Between December 2010 and November 2018, 24 patients were enrolled in this study. There were 16 males and eight females with an average age of 39.1 years and a follow-up period of 50.9 months. The clinical results were evaluated according to the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS) score. Pre-operative plain radiographs and magnetic resonance imaging (MRI) scans, post-operative radiographs, and X-ray and computed tomography (CT) scans at the last follow-up were observed.
There was a significant improvement in the AOFAS score from 61.3 ± 19.0 pre-operatively to 84.9 ± 9.2 post-operatively (P < 0.001). The VAS score improved from 6.1 ± 2.3 to 2.0 ± 1.4 at the last follow-up (P < 0.001). Twenty-one patients (87.5%) were satisfied with their clinical results. By the last follow-up CT scan, there was bone cyst formation at the donor sites in three patients, at the recipient sites in five patients and at both sites in five patients. Two patients (8.3%) underwent re-operation with arthroscopic debridement because of medial gutter hypertrophic soft tissue impingement.
OAT harvesting from the ipsilateral talar articular facet showed satisfactory results. The mean post-operative VAS score and AOFAS ankle-hindfoot score improved significantly. Post-operative impingement around the osteotomy site was the main complication and reason for re-operation after the index procedure. In addition, bone cysts at the recipient and/or donor site(s) were found with a large percentage under CT. Therefore, longer follow-up is necessary to determine the long-term clinical results for this technique.
2010年12月至2018年11月,24名患者被纳入本研究。男性16例,女性8例,平均年龄39.1岁,随访时间50.9个月。根据美国骨科足踝协会(AOFAS)踝足-后足评分和视觉模拟评分(VAS)评分对临床结果进行评估。术前平片和磁共振成像(MRI)扫描,术后X光片,最后随访时进行X线和计算机断层扫描(CT)扫描。
AOFAS评分从术前61.3±19.0显著改善至术后84.9±9.2(P<0.001)。末次随访时VAS评分由6.1±2.3提高至2.0±1.4(P<0.001)。21例患者(87.5%)对其临床结果感到满意。最后一次CT扫描,三名患者的供体部位有骨囊肿形成,五名患者的受体部位和五名患者的两个部位。两名患者(8.3%)由于内侧沟肥厚性软组织撞击而接受了关节镜清理术的再次手术。
从同侧距骨关节小关节收获OAT显示令人满意的结果。术后平均VAS评分和AOFAS踝足-后足评分明显改善。术后截骨部位周围撞击是索引程序后再次手术的主要并发症和原因。此外,在CT下发现受体和/或供体部位的骨囊肿有很大比例。因此,需要更长时间的随访才能确定该技术的长期临床结果.
