前交叉韧带(ACL)的粘液样变性可以通过关节镜清理术治疗,然而,不稳定可能随之而来。这里,我们介绍了一名60多岁且有活动的ACL严重黏液样变性的女性,她接受了保守性关节镜下清创术和静脉内给予富血小板血浆(PRP)治疗.一个月后,患者的活动范围和疼痛症状显着改善,无结果松弛。患者能够恢复所有娱乐体育活动和专业职责。术后6个月进行的定量MRI显示纤维取向改善并形成了新的平行纤维。与术前扫描相比,平均灰度值显示较暗的像素强度,标准偏差(SD)较小,可能表明韧带组织的形成更均匀且变化较小。因此,PRP不会造成伤害,并且与关节镜下清创术联合使用会带来益处。
Mucoid degeneration of the anterior cruciate ligament (ACL) can be treated with arthroscopic debridement, however, instability can ensue. Here, we present a fit and active woman in her 60s with severe mucoid degeneration of the ACL who underwent conservative arthroscopic debridement and treatment with intraligamentous administration of platelet-rich plasma (PRP). After 1 month, the patient demonstrated significant improvements in range of motion and pain symptoms, with nil resultant laxity. The patient was able to return to all recreational sporting activities and professional duties. Quantitative MRI conducted 6 months postoperatively revealed improved fibre orientation and formation of new parallel fibres. Compared with the preoperative scan, the mean grey value demonstrated darker pixel intensity with a smaller standard deviation (SD), potentially indicating a more uniform and less variable formation of ligamentous tissue. Therefore, PRP did not cause harm and was associated with benefit in combination with arthroscopic debridement.
