        • Effect of ultrasound-guided intra-articular injection of platelet-rich plasma in the treatment of osteonecrosis of the femoral head: a retrospective study

          ObjectiveTo explore the clinical efficacy and safety of ultrasound-guided intra-articular injection of platelet-rich plasma (PRP) in the treatment of avascular necrosis of the femoral head.MethodsWe retrospectively collected and analyzed the clinical characteristics, imaging data, and clinical outcomes of patients with femoral head necrosis who received ultrasound-guided intra-articular PRP injection in the Department of Rehabilitation Medicine of Sun Yat-sen Memorial Hospital, Sun Yat-sen University between June 2019 and June 2020. All the patients received 4 injections at one-week intervals. The Visual Analogue Scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Harris Hip Joint Function Scale (HHS) were evaluated before treatment and 1 month, 3 months, and 6 months after the first injections. Adverse events were recorded. The normally distributed data were presented as mean±standard deviation, and analyzed by one-way repeated measures analysis of variance; the non-normally distributed data were presented as median (lower quartile, upper quartile), and analyzed by Friedman test.ResultsA total of 29 patients were included. According to the Association Research Circulation Osseous classification standard, 2 patients were classified as stageⅠ, 11 as stageⅡ, 11 as stage Ⅲ, and 5 as stage Ⅳ. Before treatment and 1 month, 3 months, and 6 months after treatment, the VAS scores were 7.0 (5.5, 8.0), 4.0 (3.0, 5.0), 3.0 (2.0, 3.0), and 3.0 (2.0, 5.0), respectively, the WOMAC scores were 39.27±11.70, 28.34±8.08, 22.82±6.09, and 24.13±7.55, respectively, and the HHS were 46.0 (40.0, 64.0), 71.0 (57.5, 75.0), 78.0 (68.0, 80.5), and 78.0 (64.0, 80.0), respectively. The time effects in VAS (χ2=65.423, P<0.001), WOMAC (F=46.710, P<0.001), and HHS (χ2=66.347, P<0.001) were all statistically significant. There were significant differences in each index between the values 1 month, 3 months, and 6 months after treatment and those before treatment respectively, and there was also a significant difference in each index between the value 1 month after treatment and that 3 months after treatment (P<0.05). There was no significant difference in any indicator between the value 6 months after treatment and that 3 months after treatment (P>0.05). Significant difference was shown between the value 6 months after treatment and that 1 month after treatment in WOMAC (P=0.016), but not in VAS or HHS (P>0.05). No obvious adverse event was reported during the follow-up period.ConclusionsUltrasound-guided intra-articular PRP injection can effectively alleviate the pain and improve the hip joint function of patients with femoral head necrosis for at least 6 months. However, randomized controlled studies with a larger sample size and longer-term follow-up are needed in the future to confirm the efficacy and safety of PRP injection in femoral head necrosis.

          ObjectiveTo explore the clinical efficacy of ultrasound debridement combined with autolytic debridement in the treatment of diabetic foot ulcers.MethodsA total of 60 diabetic foot ulcers patients who were diagnosed and treated in Jinshan Hospital of Fudan University from April 2019 to April 2020 were enrolled in the study and randomly divided into two groups, with 30 cases in each group. The trial group received autolytic cleansing combined with ultrasound debridement treatment, and the control group only received autolytic debridement treatment. The baseline conditions, wound treatment efficacy, number of dressing changes, length of hospital stay, treatment cost, wound healing time, wound shrinkage rate, and the time required for the wound to turn into 100% red granulation were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, duration of diabetes or Wagner grade of diabetic foot between the two groups (P>0.05). The efficacy of wound healing in the trial group was better than that in the control group (Z=?2.146, P=0.032). The number of dressing changes [(11.76±2.23) vs. (17.34±4.43) times] and the length of stay [(18.03±3.73) vs. (25.43±4.43) d] in the trial group were lower than those in the control group, and the differences were statistically significant (P<0.05). The difference in treatment cost between the two groups was not statistically significant (P>0.05). The wound healing time of the trial group [(48.43±18.34) vs. (65.24±19.62) d], the wound shrinkage rate [(78.35±8.34)% vs. (56.53±6.54)%] and the time required for the wound to turn into 100% red granulation [(16.34±2.42) vs. (24.55±3.23) d] were better than those of the control group, and the differences were statistically significant (P<0.05). During the treatment process, no patient in the trial group had wound bleeding and had difficulty in stopping bleeding during ultrasonic debridement, and no patient had intolerable pain related to ultrasonic debridement. No patients in either group withdrew early.ConclusionsUltrasound debridement combined with autolytic debridement can effectively improve the curative effect of patients with diabetic foot ulcers and shorten the wound healing time. Therefore, it is worthy of promotion and application in the wound care of patients with diabetic foot ulcers.
