In-office needle arthroscopy has been reported as a diagnostic tool for different knee pathologies. In addition, ACL repair has seen a resurgence with the advent of innovative orthopedic devices. The aim of this study was to assess clinical, radiological, and in-office needle arthroscopic findings in 15 adult patients who underwent acute (within 14 days from injury) anterior cruciate ligament (ACL) repair. Fifteen patients voluntarily participated in the study. A second-look arthroscopy was performed with an in-office needle arthroscopy at an average of 7.2 months after the primary repair. The parameters included in the investigation were the continuity of the anatomical footprint of the repaired ACL, subjective assessment of the ACL tension with the probe, and synovial coverage of the ACL. All patients had a Magnetic Resonance Imaging (MRI) at 6 months after repair and an arthrometric evaluation with the KT-1000. Clinical evaluation with the scores, Tegner Lysholm Knee Scoring Scale (TLKSS), the Knee Injury and Osteoarthritis Outcome Score (KOOS), and International Knee Documentation Committee (IKDC) was performed at the final follow-up of 2 years. Moreover, a correlation between the characteristics of ACL appearance at the time of the second look in-office needle arthroscopy, MRI and KT-1000 was performed. The mean TLKSS was 97.86, the mean KOOS was 98.08 and the mean subjective IKDC was 96.71. The objective IKDC was A in 10 patients and B in 5 patients. ACL healing was graded as A in 11 patients and B in 4 patients. Synovial coverage was graded as good in 10 patients and fair in 5 while MRI assessment showed a type I ACL in 10 patients, type II in 4 patients and type III in 1 patient. In-office needle arthroscopy is a reliable tool to assess the condition of a repaired ACL. In addition, ACL repair performed in acute proximal tears demonstrated excellent clinical results.

初级 ACL 修复后的办公室内针关节镜评估：15 名患者的短期结果

据报道，办公室内针状关节镜检查可作为不同膝关节病变的诊断工具。此外，随着创新型骨科器械的出现，ACL 修复术再次兴起。本研究的目的是评估 15 名接受急性（受伤后 14 天内）前交叉韧带 (ACL) 修复的成年患者的临床、放射学和诊室针关节镜检查结果。十五名患者自愿参加了这项研究。在初次修复后平均 7.2 个月进行了二次关节镜检查，并在办公室内进行了针关节镜检查。调查中包括的参数是修复的 ACL 解剖足迹的连续性、探头对 ACL 张力的主观评估以及 ACL 的滑膜覆盖。所有患者在修复后 6 个月进行磁共振成像 (MRI) 并使用 KT-1000 进行关节测量评估。在 2 年的最终随访中进行了评分、Tegner Lysholm 膝关节评分量表 (TLKSS)、膝关节损伤和骨关节炎结局评分 (KOOS) 和国际膝关节文献委员会 (IKDC) 的临床评估。此外，进行了第二次诊室针关节镜检查时 ACL 外观特征、MRI 和 KT-1000 之间的相关性。平均 TLKSS 为 97.86，平均 KOOS 为 98.08，平均主观 IKDC 为 96.71。客观 IKDC 为 10 例患者为 A，5 例患者为 B。ACL愈合评分为A级11例，B级4例。10 例滑膜覆盖被评为良好，5 例为一般，而 MRI 评估显示 10 例患者为 I 型 ACL，4 例患者为 II 型，1 例患者为 III 型。办公室内针状关节镜检查是评估修复 ACL 状况的可靠工具。此外，在急性近端撕裂中进行的 ACL 修复显示出出色的临床效果。
