the Court elaborated that “consistent with this observation, neither the statute nor the Board’s guidelines lists the ankle or the knee as body parts lending themselves to separate SLU awards. Rather, impairments to these extremities are encompassed by awards for the loss of use of the leg (see Workers’ Compensation Law § 15[3][b]; New York State Guidelines for Determining Permanent Impairment and Loss of Wage Earning Capacity § 8, at 43 [2012]).” For that reason, The Court determined the Board properly deducted prior schedules for the claimant’s right knee and ankle to arrive at the claimant’s overall schedule loss of use of the right leg.
