a b s t r a c tPopliteal artery injury is a rare but known complication in knee surgery. Only one article in current literature reports that the risk increases during revision knee surgery. A new case is described in which an injury to the popliteal artery occurred during lateral unicompartmental to total knee arthroplasty revision surgery. This vascular injury occurred 5e10 cm below the tibial resection level in a healthy patient with a history of cruris fracture with plate osteosynthesis and lateral unicompartmental knee arthroplasty. This paper stresses the importance of being aware that trauma and surgery can create fibrosis in which the popliteal artery can get fixated, thus reducing the scope for safe manipulation of the knee during secondary surgery.Copyright ª 2013, Professor P K Surendran Memorial Education Foundation.

IntroductionVascular lesions of the popliteal artery are rare but have been described after total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), revision TKA, correction osteotomy procedures and dislocations of the knee. 1e9 Etiology can be thrombosis, direct trauma or indirect trauma. 3,6,7,10e16 Our case shows an indirect popliteal lesion 5 cm distal to the operation area in a patient during revision knee surgery and stresses the importance of meticulous surgery in order to prevent indirect trauma especially in cases in which fibrosis could be present due to prior surgery or trauma.
Case reportA fifty one year old healthy female was treated for lateral compartmental osteoarthritis of the right knee in another hospital. A lateral UKA was performed. Because of complaints on the lateral side of the knee she visited us two years after primary surgery. The diagnosis of tibial component overhang was made and revision surgery was planned. j o u r n a l o f o r t h o p a e d i c s 1 0 ( 2 0 1 3 ) 3 8 e4 0
