Abstract: Objective To discuss the diagnostic value of high frequency ultrasound on lesions of knee traumas.Methods Ninty-eight cases with post-traumatic knee injuries were examined by high frequency ultrasound,and the characteristics of changing ultrasonogram were observed and comparing with surgical results and MR.Results Of the 98 cases with post-traumatic knee injuries,there were 57 cases with effusion and hematocele in knee joint,among which there were 41 cases with collateral ligaments and meniscus injuries,the diagnostic coincidence rate was 93.3% in tendon tear and complete tendon fracture(compared with MR),91.7% in partial and complete muscle tear(compared with MR),67.7% and 71.4% in collateral ligaments and meniscus injuries(compared with surgical results).Conclusions High frequency ultrasound can be used as a conventional imaging examination method for post-traumatic knee injuries.
