This study investigated the clinical outcomes and mid- to long-term survival rates in patients undergoing transtibial pullout repair of medial meniscus posterior root tears (MMPRTs) after a minimum follow-up of 5 years.
Between 2005 and 2011, patients with MMPRTs who had been followed for at least 5 years after undergoing transtibial pullout repair were recruited. Participants were identified using medical records and information in a prospectively collected database. Clinical outcomes were assessed based on a comparison of patient preoperative Lysholm scores and their scores at the final follow-up. A Kaplan-Meier survival analysis was used to investigate the survival rates of repair procedures. Clinical failures were defined as cases requiring conversion to total knee arthroplasty (TKA) or having final Lysholm score <65 or less than their preoperative scores.
Overall, 91 patients (mean age, 58.7 ± 9.7 years) were included: the mean follow-up duration was 84.8 ± 13.8 months. Among these patients, the mean Lysholm score improved significantly from 51.8 ± 7.9 preoperatively to 83.0 ± 11.1 at the final follow-up (P < .001). Overall, 4 patients failed due to conversion to TKA (n = 1) or having final Lysholm scores <65 or less than the preoperative scores (n = 3). The overall Kaplan-Meier probabilities of survival after repair were 99% at 5 years, 98% at 6 years, 95% at 7 years, and 92% at 8 years.
Among patients with MMPRTs, transtibial pullout repair demonstrated a high clinical survival rate and the patients demonstrated clinical improvement, based on mid- and long-term follow-up examinations.
Level IV, retrospective uncontrolled case series.
本研究旨在探讨至少随访 5 年的胫骨结节内移术治疗内侧半月板后根部撕裂（MMPRT）患者的临床结果和中-长期生存率。
2005 年至 2011 年间，我们招募了接受胫骨结节内移术治疗且至少随访 5 年的 MMPRT 患者。通过病历和前瞻性收集的数据库中的信息来确定参与者。根据患者术前 Lysholm 评分与其最终随访时的评分比较来评估临床结果。采用 Kaplan-Meier 生存分析来研究修复术的生存率。临床失败定义为需要转换为全膝关节置换术（TKA）或最终 Lysholm 评分<65 或低于术前评分的病例。
共有 91 例患者（平均年龄 58.7±9.7 岁）纳入本研究：平均随访时间为 84.8±13.8 个月。在这些患者中，Lysholm 评分从术前的 51.8±7.9 显著改善至最终随访时的 83.0±11.1（P<0.001）。总体而言，有 4 例患者因转换为 TKA（n=1）或最终 Lysholm 评分<65 或低于术前评分（n=3）而失败。修复后整体 Kaplan-Meier 生存率在 5 年时为 99%，6 年时为 98%，7 年时为 95%，8 年时为 92%。
在 MMPRT 患者中，胫骨结节内移术治疗具有较高的临床生存率，且患者在中-长期随访检查中表现出临床改善。
IV 级，回顾性非对照病例系列研究。
