause. Is that accurate?
MR. NAGRICH: Same objection [Object to the form. It's leading and its already been answered].
THE WITNESS:
A. Yes, and I -- besides the fact that we have objective evidence of an injury.
(Ex. 1, 19).
Dr. Mullins rated the left shoulder due to the injury on January 30, 2017, to be 40 percent. He opined that Claimant had been temporarily and totally disabled from August 1, 2017 through October 1, 2017. He recommended no further care for the shoulder other than monitoring by his surgeon. On cross-examination, Dr. Mullins admitted that most shoulder replacements are due to degeneration and not necessarily traumatic. He admitted that he did not review the actual MRI but read the report which revealed severe degenerative changes in the left shoulder.
Credibility Findings
Having reviewed the whole record, I find that the opinions of Dr. Ted Lennard and that of Dr. John Putnam - the only orthopedic surgeon to render an opinion in this case - to be credible and more persuasive than the causation opinion of Dr. Mitchell Mullins.
CONCLUSIONS OF LAW
Section 287.020.2 RSMo, defines accident as an unexpected traumatic event or unusual strain identifiable by time and place of occurrence and producing at the time objective symptoms of an injury caused by a specific event during a single work shift. An injury is not compensable merely because the work incident was a triggering or precipitating factor. Rather, for an injury to be compensable under the Missouri Workers' Compensation Law, it must occur in the course of the individual's employment. An injury arises out of the course and scope of employment when a) it is reasonably apparent that the accident is the prevailing factor in causing the injury, and b) the injury does not come from a hazard or risk unrelated to employment to which workers would have been equally exposed in normal nonemployment life. § 287.020.3(2) (a) and (b) RSMo; Wilkins v. Piramal Glass USA, Inc., 540 S.W.3d 891, 895 (Mo. App. E.D. 2018). The prevailing factor means the primary factor in relation to any other factor. Id. The determination of whether an accident is "the prevailing factor" is inherently a factual one. Malam v. State
of Missouri, 492 S.W.3d 926 (Mo. banc 2016). It long has been held that a Claimant in a workers' compensation case has the burden to prove all essential elements of his claim. Royal v. Advantica Rest. Grp., Inc., 194 S.W.3d 371, 376 (Mo. App. W.D. 2006). Medical causation not within the common knowledge of a lay person must be established by scientific or medical evidence showing the relationship between the complained-of condition and the asserted cause. Gordon v. City of Ellisville, 268 S.W.3d 454, 461 (Mo. App. E.D. 2008).
As noted in the above Findings of Fact, Dr. Mullins agreed in deposition that if Claimant was asymptomatic prior to the January 30, 2017, then whatever treatment occurred thereafter, coupled with the objective evidence, demonstrated that the January 30th injury was the cause. The problem is that the medical record of Dr. Wester suggests that Claimant was symptomatic prior to the work incident on January 30, 2017. Moreover, Dr. Mullins appears to rely heavily on chronology, but in a case requiring medical expertise, the mere chronology between an event and the complained of condition is not substantial evidence of causation. Royal v. Advantica Rest. Grp., Inc., 194 S.W.3d at 377. Further, even if the MR Arthrogram showed a tear in the shoulder, such fact does not mean it occurred from acute trauma as opposed to degeneration. Neither Dr. Lennard nor Dr. Putnam, an orthopedic surgeon who actually reviewed the MR Arthrogram, found any acute injury involving the left shoulder on January 30, 2017. The evidence of severe osteoarthritis and degeneration, however, is overwhelming.
This case is distinguishable from Tillotson v. St. Joseph Medical Center, 347 S.W.3d 511 (Mo. App. W.D 2011, in which the parties stipulated that Claimant had sustained an acute lateral meniscus injury as a result of a work related accident which meniscus injury required treatment. A menisectomy, however, would have been futile in resolving the injured employee's medical condition because of advanced arthritis. A total knee replacement was the only appropriate option. The case turned on whether Claimant needed to prove that the compensable injury (meniscal tear) was the prevailing factor necessitating the knee replacement. The Court disagreed with that approach and indicated that the injured worker need only prove that the treatment was reasonably required to cure and relieve her from the effects of the compensable injury.
Unlike Tillotson, there is no agreement among the experts that Claimant's alleged work injury even required treatment. Relying on the credible opinions of Dr. Lennard and Dr. Putnam, I find and conclude that the incident on January 30, 2017, was not the prevailing factor in causing both the resulting medical condition and disability. The treatment to the left shoulder by Dr. Wester - left shoulder arthroplasty - did not flow from any injury occurring on January 30, 2017. Claimant has not sustained his burden in proving the essential elements of his claim. Benefits are denied. In light of this determination, I do not address any of the other issues.
