Finding that Uhlenhake failed to establish a connection between the knee injury and a compensable event, the court upheld the denial of workers’ compensation for injury to his left knee. Uhlenhake’s ability to recover would have been enhanced if he had provided timely notice of the injury. Generally, an injured employee must provide timely notice to his or her employer and file a claim within the time frame established by the relevant workers’ compensation statute. See Pittsburgh Steelers Sports, Inc. v. Workers’ Comp. Appeal Bd., 814 A.2d 788 (Pa. Commw. Ct. 2002) (notification of injury given to team trainer is sufficient to meet statutory notice requirements for workers’ compensation).
