Several suture repair techniques have been reported for radial tear close to the posterior lateral meniscal root (type II PLMRT). However, no study has evaluated the clinical results after repair using the FasT-Fix system. This paper describes a novel H-plasty surgical repair technique and reports its clinical results.
From January 2015 to January 2017, 47 patients underwent repair of type II PLMRT with concomitant anterior cruciate ligament reconstruction and were included in this study. Assessments performed preoperatively and at final follow-up included the Lysholm score, subjective International Knee Documentation Committee (IKDC) score, and knee stability assessments (pivot-shift test, Lachman test, KNEELAX arthrometer side-to-side difference). Magnetic resonance imaging was used to compare the lateral meniscal extrusion pre- versus postoperatively. Second-look arthroscopy was performed to evaluate the meniscal healing in 38 cases.
Forty-seven patients were followed up for an average of 30.7 months (range 18-46 months). No patients experienced meniscal mechanical symptoms. At final follow-up, there were significant improvements in the Lysholm score, IKDC score, knee stability assessments, and lateral meniscal extrusion compared with the preoperative values. In the 38 of 47 patients that underwent second-look arthroscopy after an average of 17.5 months (range 14-19 months), all repairs (100%) were completely healed.
The novel H-plasty repair using the FasT-Fix system was an effective surgical treatment for type II PLMRT. Considering the satisfactory clinical results and the convenience of the surgery, H-plasty repair is recommended to be used preferentially.
已有多种缝合修复技术用于修复靠近后外侧半月板根部（II 型 PLMRT）的半月板后根部撕裂。然而，尚无研究评估使用 FasT-Fix 系统修复后的临床效果。本文介绍了一种新的 H 成形术手术修复技术，并报告了其临床结果。
2015 年 1 月至 2017 年 1 月，47 例患者接受了 II 型 PLMRT 修复术，同时进行了前交叉韧带重建，这些患者均纳入本研究。术前和末次随访时进行的评估包括 Lysholm 评分、主观国际膝关节文献委员会（IKDC）评分和膝关节稳定性评估（膝关节旋转轴试验、lachman 试验、KNEELAX 关节计侧间差值）。磁共振成像用于比较术前和术后外侧半月板外突情况。对 38 例患者进行了二次关节镜检查，以评估半月板愈合情况。
47 例患者平均随访 30.7 个月（18-46 个月）。无患者出现半月板机械性症状。末次随访时，与术前相比，Lysholm 评分、IKDC 评分、膝关节稳定性评估和外侧半月板外突均有显著改善。在平均随访 17.5 个月（14-19 个月）后接受二次关节镜检查的 38 例患者中，所有修复（100%）均完全愈合。
使用 FasT-Fix 系统的新型 H 成形术修复是 II 型 PLMRT 的有效手术治疗方法。考虑到满意的临床结果和手术的便利性，建议优先使用 H 成形术修复。
