The aim of this study was to evaluate the clinical outcome of freeze-dried compared to fresh frozen allograft tissue used as a substitute for a ruptured ACL of the knee. In addition, the incidence of any graft rejection phenomena was recorded. Forty-one patients with ACL deficient knees underwent reconstructive surgery using a patellar bone-tendon-bone allograft that had been freeze-dried (Group 1, N = 14) or fresh frozen (Group 2, N = 27). All patients underwent the same implant technique and rehabilitation program. Followup ranged from 24 to 36 months. The evaluation consisted of subjective, objective, and instrumented laxity testing (KT-1000, MEDmetric, San Diego, CA; and Genucom, FARO Medical Technologies, Inc., Montreal, Canada). There were 31 males and 10 females. Eleven (79%) patients in Group 1 thought their knee was "normal" or "improved," and 25 (93%) in Group 2 thought the same. In addition, 10 (71%) patients in Group 1 denied any "giving way," compared to 26 (96%) in Group 2. The mean Lysholm knee score in Group 1 was 86/100 (range, 22 to 100) compared to 92/100 (range, 59 to 100). Clinical examination included the Lachman test and tests for anterior drawer sign and pivot shift. Postoperatively, Group 1 patients had the following results: Lachman test--seven Grade 0, six Grade 1, one Grade 2; anterior drawer sign--eight Grade 0, five Grade 1, one Grade 2; and pivot shift--seven Grade 0, five "trace," and two "present."(ABSTRACT TRUNCATED AT 250 WORDS)
本研究的目的是评估冻干同种异体组织与新鲜冷冻同种异体组织作为膝关节前交叉韧带断裂替代物的临床疗效。此外，记录任何移植物排斥现象的发生率。41例前交叉韧带缺失的膝关节患者接受了使用冻干髌腱骨移植物（第1组，N = 14）或新鲜冷冻髌腱骨移植物（第2组，N = 27）的重建手术。所有患者均采用相同的植入技术和康复方案。随访时间为24至36个月。评估包括主观、客观和仪器化的松弛度测试（KT - 1000，MEDmetric，加利福尼亚州圣地亚哥；以及Genucom，FARO医疗技术公司，加拿大蒙特利尔）。患者中有31名男性和10名女性。第1组中有11名（79%）患者认为其膝关节“正常”或“改善”，第2组中有25名（93%）患者有同样的看法。此外，第1组中有10名（71%）患者否认有任何“打软腿”现象，而第2组中有26名（96%）患者否认。第1组的Lysholm膝关节平均评分为86/100（范围为22至100），第2组为92/100（范围为59至100）。临床检查包括Lachman试验、前抽屉试验和轴移试验。术后，第1组患者的结果如下：Lachman试验——7例0级，6例1级，1例2级；前抽屉试验——8例0级，5例1级，1例2级；轴移试验——7例0级，5例“微量”，2例“存在”。（摘要截断于250字）
