The Morphological Changes Of The Musculoskeletal Lesions In The Knees Of Patients With KOA Were Observed By Musculoskeletal Ultrasound

Objective:To observe the thickness of soft tissue,tendon and ligament of knee joint in patients with knee osteoarthritis and healthy volunteers,and to observe the changes of ultrasound image and the influence on knee joint movement.Material and method:Healthy group: 20 healthy volunteers were all from Shenyang,Liaoning Province,from May 2018 to December 2018.They met the inclusion criteria of this experiment.There were no other leg diseases that affected the experiment,and they signed the written consent of the volunteers.KOA patients group: 20 KOA patients were all from 2018.5 to 2018.12 in the First Affiliated Hospital of Liaoning University of Traditional Chinese Medicine.The selected patients were all in accordance with the Western medicine diagnosis of knee osteoarthritis as grade II and III patients,and were screened by inclusion criteria and exclusion criteria.The patients with KOA were palpated,and the lesions of tendons were recorded and marked;the corresponding points of tendons of healthy volunteers were marked;the tendons and lesions of the knee joints of the healthy and KOA patients on the front,medial and lateral sides of the knee joints were examined by musculoskeletal ultrasonography.Firstly,the soft tissues of the tendons and lesions of the knee joints on the three sides of the knee joints and around the knee joints were examined at static state.The morphology of ligaments,tendons,bursa and articular cavity of knee joint were observed at the point of tendon node and nodal lesion.Then the morphological changes of tendon node and soft tissue at the point of nodal lesion in three aspects of knee joint of all healthy subjects and KOA patients were observed dynamically,and the movement function of knee joint was also observed at the point of tendon node and nodal lesion around the knee joint,as well as the changes of ligaments,tendons,bursa and articular cavity of knee joint.Does it matter? Observation indicators:(1)To observe the soft tissue thickness of the nodules at the volunteer's and KOA's markers under musculoskeletal ultrasound.(2)The thickness of tendons,calcification and normal tendon attachment were observed in the marker sites of volunteers and KOA patients under musculoskeletal ultrasound,and the effect of tendons on the surrounding soft tissue and knee joint was observed.(3)To observe whether there is effusion in the articular cavity of volunteers and KOA patients,the amount of effusion,and the effect on knee joint function under musculoskeletal ultrasound.(4)Muscle-bone ultrasound was used to observe the condition of hydrocele in the synovium of volunteers and KOA patients,the nature of hydrocele in the synovium,the shape of the synovium,and the effect of the synovium on the function of the surrounding soft tissue and knee joint under dynamic conditions.(5)The thickness and uniformity of ligaments at the joints of the volunteers and KOA patients were observed under musculoskeletal ultrasound.The calcification,the normal attachment of ligaments and the effect of dynamic ligaments on the function of the surrounding soft tissues and knee joints were observed.Results: 1.There was no significant difference in the soft tissue thickness between KOA group and healthy group in the static extension and flexion positions,and there was no significant difference in the value difference between the extension and flexion positions.2.To observe the patellar ligament thickness in KOA group and healthy group,the patellar ligament thickness in static extension position and flexion position was statistically significant(p < 0.05),and the difference between extension position and flexion position was statistically significant(p < 0.05).3.Observation of the two groups,the thickness of goose feet at the lesion site of the KOA group and the thickness of goose feet at the node of the healthy group were statistically tested in the static extension and flexion position,P < 0.05,with statistical significance;and the numerical difference between the extension position and the flexion position was statistically tested,p < 0.05,with statistical significance.4.Observing the two groups,the thickness of quadriceps femoris tendon in KOA group and healthy group was statistically significant in static extension and flexion position(p < 0.05),but the difference between extension and flexion position was statistically significant(p > 0.05).5.Observation of two groups,KOA patients in 20 cases,14 patients with suprapatellar bursa effusion belong to the normal range,6 patients with suprapatellar bursa effusion beyond the normal range,its effusion is between 5.8 ml-6.4 ml;20 healthy patients,suprapatellar bursa effusion are within the normal range.6.Observation of the two groups,20 cases of KOA patients,11 cases of knee joint effusion belong to the normal range,9 cases of knee joint effusion beyond the normal range;20 cases of healthy group,knee joint effusion are within the normal range.Conclusion: 1.There was no significant difference between the soft tissues at the tendon node of KOA patients and those of healthy volunteers.2.The function of knee joint movement in KOA patients is related to patellar ligament,goose foot and synovial effusion at the focal point of the tendon,and the patellar ligament and goose foot at the focal point of the tendon have a tendency of thickening.3.The quadriceps femoris tendon at the focus of KOA tendon is thicker than the quadriceps femoris tendon at the node of tendon in healthy volunteers,but there is little relationship between the knee joint motor function and quadriceps femoris tendon in KOA patients.
