Abstract：
OBJECTIVE: This study aims to compare the mid-term functional outcomes of microfracture and mosaicplasty techniques in talus osteochondral lesions.
METHODS: This study consists of 47 patients with talus osteochondral lesions who underwent arthroscopic surgery. These patients were divided into two groups: microfracture (28 patients) and mosaicplasty (19 patients). The American Orthopedic Foot and Ankle Society (AOFAS) scoring system was used to evaluate ankle function, and the Visual Analog Scale (VAS) score was used for pain assessment.
RESULTS: The mean follow-up period was 26 months (range 10-36 months). It was determined that the mean preoperative AOFAS score of individuals in the mosaicplasty group was 38.84±2.83, and the postoperative AOFAS score was 78.79±3.91. A statistically significant difference was found between the two measurements of AOFAS scores (preoperative and postoperative) in the mosaicplasty group (*t=33.756; p<0.001). The effect size for this difference observed in the mosaicplasty group was determined to be r=0.992 (large). Similarly, a statistically significant difference was found between the two measurements of AOFAS scores (preoperative and postoperative) in the microfracture group (*t=28.152; p<0.001). The effect size for this difference observed in the microfracture group was determined to be r=0.983 (large).
CONCLUSIONS: We believe that both treatment methods have similar positive effects on pain and ankle function. However, larger controlled studies with longer follow-up periods are needed to reach a definitive conclusion.

摘要：
目的：本研究旨在比较距骨骨软骨损伤中微骨折和镶嵌成形技术的中期功能结局。
方法：本研究包括47例接受关节镜手术的距骨软骨损伤患者。这些患者分为两组：微骨折（28例）和马赛克成形术（19例）。美国骨科足踝协会(AOFAS)评分系统用于评估踝关节功能,疼痛评估采用视觉模拟量表(VAS)评分。
结果：平均随访期为26个月（范围10-36个月）。经测定,镶嵌成形组个体术前AOFAS评分平均为38.84±2.83分,术后AOFAS评分为78.79±3.91分。在镶嵌术组中，AOFAS评分的两种测量值（术前和术后）之间存在统计学上的显着差异（*t=33.756；p<0.001）。在镶嵌成形术组中观察到的这种差异的效应大小被确定为r=0.992(大)。同样，微骨折组的AOFAS评分的两项测量值(术前和术后)之间存在统计学上的显著差异(*t=28.152;p<0.001).在微骨折组中观察到的这种差异的效应大小被确定为r=0.983(大)。
结论：我们认为两种治疗方法对疼痛和踝关节功能具有相似的积极作用。然而,需要更大的对照研究和更长的随访时间才能得出明确的结论.
