Abstract Lower limb malalignment around the knee may be a risk factor of knee osteoarthritis (OA) progression. A surgical treatment method for preventing OA progression is osteotomy and one of the rare side effects of this surgery is injury to the arteries. We present three cases, two men (24 and 42 years old) and one woman (15 years old) who were diagnosed with lower limb malalignment and received high tibial or distal femoral osteotomies and were complicated with arterial injury. Delay in diagnosis of the injury varied from about an hour to about one month after surgery.
