Transtibial pullout repair of medial meniscus posterior root tears (MMPRTs) cannot prevent the progression of knee osteoarthritis. Conversions of knee arthroplasties are occasionally required following MMPRT repair. However, other knee-related surgical treatments following MMPRT repair are unclear. This study was aimed at investigating the midterm clinical outcomes and knee-related surgical events following MMPRT repair.
Patients with MMPRT underwent pullout repair using FasT-Fix modified Mason-Allen (F-MMA) suturing with an all-inside meniscal repair device. Thirty-two patients with follow-up duration >2 years were enrolled. We assessed the clinical outcomes and postoperative surgical treatment of both knees.
F-MMA pullout repair improved all clinical evaluation scores in patients with MMPRT at a mean follow-up of 36.1 months. Postoperative arthroscopic debridement was required for one patient. An additional MMPRT repair was performed in one patient on second-look arthroscopy. None of the patients required ipsilateral knee arthroplasty. In the contralateral knees, one pullout repair of a newly developed MMPRT and two knee arthroplasties were performed.
This study demonstrated that F-MMA pullout repair yielded satisfactory clinical outcomes. However, subsequent knee-related surgeries were observed in 6.3% of the pullout-repaired knees and 9.4% of the contralateral knees. Our results suggest that surgeons should be aware of the worsening and/or occurrence of contralateral knee joint disease, even when the postoperative clinical outcomes are satisfactory following MMPRT repair.

经胫骨隧道抽出修复内侧半月板后根撕裂（MMPRT）无法预防膝关节骨关节炎的进展。MMPRT 修复后偶尔需要进行膝关节置换术转换。然而，MMPRT 修复后其他与膝关节相关的手术治疗尚不清楚。本研究旨在调查 MMPRT 修复后中期临床结果和与膝关节相关的手术事件。
采用 FasT-Fix 改良 Mason-Allen（F-MMA）缝线和全内半月板修复装置对 MMPRT 患者进行抽出修复。纳入 32 例随访时间>2 年的患者。我们评估了双膝的临床结果和术后手术治疗。
F-MMA 抽出修复在 MMPRT 患者平均随访 36.1 个月时改善了所有临床评估评分。1 例患者需要术后关节镜下清创术。1 例患者在二次关节镜检查时行额外的 MMPRT 修复。无一例患者需要同侧膝关节置换术。在对侧膝关节中，1 例新发生的 MMPRT 抽出修复和 2 例膝关节置换术。
本研究表明，F-MMA 抽出修复可获得满意的临床结果。然而，在 6.3%的抽出修复膝关节和 9.4%的对侧膝关节中观察到随后的与膝关节相关的手术。我们的结果表明，即使 MMPRT 修复后的术后临床结果令人满意，外科医生也应该意识到对侧膝关节疾病的恶化和/或发生。
