Abstract：Objective To study the relevant factors of knee injuries caused by physical training at high altitudes in recruits of one armed police troop and provide a theoretical basis for reducing the incidence of knee injuries.Methods 180 recruits from different altitudes were examined with magnetic resonance imaging(MRI) of right knee in the first three months of training,and the lesions of bone marrow,meniscus,ligaments and articular cavity in different phases were compared.Results (1)Recruits' knee injuries do not modify associations between whether participate in physical exercise or not before enlistment and weight categorizations for each training phase do not significantly impact knee quality,meniscus,ligaments and articular damage (P>0.05).(2)The incidence of recruits' bone marrow edema and articular effusion of low altitude group in the first and second phase were higher than those of high altitude group (P<0.05);The incidence of recruits' meniscal injury of low altitude group in the second and third phase were higher than those of high altitude group (P<0.05); The differences of the detectable rate of both groups' ligaments injury in different stages and bone marrow edema and articular effusion of the third phase were not statistically significant (P>0.05).Conclusions It is necessary to formulate the right protective measures and scientific strategies to reduce knee injuries.
