Describe the evolution of the reconstruction of meniscal rim with semitendinosus tendon in a patient with knee pain after a subtotal meniscectomy and absence of meniscal wall.
32 years old male with a six-month history of the left knee pain after a subtotal meniscectomy. The MRI indicated a small internal meniscal remainder without posterior horn attachment. Taking this absence as a relative contraindication for implant and meniscal transplantation, the reconstruction of a new meniscal wall with semitendinosus tendon autograft was considered. A collagen meniscal implant was attached to the new wall five months later.
After two years the patient referred only non specific discomfort with full pain relief in the medial compartment. The MRI revealed integration of implants without significant degenerative changes compared to previous images.
This staged technique was designed to restore medial meniscus-like biologic tissue in a symptomatic patient following arthroscopic subtotal meniscectomy with a significant loss of the peripheral meniscus rim. Symptomatic improvement was obtained at two years follow-up.
描述在半月板次全切除术后半月板壁缺失且膝关节疼痛的患者中，使用半腱肌腱重建半月板边缘的演变过程。
一名32岁男性，半月板次全切除术后左膝疼痛6个月。MRI显示内侧半月板有一小部分残留，后角无附着。鉴于此缺失情况被视为植入物和半月板移植的相对禁忌证，考虑使用半腱肌腱自体移植重建新的半月板壁。五个月后，将胶原半月板植入物附着于新壁上。
两年后，患者仅诉说有非特异性不适，内侧间室疼痛完全缓解。MRI显示植入物已整合，与之前的图像相比无明显退变改变。
这种分期技术旨在为关节镜下半月板次全切除术后出现症状且外周半月板边缘严重缺失的患者恢复类似内侧半月板的生物组织。随访两年获得了症状改善。
