We deem the issue of medical causation to be dispositive. Employee alleges that an accident or occupational exposure caused her to suffer an injury occurring or culminating on or about September 9, 2009.
Section 287.020.3(1) RSMo provides, in relevant part, as follows:
An injury by accident is compensable only if the accident was the prevailing factor in causing both the resulting medical condition and disability. "The prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability.
Section 287.067.2 RSMo provides, in relevant part, as follows:
An injury by occupational disease is compensable only if the occupational exposure was the prevailing factor in causing both the resulting medical condition and disability. The "prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability. Ordinary, gradual deterioration, or progressive degeneration of the body caused by aging or by the normal activities of day-to-day living shall not be compensable.

[^0]: ${ }^{2}$ We note that it is somewhat unclear from employee's multiple claims for compensation (combined with her rather confused and contradictory testimony at the hearing before the administrative law judge) which of her claimed injuries correlate to this claim for compensation. However, at oral argument in this matter, employee's counsel made clear that this claim does not include the total knee replacements.
We have found that employee did not suffer any medical condition or disability as a result of any accident or occupational disease occurring or culminating on or about September 9, 2009. We conclude that the claimed accident and/or occupational exposure are not the prevailing factor causing employee to suffer any identifiable medical condition or disability.
