Abstract: Objective To investigate the clinical significance about the severity of trauma to the affected limb caused by popliteal artery injury at different levels, to evaluate the role of sural artery in repair of popliteal artery trauma. Methods One hundred and three patients with unilateral knee fracture (dislocation) who were admitted to our hospital from January 2010 to December 2019 were collected. Sixty-eight patients with popliteal artery injury were divided into a high group (n=16) and a low group (n=52) according to whether the injury level was higher than the sural artery or not, the remaining 35 patients were in a control group. The CK (creatine kinase) of three groups before operation and 1 day, 3 days, 7days, 15 days after operation were compared and analyzed. Results CK value in the high group was significantly higher than that in the low group, while the low group was higher than the control group (F=217.709, P<0.001). There were significant differences in CK value among the three groups at the same time point (before operation, 1 day, 3 days, 7 days 15 days after operation) (P<0.001). There were statistical differences in CK value at each time point in the high group (P<0.05); there were no statistical differences in CK value between before operation and 7 days after operation (P=0.930), 1 day and 3 days after operation (P=0.195) in the low group. Conclusions The degree of limb ischemia and injury  in the high group is more serious than that in the low group. The sural artery is the main reason for CK difference at different injury planes of popliteal artery, and it has a compensatory effect.
