Acute knee (tibiofemoral joint) dislocation is a serious knee injury, although population-based numbers and incidence rates of knee dislocation with or without concomitant vascular injury are unknown.
The study covered the whole adult population of 4 million persons (aged ≥ 18 years) in Finland during the 11-year period from January 1, 1998, to December 31, 2011. Data on hospitalization caused by acute knee dislocations and concomitant vascular injuries requiring operative treatment were obtained from the nationwide National Hospital Discharge Registry.
During the 14-year study period, a total of 837 patients with knee dislocation diagnosis were hospitalized in Finland. The highest incidence rates in men were in persons aged 18 years to 29 years (incidence, 29 per 1 million person-years in 2011), and the incidence decreased by age, while in women, this incidence was rather similar in all age groups. The most common injury mechanism of knee dislocation was low-energy fall at the same level (46%). The median length of hospital stay was 2 days (range, 1-109 days). In 107 cases (13%), knee dislocation required immediate open (69 cases) or closed (38 cases) reduction in the operating room. Popliteal artery injury requiring acute surgical intervention was found in 13 patients (1.6%), and amputation at the level above the tibiofemoral joint was performed for one patient (0.1%).
This is the first study describing the population-based incidence of acute knee dislocation. Men aged 18 years to 29 years had the highest incidence rates. Half of the injuries were low-energy trauma. Popliteal artery injury requiring surgical intervention was a rare concomitant injury, but when present, the injury required immediate surgical repair to avoid dramatic consequences.
Nationwide epidemiologic study, level I.
急性膝关节(胫股关节)脱位是一种严重的膝关节损伤,尽管膝关节脱位伴或不伴伴发血管损伤的人群数量和发病率尚不清楚。
本研究涵盖了 1998 年 1 月 1 日至 2011 年 12 月 31 日 11 年间芬兰的 400 万成年人整个人群。通过全国性的国家住院患者登记处获得了因急性膝关节脱位和需要手术治疗的伴发血管损伤而住院的数据。
在 14 年的研究期间,芬兰共有 837 例膝关节脱位患者住院治疗。男性的最高发病率为 18 至 29 岁人群(2011 年发病率为每 100 万人年 29 例),发病率随年龄下降,而女性各年龄段的发病率则相当相似。膝关节脱位最常见的损伤机制是低能量同等水平跌倒(46%)。住院中位数为 2 天(范围,1-109 天)。在 107 例(13%)患者中,膝关节脱位需要在手术室立即进行开放(69 例)或闭合(38 例)复位。发现 13 例(1.6%)患者需要急性手术干预的腘动脉损伤,1 例(0.1%)患者在胫股关节以上水平截肢。
这是首次描述基于人群的急性膝关节脱位发病率的研究。18 至 29 岁的男性发病率最高。一半的损伤是低能量创伤。需要手术干预的腘动脉损伤是一种罕见的伴发损伤,但当存在时,损伤需要立即进行手术修复,以避免严重后果。
