The purpose of this study was to evaluate the functional and radiographic results on a midterm basis, as well as complications, in an initial series of meniscal allograft transplantations performed with suture fixation without any bone block.
A series of 33 meniscal allograft transplantations were performed at our institution from January 2001 to October 2003. Inclusion criteria were patients with compartmental joint line pain due to a previous meniscectomy. There were 24 men and 9 women with a mean age of 38.8 years (range, 21 to 54 years). The functional outcomes were evaluated by use of Lysholm and Tegner scores at a mean and minimum follow-up of 6.5 years and 5 years, respectively. A visual analog scale for pain was also used. Radiographic assessment included joint space narrowing on the Rosenberg view and magnetic resonance imaging evaluation.
The Lysholm and Tegner scores significantly improved from 65.4 to 88.6 (P < .001) and from 3.1 to 5.5 (P < .001), respectively, after surgery. The visual analog scale score significantly dropped from 6.4 to 1.5 (P < .001). The radiographic evaluation did not show any joint space narrowing (P = .38). Meniscal extrusion was a constant finding, averaging 36.3% of total meniscal size. According to the Van Arkel criteria, the survival rate was 87.8% at 6.5 years. The rate of complications was 33%.
This study suggests that this procedure provides significant pain relief and functional improvement in selected symptomatic individuals on a midterm basis. However, there was a high rate of complications (33%) and revision surgery.
Level IV, therapeutic case series.
本研究旨在评估中期内（即最初系列半月板同种异体移植手术后的 6.5 年和 5 年随访期内）半月板同种异体移植术后的功能和影像学结果，以及并发症。
我们机构于 2001 年 1 月至 2003 年 10 月期间进行了一系列 33 例半月板同种异体移植手术。纳入标准为因先前半月板切除术而出现关节线间疼痛的患者。24 名男性和 9 名女性，平均年龄 38.8 岁（范围 21 至 54 岁）。功能结果通过 Lysholm 和 Tegner 评分进行评估，平均随访时间为 6.5 年，最小随访时间为 5 年。还使用视觉模拟评分法（VAS）评估疼痛。影像学评估包括 Rosenberg 位关节间隙变窄和磁共振成像（MRI）评估。
手术后，Lysholm 和 Tegner 评分分别从 65.4 分显著提高至 88.6 分（P<0.001）和从 3.1 分显著提高至 5.5 分（P<0.001），VAS 评分从 6.4 分显著下降至 1.5 分（P<0.001）。影像学评估未显示任何关节间隙变窄（P=0.38）。半月板挤出是一种恒定的发现，平均占半月板总大小的 36.3%。根据 Van Arkel 标准，6.5 年时的存活率为 87.8%。并发症发生率为 33%。
本研究表明，该手术在中期内为选定的有症状患者提供了显著的疼痛缓解和功能改善。然而，并发症（33%）和翻修手术的发生率较高。
