Abstract：
UNASSIGNED: Whether arthroscopic microfracture is effective in treating cystic osteochondral lesions of the talus (OLTs) remains controversial. In this study, outcome parameters in patients with small and shallow subchondral cysts are compared to patients without cysts with the hypothesis that equivalent outcomes may be found after primary microfracture treatment.
UNASSIGNED: From 2018 to 2021, all 50 OLTs treated with arthroscopic microfracture in the authors\' hospital were retrospectively reviewed for eligibility. Single unilateral symptomatic lesions were included and divided into the cyst and noncyst groups, whereas kissing lesions and arthritic lesions were excluded. Numeric rating scale (NRS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores, Tegner activity level scores, Foot and Ankle Ability Measure (FAAM) scores, and magnetic resonance (MR) imaging results were used to describe outcomes.
UNASSIGNED: A total of 35 patients were included, 16 in the cyst group and 19 in the noncyst group. The patient characteristics were similar between the 2 groups (P > .05). In the cyst group the average cysts depth was 5.0 ± 1.3 mm. After a mean follow-up duration of 36.2 ± 10.2 months, no significant differences were found between the 2 groups in NRS, AOFAS, FAAM, or Tegner score improvement (P > .05). Three patients (19%) in the cyst group had no NRS score improvement.
UNASSIGNED: OLTs with small and shallow subchondral cysts can be treated with arthroscopic microfracture and achieve similar outcomes as noncystic lesions. A few cystic lesions may not respond to microfracture treatment.
UNASSIGNED: Level III, retrospective comparative study.

摘要：
■关节镜下微骨折治疗距骨（OLTs）囊性骨软骨损伤是否有效仍存在争议。在这项研究中,我们将小的和浅的软骨下囊肿患者的结局参数与无囊肿患者的结局参数进行了比较,假设在初次微骨折治疗后可以发现相同的结局.
■从2018年到2021年，对作者医院接受关节镜微骨折治疗的所有50例OLT进行了回顾性审查。包括单个单侧有症状的病变，并分为囊肿组和非囊肿组，而亲吻性病变和关节炎性病变被排除。数字评定量表（NRS）得分，美国骨科足踝协会（AOFAS）踝足-后足评分，Tegner活动等级得分,足踝能力测量（FAAM）评分，磁共振(MR)成像结果用于描述结局.
■共纳入35名患者，囊肿组16例，非囊肿组19例。两组患者特征相似(P>.05)。在囊肿组中，平均囊肿深度为5.0±1.3mm。平均随访时间为36.2±10.2个月，两组NRS无显著差异,AOFAS,FAAM,或Tegner评分改善（P>.05）。囊肿组3例(19%)NRS评分无改善。
■OLT伴软骨下小囊肿和浅性囊肿可通过关节镜微骨折治疗，并可获得与非囊性病变相似的结果。一些囊性病变可能对微骨折治疗没有反应。
■三级,回顾性比较研究。
