Abstract:Objective To investigate the clinical diagnostic value of musculoskeletal ultrasound in the diagnosis of senile degenerative knee joint lesions.Methods Sixty patients (87 knees) with degenerative knee arthropathy were selected.All knees were examined by musculoskeletal ultrasound,MRI and arthroscopic surgery.The clinical value of musculoskeletal ultrasound in the diagnosis of degenerative knee joint disease was analyzed by comparing the results of ultrasound and MRI examination of knee joint with the diagnosis after arthroscopic surgery.Results Musculoskeletal ultrasound could clearly show articular cartilage lesions,synovial thickening and joint effusion,and the abundance of blood flow signals in proliferative synovium.There was no significant difference between ultrasound and MRI in diagnostic coincidence rate (P>0.05).However,for the diagnosis of tendon,meniscus and ligament injuries,MRI was significantly better than musculoskeletal ultrasound,the difference was statistically significant (P<0.05).Conclusion The diagnostic value of musculoskeletal ultrasound for early degenerative knee joint lesions is the same as that of MRI.It canbe used as a routine examination of knee joint diseases in middleaged and elderly people,and is worthy of clinical application.
