髌韧带肿瘤切除后四层聚丙烯补片重建伸膝装置一例报告

Reconstruction of the extensor mechanism with 4-layer polypropylene mesh after the excision of patellar tendon tumors:1 case report

髌韧带肿瘤是特殊部位的软组织肿瘤，治疗的过程髌韧带被切除，我们需要重建伸膝装置。我院收住髌韧带特殊部位肿瘤1例，在肿瘤切除后采用四层聚丙烯补片重建伸膝装置，结合其病史特点，通过回顾分析，针对其手术治疗措施进行相关探讨，总结相关治疗经验。

In this article, the therapeutic process and effects were retrospectively analyzed in a patient with malignant ifbrous histiocytomas in special parts of the patellar tendon. During the therapeutic process, the extensor mechanism was reconstructed with 4-layer polypropylene mesh after preoperative neoadjuvant chemotherapy and intraoperative wide excision of patellar tendon tumors. Adjuvant chemotherapy and radiotherapy were performed postoperatively in case of tumor recurrence. The patient was followed up continuously for 15 months after the surgery. No local tumor recurrence was found, and the lfexion and extension functions of the right knee joint were restored. Based on the clinical observation combined with previous clinical ifndings, it was thought that 4-layer polypropylene mesh could provide the mechanical strength and physiological compatibility needed for reconstruction of the extensor mechanism. Together with radiotherapy and chemotherapy, 4-layer polypropylene mesh could also be applied for reconstruction of the extensor mechanism in place of autologous tendon transplantation after the surgical treatment of low-grade malignant tumors, and the function of the knee joint could be maintained. Therefore, it was worth carrying out the further study.
