Partial meniscectomy, which is generally used for the treatment of meniscal tears, can lead to knee joint osteoarthritis. To prevent this important complication, attempting to restore normal knee joint kinematics and biomechanical forces after partial meniscectomy is essential. Implantation of a meniscal scaffold can be useful in this regard, improving the function of the meniscus on knee joint biomechanics after partial meniscectomy. Use of meniscal scaffolds would have specific clinical merit for young patients who are at highest for developing knee joint osteoarthritis over time. Herein, we describe our novel bioabsorbable meniscal scaffold, fabricated with polyglycolic acid coated with polylactic acid/caprolactone, used after partial meniscectomy for degenerative and irreparable meniscal tears. The method of implantation of the scaffold will have a determinant effect on clinical outcomes. As the implementation technique by arthroscopy will be influenced by the stiffness and strength of the scaffold implant used, we provide a detailed description of our implantation technique, including a description of the pitfalls to consider in order to improve clinical outcomes.
部分半月板切除术通常用于治疗半月板撕裂，但可能导致膝关节骨关节炎。为预防这一重要并发症，在部分半月板切除术后试图恢复正常的膝关节运动学和生物力学力量至关重要。在这方面，植入半月板支架可能有用，可改善部分半月板切除术后半月板对膝关节生物力学的功能。对于随着时间推移最易发生膝关节骨关节炎的年轻患者，使用半月板支架具有特定的临床价值。在此，我们描述了我们新型的可生物吸收半月板支架，它由涂有聚乳酸/己内酯的聚乙醇酸制成，用于部分半月板切除术后治疗退行性和不可修复的半月板撕裂。支架的植入方法将对临床结果产生决定性影响。由于关节镜实施技术会受到所用支架植入物的刚度和强度影响，我们详细描述了我们的植入技术，包括为改善临床结果而需考虑的陷阱。
