ObjectiveTo investigate the effect and influence factors on knee joint peripheral fractures and/or dislocations with an associated vascular injury through retrospectively study.MethodsFrom March 2002 to November 2007 31 patients with knee joint peripheral fractures and/or dislocations with an associated vascular injury were treated, including 24 males and 7 females with a mean age of 41 years (range from 21 to 62 years). Definite diagnosis of vascular injury by combining colored ultrasonic, CTA, operative exploration with clinical signs, fixing fractures and/or dislocations with fixators, plates and screws, reconstructing blood circulation based on the condition of the vascular injury by vascular repair, homograft vein or artificial vascular grafting separately and analysing the effects of PSI, diagnosis and treatment methods on salvage lower extremities.ResultsSuccessful reconstruction was carried out in 31 cases, however there were 1 death because of mult-fractures and brain injury and 6 amputation, 24 cases successful salvage followed up mean 24.2 months, 6 cases bone nonunion and infected bone defect were cured by delayed bone planting or bone transportation. Ligaments repair reconstruction of 7 cases knee joint dislocation were done in delayed 3 or 4 weeks after first operation, the good functional rate was 71.4%.ConclusionsThe patients of PSI under 10 grades in knee joint peripheral fractures and/or dislocations with an associated vascular injury should been carried out treatment, early definite diagnosis and blood circulation reconstruction are the key factors of successful salvage treatment.
