| Purpose:This study is to observe the common focal points and effusion on the knees of normal people and patents with knee osteoarthritis(KOA) by musculoskeletal ultrasound technology, and to preliminarily clarify the anatomical characteristics of tendons in lower limbs, establishing a standard location for tendons in lower limbs. Meanwhile, to create a new method for study on the essence of tendons, providing a solid foundation for the further study on tendons.Material and method:100 cases with KOA had been collected in this study from January 2013 to December 2014 in Liaoning University of Traditional Chinese Medicine Affiliated Hospital, 100 healthy volunteers had also been included. The number of male is 50, female is 50. Palpation examination had been used to find out the focal points both in patients and volunteers and marked them. Explored these focal points with the method of musculoskeletal ultrasound technology and observed the tissue thickness as well as effusion situation such as ligament.Results: 1 Comparison between knee osteoarthritis patients and healthy volunteers in basic conditions: the average age of the patients is 54.39±5.97, that of volunteers is 54.78±5.72, the weights of patients is 62.51 ± 6.89 Kg, that of volunteers is 64.9±7.05 Kg, the average circumference of thing among these patient is 530.8+52.2mm, that of volunteers is 520.8+59.1mm, there is no significant difference. 2 Circumference of knee Knee week: the average circumference of knee among patients is 414.1±56.7 mm, and that of volunteers is 383.0 ±53.7 mm, there is a significant difference between them; 3 The average width of quadriceps tendon, patellar tendon, lateral retinacular, medial collateral ligament, and lateral collateral ligament are respectively 0.80±0.12、0.33±0.08、0.39±0.11、0.39±0.09、0.82±0.08 mm they are larger than that of volunteers, P < 0.05, there is a significant difference; the width of medial collateral ligament among patients and volunteers are respectively 0.25± 0.10, 0.27± 0.08, there is no significant difference P > 0.05.4 The width of ligament among patients with Yang Ming muscle meridian injury is greater than that of volunteers, there is a significant difference, p<0.05; the width of lateral collateral ligament in patients with Foot Shaoyang muscle meridian injury is 0.835± 0.06 mm, that of volunteers is 0.565±0.08 mm, which is fewer than that in patients, there is a significant difference, P < 0.05; the width of medial collateral ligament in patients with Zu San yin muscle meridian injury is 0.392±0.068 mm, and that of volunteers is 0.361 ± 0.069 mm, there is a significant difference, p<0.05. 5 The number of patients with more than 2mm effusion in suprapatellar bursa, prepatellar bursa, deep infrapatellar bursa, patients with superficial bursa are respectively 63, 55, 42, 21; while that in volunteer group are respectively 11, 8, 5, and 2, there is a significant difference.Conclusion: 1 The hyperplasia degree of knee circumference and ligament is proportional to effusion, it reveals that MSUS examination is consistent with the manifestation of symptoms, so that MSUS can be regarded as a criteria for diagnosis of severity of KOA; 2 The width of ligaments in KOA patients is obviously larger that in volunteers, the pathological reactions is reflected from the inner knee structure, it presents that the injury degree of muscle tendons can be reflected by ligament hyperplasia and effusion. It also shows the accurate degree of MSUS. 3 Patients with the same muscle meridian injury, the corresponding ligament has a significant hyperplasia, indicating that there is a specificity between muscle meridian injury and its corresponding ligament. |
