在临床研究中使用回顾性获得的术前AOFAS评分来评估择期足踝手术的结局尚未得到验证。利用这种方法获得的数据可能会歪曲结果，并导致虚假的结论。本研究比较了择期手术患者术前和术后的AOFAS踝关节-后足评分，以确定回顾性获得的评分是否与前瞻性收集的评分相匹配。47例患者中只有2例（4%）回忆起相同的AOFAS评分。术前评分之间的平均差异（术后获得的术前评分减去术前获得的术前评分）为-5.3分。15例患者（32%）的术前评分相差20分或更多。Kappa统计发现，当手术前后获得的反应相互比较时，组成两个术前评分的五个要素之间几乎没有一致性。结果表明，择期手术后获得的术前临床评分是一个穷人的病人的术前条件的预测和研究，采用回顾性获得术前AOFAS临床评分可能高估手术的好处。
The use of retrospectively acquired preoperative AOFAS rating scores in clinical research to assess the outcomes of elective foot and ankle surgery has not been validated. The data obtained utilizing this methodology may misrepresent the results and lead to spurious conclusions. This investigation compared preoperative AOFAS Ankle-Hindfoot scores obtained before and after surgery from patients who had undergone elective surgery to determine if retrospectively acquired scores match those collected prospectively.Only two out of 47 patients (4%) recalled identical AOFAS scores. The mean difference between the preoperative scores (preoperative score obtained after surgery minus preoperative score obtained before surgery) was -5.3 points. Fifteen patients (32%) had preoperative scores that differed by 20 points or more. Kappa statistics found little agreement among the five elements that comprised the two preoperative scores when responses obtained before and after surgery were compared to one another. The results suggest that preoperative clinical rating scores obtained after elective surgery are a poor predictor of the patient's preoperative condition and that studies which employ retrospectively acquired preoperative AOFAS clinical rating scores may overestimate the benefit of surgery.
