Ordered that the order is affirmed, with costs.
The defendant failed to establish, prima facie, that the plaintiff did not sustain a serious injury within the meaning of Insurance Law § 5102 (d) as a result of the subject accident ( see Toure v Avis Rent A Car Sys., 98 NY2d 345; Gaddy v Eyler, 79 NY2d 955, 956-957). The defendant failed to even address, much less satisfy, his burden with respect to the plaintiff's allegation that he suffered a knee injury as a result of the accident ( see Hughes v Cai, 31 AD3d 385; Loadholt v New York City Tr. Auth., 12 AD3d 352). Since the defendant failed to establish his prima facie entitlement to judgment as a matter of law in the first instance, it is unnecessary to reach the question of whether the plaintiff's papers were sufficient to raise a triable issue of fact ( see Coscia v 938 Trading Corp., 283 AD2d 538).
