Preliminary study to evaluate early musculoskeletal injury by using shear wave elastography
Objective To evaluate feasibility of early skeletal muscle injury by using shear wave elastography.Methods Sixty patients with unilateral knee osteoarthritis treated in Department of Orthopedics of People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from May 2020 to January 2021 were selected as the research subjects.Conventional scanning and shear wave elastography techniques were applied to investigate affected and healthy knees.Measurement included cartilage morphology,thickness and damage,joint cavity effusion,synovial membrane thickness,ligament morphology,meniscus protrusion degree,and detection of shear wave values in attachment area of quadriceps tendon on patella.Thickness and shear wave values of tendons in different observation areas on affected side and healthy side were compared.Affected knee joint was assigned a value based on the ultrasound characteristics,and Spearman correlation was used to analyze correlation between ultrasound score and shear wave value.Results Among 60 patients,fifty-six cases(56/60,93.3%)of cartilage injury in knee joint,30 cases(30/60,50.0%)of synovial hyperplasia in knee joint,35 cases(35/60,53.3%)of medial meniscus extrusion in knee joint,57 cases(57/60,95.0%)of effusion in knee joint cavity,21 cases(21/60,35%)of osteophyte formation in knee joint,and zero case of popliteal cyst in knee joint.There were 34 cases with ultrasound score less than three points,26 cases with score three to seven points,and zero case with score more than seven points.Shear wave value of the tendon in affected lateral area was significantly greater than that in affected medial area(P<0.01).Shear wave value of tendon in healthy medial area was significantly higher than that in affected medial area(P<0.01).Shear wave value of quadriceps tendon decreases with increase of ultrasound score,showed a high correlation(r=0.955,P<0.01).Conclusion Shear wave elastography is a non-invasive and relatively easy-to-operate method for evaluating muscle injury,which is highly correlated with severity of knee osteoarthritis,can help detect early strain points,providing possibilities for grading and diagnosis of knee osteoarthritis.
