Prevention of the knee osteoarthritis following meniscectomy is implantation of an allotransplant or an artificial meniscus. We present retrospective study of our early results of the treatment using polyurethane meniscal scaffold.
From 2016 to 2020, we implanted nine polyurethane scaffolds (Actifit) after partial meniscectomy, five males and four females, age 36 (16-47), BMI 26.7 (17.2-35.9) kg/m. Functional status, activity, pain, and MRI were assessed.
FU 20.8 (6-48.5) months, 35.2 (0-68) months from the meniscectomy to the implantation. The average implant length was 46.1 (35-60) mm, average number of sutures was 7.6 (5-10). Lysholm score before surgery was 61.7 (49-85), after the surgery 86.4 (62-95) with p 0.0045, Tegner activity score before meniscectomy was 5.8 (4-7), after 3.8 (2-5), and after the scaffold implantation 4.6 (3-7) with p 0.0488. Before surgery, VAS score was 3.1 (2-4), and after 7.7 (5-9) with p 0.0042. Pursuant to the Genovese classification, the last follow-up MRI showed a type 2 meniscal morphology in four cases and a type 3 in five cases. Seven patients had type 1 and two had type 2 signal intensity. On average, the absolute extrusion of a transplanted meniscus was 3.67 mm, and the relative extrusion was 0.58 mm. Extrusion progress was not detected.
Significantly improved knee functionality, increased level of physical activity, and reduced pain. MRI analysis revealed the meniscal transplant morphology and volume loss, as well as its extrusion without progression.
预防半月板切除术后的膝关节骨关节炎的方法是植入同种异体移植物或人工半月板。我们介绍了使用聚氨酯半月板支架治疗的早期结果的回顾性研究。
在 2016 年至 2020 年期间，我们对 9 名半月板切除术后接受聚氨酯支架（Actifit）植入的患者进行了研究，其中 5 名男性，4 名女性，年龄 36（16-47）岁，BMI 为 26.7（17.2-35.9）kg/m2。评估了功能状态、活动能力、疼痛和 MRI。
随访时间为 20.8（6-48.5）个月，半月板切除术后至植入物植入的时间为 35.2（0-68）个月。平均植入物长度为 46.1（35-60）mm，平均缝线数为 7.6（5-10）根。术前 Lysholm 评分为 61.7（49-85），术后为 86.4（62-95），p<0.0045；术前 Tegner 活动评分为 5.8（4-7），术后为 3.8（2-5），术后支架植入后为 4.6（3-7），p=0.0488。术前 VAS 评分为 3.1（2-4），术后为 7.7（5-9），p=0.0042。根据 Genovese 分类，末次随访 MRI 显示 4 例为 2 型半月板形态，5 例为 3 型。7 例患者为 1 型，2 例为 2 型信号强度。平均而言，移植半月板的绝对挤出量为 3.67mm，相对挤出量为 0.58mm。未检测到挤出进展。
膝关节功能显著改善，活动水平提高，疼痛减轻。MRI 分析显示半月板移植的形态和体积丢失，以及无进展的挤出。
