The Elderly Knee Osteoarthritis Soft Tissue Ultrasonic Change And Preliminary Discussion Diabetes And Hypertension

Objective:To investigate the clinical significance of ultrasonography for the elderly with degenerative knee cartilage. Methods:Totally 171 patients who were≥60 years old and successively admitted for knee disease were selected and according to clinical diagnostic criteria of degenerative knee disease, divided into two grou-ps:osteoarthritis group (148 knees) and non-osteoarthritis group (163 knees). Above patients were divided into 4 groups by with/without diabetes and hypertension,where there were 58 cases in hypertension group (27 in KOA group, and 31 in non-KOA group),44 cases in diabetic group (21 in KOA group,23 in non-KOA group),37 cases in group with associated diabetes and hypertension (19 in KOA group,18 in nonKOA group), and 32 cases in group not associated diabetes and hypertension (13 in KOA group,19 in non-KOA group). Knee joints ultrasonography was given to the two groups, to measure the knee joint suprapatellar bursa and hydrops depth of both internal and external bursas, while observe the synovium, pannus, cartilage, episome, meniscus, etc. Results:Among the 311 knee joints,there were 267 knees presenting articular cartilage (148 in KOA group,119 in non-KOA group), with the degeneration rate of 85.85%; and for KOA group, there were 116 knees of hyperplasia of synovium, where 61 knees of them were formed with pannus, and148 knees of cartilage surface roughness,112 knees of cartilage thinning or losing,28 cases of meniscus protuberance and 17 knees of episome found in ar-ticular cavity. While, there were 58 knees of hyperplasia of synovium,101 knees of cartilage surface roughness and 17 knees of cartilage thinning in non-KOA group. Hydrops in articular cavity for KOA group was significantly more than that of non-KOA group, showing statistical difference (P<0.05). Once grouped by with/with out diabetes and/or hypertension, the difference between hydrops depths of articular cavity in KOA group was not statistically significant (P> 0.05), while as for the difference between hydrops depths of articular cavity, comparing with the group not associated diabetes and hypertension, the hypertension group as well as group with associated diabetes and hypertension were statistically significant (P<0.05). Conclusion:These findings indicate that ultrasonography is of certain clinical significance in evaluation of degenerative knee cartilage in the elderly.
