   MEMORANDUM

Byron Eugene Johnson, a California state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his 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 Johnson failed to raise a genuine dispute of material fact as to whether defendants were deliberately indifferent to his knee and leg problems. See id. at 1057-58 (a prison official acts with deliberate indifference only if he or she knows of and disregards an excessive risk to the prisoner’s health and safety; negligence and a mere difference in medical opinion are insufficient); Taylor v. List, 880 F.2d 1040, 1045 (9th Cir.1989) (“Liability under section 1983 arises only upon a showing of personal participation by the defendant.”).

Johnson’s remaining contentions are unpersuasive.

AFFIRMED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by 9 th Cir. R. 36-3.
