A prospective clinical study of the results of prosthetic ligament replacement of the ACL with the Gore-Tex polytetrafluoroethylene prosthesis was undertaken. Thirty-three (80%) of 41 patients were available at a minimum 36 month followup (mean, 48 months; range, 36 to 62). Kaplan-Meier survival analysis revealed an 82% probability of survival of the polytetrafluoroethylene ligament at the 48 month followup. When compared to the same data at a minimum 24 month followup, the results appeared to have deteriorated somewhat over time. Three possible "predictors" of failure at later followup were identified: preoperative subjective symptoms of swelling, subjective symptoms of giving way at 2 years, and an increased anterior drawer sign at 2 years.
对采用戈尔泰克斯聚四氟乙烯假体进行前交叉韧带假体置换的结果进行了一项前瞻性临床研究。41例患者中有33例（80%）至少随访了36个月（平均48个月；范围36至62个月）。Kaplan-Meier生存分析显示，在48个月随访时聚四氟乙烯韧带的生存概率为82%。与至少24个月随访时的相同数据相比，结果似乎随时间有所恶化。确定了后期随访失败的三个可能“预测因素”：术前肿胀的主观症状、2年时打软腿的主观症状以及2年时前抽屉试验阳性增加。
