The purpose of this study is to investigate the clinical outcome for patients after knee ligament reconstructions with allografts at a university hospital.
A total of 33 patients received allografts for reconstructive knee surgery between 2007 and 2017. The follow up evaluation consisted of a clinical knee examination including evaluation of range of motion (ROM), lateral and medial laxity, the Lachman test, the Pivot shift test, the sag test, the posterior drawer test and checking for patellofemoral pain. The following patient-reported outcome measures (PROMs) were used; the Lysholm Function Score, the Tegner activity score, and the Knee injury and Osteoarthritis Outcome Score (KOOS).
Twenty-one (64%) patients were available for the follow-up evaluation and the mean follow-up time was 4.8 years. A total of 16 out of 21 patients had multiligament injuries of which the ACL was the ligament most frequently ruptured. At the time of follow-up, 14 out of 16 patients (87%) with ACL injury had Lachman test grade 0 or grade 1 + , and 12 out of 13 (92%) had a pivot shift grade 0 or 1 + . The mean Lysholm Score was 74. All mean KOOS subscale values were ≥ 59 at the follow-up. The preoperative Tegner activity score was 3 (range, 1-6) and 4 (range, 2-6) at follow up. There were no deep postoperative infections. A total of 19 out of 21 patients (90%) reported that they would have undergone surgery again had they known the clinical outcome in advance.
The patients improved from the preoperative score to the follow-up score in the knee-related Quality of Life (QoL) KOOS subscale. None of the patients were diagnosed with deep postoperative infections.
本研究旨在调查某大学医院同种异体移植物膝关节韧带重建术后患者的临床结局。
2007年至2017年间，共有33例患者接受了同种异体移植物进行膝关节重建手术。随访评估包括临床膝关节检查，其中包括评估活动范围（ROM）、内外侧松弛度、拉赫曼试验、轴移试验、凹陷试验、后抽屉试验以及检查髌股关节疼痛情况。使用了以下患者报告结局指标（PROMs）：Lysholm功能评分、Tegner活动评分以及膝关节损伤和骨关节炎结局评分（KOOS）。
21例（64%）患者可进行随访评估，平均随访时间为4.8年。21例患者中有16例（76%）存在多韧带损伤，其中前交叉韧带（ACL）是最常断裂的韧带。随访时，16例ACL损伤患者中有14例（87%）拉赫曼试验为0级或1+级，13例中有12例（92%）轴移试验为0级或1+级。Lysholm评分的平均值为74分。随访时KOOS各子量表的所有平均值均≥59分。术前Tegner活动评分为3分（范围为1 - 6分），随访时为4分（范围为2 - 6分）。术后无深部感染。21例患者中有19例（90%）表示，如果他们提前知道临床结局，仍会再次接受手术。
患者在与膝关节相关的生活质量（QoL）KOOS子量表中，从术前评分提高到了随访评分。所有患者均未被诊断为术后深部感染。
