目的:本研究旨在比较距骨骨裂(TOPIC)治疗距骨内侧骨软骨损伤(OLT)后5或6周非负重后1年随访的临床结果和安全性。
方法:对接受内踝截骨TOPIC手术的前瞻性随访患者进行回顾性病例对照分析。两组患者均为5或6周非负重组。在步行过程中使用数字评定量表(NRS)评估临床结果,休息,跑步,和爬楼梯。此外,评估了足踝结局评分(FAOS)和美国骨科足踝协会(AOFAS)踝足-后足评分.此外,评估了放射学和并发症.
结果:11例患者纳入5周非负重组,22例患者纳入6周非负重组。在任何基线变量中没有发现显著差异。5周组步行期间的NRS提高了3.5分,6周组提高了4分(术后1年p=0.58)。此外,所有其他NRS分数,FAOS量表和AOFAS评分均有所改善(随访1年时均为n.s.)。在放射学(截骨愈合和移植物中存在囊肿)方面没有发现显着差异。此外,在并发症和再次手术方面没有发现显著差异.
结论:在临床,在非负重5或6周之间的放射学和安全性结果对于中间型OLT进行TOPIC。
方法:三级,治疗性。
OBJECTIVE: The present study aimed to compare the clinical outcomes and safety at a 1-year follow-up after 5 or 6 weeks of non-weight bearing after a Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC) for a medial osteochondral lesion of the talus (OLT).
METHODS: A retrospective comparative case-control analysis of prospectively followed patients who underwent a TOPIC procedure with medial malleolus osteotomy was performed. Patients were matched in two groups with either 5 or 6 weeks of non-weight bearing. Clinical outcomes were evaluated using the Numeric Rating Scale (NRS) during walking, rest, running, and stairclimbing. Additionally, the Foot and Ankle Outcome Score (FAOS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were assessed. Moreover, radiology and complications were assessed.
RESULTS: Eleven patients were included in the 5-week non-weight bearing group and 22 in the 6-week non-weight bearing group. No significant differences were found in any of the baseline variables. The NRS during walking in the 5-week group improved by 3.5 points and 4 points for the 6-week group (p = 0.58 at 1-year post-operatively). In addition, all other NRS scores, FAOS subscales and the AOFAS scores improved (all n.s. at 1 year follow-up). No significant differences in radiological (osteotomy union and cyst presence in the graft) were found. Moreover, no significant differences were found in terms of complications and reoperations.
CONCLUSIONS: No statistical significant differences were found in terms of clinical, radiological and safety outcomes between 5 or 6 weeks of non-weight bearing following a TOPIC for a medial OLT.
METHODS: Level III, Therapeutic.
