A cohort of 39 patients (28 male, 11 female) that had undergone total meniscectomy as adolescents (mean age 16 years) underwent FISP 3D Magnetic Resonance Imaging at a mean follow up of 30 years. The presence of meniscal tissue was assessed by two independent observers blinded to the operation details. The volume of any meniscal tissue present was calculated. A posterior horn remnant was seen in 57% of medial and 45% of lateral meniscectomy cases. The mean volume of an operated medial meniscal remnant was 0.29 mL compared with a mean volume of 1.15 mL for an intact medial meniscus. The mean volume of an operated lateral meniscal remnant was 0.30 mL compared with 1.07 mL for an intact lateral meniscus. We have shown that the incidence of incomplete excision of the posterior horn is more common after total medial meniscectomy, and that at a mean follow up of 30 years there is no convincing in vivo MRI evidence of long-term meniscal regeneration.
一组39例患者（28例男性，11例女性）在青少年时期（平均年龄16岁）接受了全半月板切除术，平均随访30年时进行了快速成像稳态进动序列三维磁共振成像。由两名对手术细节不知情的独立观察者评估半月板组织的存在情况。计算存在的任何半月板组织的体积。在57%的内侧半月板切除术病例和45%的外侧半月板切除术病例中可见后角残余。手术内侧半月板残余的平均体积为0.29 mL，而完整内侧半月板的平均体积为1.15 mL。手术外侧半月板残余的平均体积为0.30 mL，而完整外侧半月板的平均体积为1.07 mL。我们已经表明，内侧半月板全切除术后后角切除不完全的发生率更为常见，并且在平均30年的随访中，没有令人信服的体内MRI证据表明半月板能长期再生。
