The standard treatment of the posterior cruciate ligament (PCL) rupture accompanied with the posterior root of medial meniscus (PRMM) tears is controversial. Our research describes a minimally invasive technique for the PCL rupture accompanied with the PRMM tears.
We described a "U" shape suture and shared tunneling technique to treat the PCL rupture accompanied with PRMM tears. Three patients (ages 28, 42, and 59 years old) who underwent this surgery have been followed up for more than 1 year at most. The MRI was done, and the hospital for special surgery (HSS) score was adopted to evaluate the clinical effect. Firstly, we built both femoral and tibial bone tunnels for the PCL reconstruction. Secondly, we used the suture hook to pass the suture line through the PRMM. Thirdly, we passed the prepared tendon through the bone tunnel and fixed the prepared tendon by an endobutton plate and an interference screw (Smith & Nephew) respectively on the side of the femur and tibia. At last, we used an endobutton plate (Smith & Nephew) outside the tibial bone tunnel to fix the PRMM.
These three patients did not show any complications. At 1 year after the operation, we found good knee stability, negative posterior drawer test, and normal range of motion compared with the contralateral knee joint. The MRI also showed a good union of the PRMM and PCL. The hospital for special surgery (HSS) score was 90 points.
With an ideal therapeutic effect, this technique is worthy to be promoted for patients with the PCL rupture and PRMM tears.
后交叉韧带（PCL）断裂伴内侧半月板后根（PRMM）撕裂的标准治疗方法存在争议。我们的研究描述了一种针对PCL断裂伴PRMM撕裂的微创技术。
我们描述了一种“U”形缝合和共用隧道技术来治疗PCL断裂伴PRMM撕裂。三名接受该手术的患者（年龄分别为28岁、42岁和59岁），最长随访时间超过1年。进行了MRI检查，并采用特殊外科医院（HSS）评分来评估临床效果。首先，我们为PCL重建构建股骨和胫骨骨隧道。其次，我们使用缝合钩将缝线穿过PRMM。第三，我们将准备好的肌腱穿过骨隧道，并分别在股骨和胫骨侧用纽扣钢板和干涉螺钉（史赛克）固定准备好的肌腱。最后，我们在胫骨骨隧道外使用纽扣钢板（史赛克）固定PRMM。
这三名患者均未出现任何并发症。术后1年，我们发现膝关节稳定性良好，后抽屉试验阴性，与对侧膝关节相比活动范围正常。MRI还显示PRMM和PCL愈合良好。特殊外科医院（HSS）评分为90分。
该技术治疗效果理想，值得推广应用于PCL断裂伴PRMM撕裂的患者。
