Abstract：
UNASSIGNED: Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm2. However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus.
UNASSIGNED: Patients were randomly enrolled into two groups. At three weeks postoperatively, the rESWT group was given shockwave treatment, once every other day, for five treatments. In the control group the head of the device which delivered the treatment had no energy output. The two groups were evaluated before surgery and at six weeks and three, six and 12 months postoperatively. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Secondary outcome measures included a visual analogue scale (VAS) score for pain and the area of bone marrow oedema of the talus as identified on sagittal fat suppression sequence MRI scans.
UNASSIGNED: A total of 40 patients were enrolled and randomly divided into the two groups, with 20 in each. There was no statistically significant difference in the baseline characteristics of the groups. No complications, such as wound infection or neurovascular injury, were found during follow-up of 12 months. The mean AOFAS scores in the rESWT group were significantly higher than those in the control group at three, six, and 12 months postoperatively (p < 0.05). The mean VAS pain scores in the rESWT group were also significantly lower than those in the control group at these times (p < 0.05). The mean area of bone marrow oedema in the rESWT group was significantly smaller at six and 12 months than in the control group at these times (p < 0.05).
UNASSIGNED: Local shockwave therapy was safe and effective in patients with osteochondiritis of the talus who were treated with a combination of arthroscopic surgery and rESWT. Preliminary results showed that, compared with arthroscopic microfracture alone, those treated with arthroscopic microfracture combined with rESWT had better relief of pain at three months postoperatively and improved weightbearing and motor function of the ankle.

摘要：
■关节镜下微骨折是距骨软骨炎患者的常规治疗形式，涉及<1.5cm2的面积。然而,一些患者在术后早期有持续性疼痛和活动受限。没有研究对这些患者进行微骨折和短波治疗的联合治疗。这个潜在的单一中心的目标，随机化，双盲,安慰剂对照试验是比较关节镜下微骨折联合放射状体外冲击波治疗（rESWT）和单纯关节镜下微骨折治疗患者的结局，患有距骨骨膜炎的患者。
■患者随机分为两组。术后三周，rESWT组给予冲击波治疗,每隔一天,五次治疗。在对照组中,递送治疗的装置的头部没有能量输出。两组分别于手术前、手术6周和3周进行评估,术后6个月和12个月。主要结果指标是美国骨科足踝协会（AOFAS）踝足-足量表。次要结果指标包括疼痛的视觉模拟评分（VAS）评分以及矢状脂肪抑制序列MRI扫描中确定的距骨骨髓水肿面积。
■共纳入40例患者，随机分为两组，每个都有20个。各组的基线特征无统计学差异。无并发症,如伤口感染或神经血管损伤，在12个月的随访中发现。rESWT组的平均AOFAS评分明显高于对照组,六,术后12个月（p<0.05）。此时rESWT组的平均VAS疼痛评分也显著低于对照组(p<0.05)。rESWT组在6个月和12个月时的平均骨髓水肿面积明显小于对照组(p<0.05)。
■在关节镜手术和rESWT联合治疗的距骨软骨炎患者中，局部冲击波治疗是安全有效的。初步结果表明,与单独的关节镜微骨折相比，关节镜下微骨折联合rESWT治疗的患者在术后3个月时可更好地缓解疼痛,并改善踝关节的承重和运动功能.
