   MEMORANDUM

California state prisoner Steven Gonzales appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1988 action alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir.2004), and we affirm.

The district court properly granted summary judgment because Gonzales failed to raise a genuine- dispute of material fact as to whether Dr. Ugwueze was deliberately indifferent to Gonzales’s knee pain. See id. at 1057-60 (a prison official acts with deliberate indifference only if he or she knows of and disregards an excessive risk to a prisoner’s health; a mere difference in opinion between a prisoner and a physician concerning the appropriate course of treatment is insufficient); see also McGuckin v. Smith, 974 F.2d 1050, 1060 (9th Cir.1992), overruled on other grounds by WMX Techs., Inc. v. Miller, 104 F.3d 1133 (9th Cir.1997) (en banc) (“A defendant must purposefully ignore or fail to respond to a prisoner’s pain or possible medical need in order for deliberate indifference to be established.”).

The district court did not abuse its discretion in denying Gonzales’s motion for appointment of an expert witness because Gonzales’s deliberate indifference claim was neither factually nor legally complex. See Walker v. Am. Home Shield Long Term Disability Plan, 180 F.3d 1065, 1070-71 (9th Cir.1999) (setting forth standard of review).

AFFIRMED.
