Abstract

Background: The etiology and pathology of mucoid degeneration of the anterior cruciate ligament (MD-ACL) remain poorly understood. MD-ACL may be associated with knee osteoarthritis (OA) or a mechanism other than OA. This study evaluated the radiological differences between knees with MD-ACL and those with a normal ACL and compared the clinical and radiological features of knees with MD-ACL according to the knee OA status.

Methods: This retrospective study compared the radiological features of the intercondylar notch width index (NWI) and posterior tibial slope (PTS) of 67 MD-ACL patients (MD group) and 67 age-, sex-, and OA grade-matched patients with a normal ACL (control group). During the subgroup analysis, MD-ACL patients were divided into the non-OA subgroup (n = 41) and OA subgroup (n = 26). The pain location and characteristics of the knee, PTS, and NWI were compared between these subgroups.

Results: Compared to the control group, the MD group had a lower NWI (0.26 ± 0.03 vs. 0.28 ± 0.01, p < 0.001) and a larger PTS (11.3° ± 3.0° vs. 9.2° ± 2.5°, p < 0.001). During the subgroup analysis, the most common pain locations were the posterior and medial aspects of the knee in the non-OA subgroup (43.9%) and OA subgroup (53.8%), respectively. Pain on terminal flexion was the most common pain characteristic in both subgroups (non-OA subgroup, 73.1%; OA subgroup, 53.8%). The PTS was not different between subgroups (11.7° ± 3.2° in the non-OA subgroup vs. 10.6° ± 2.7° in the OA subgroup; p = 0.159). However, the non-OA subgroup had a lower NWI than the OA subgroup (0.25 ± 0.03 vs. 0.28 ± 0.02, p = 0.001).

Conclusions: Patients with MD-ACL had a lower NWI and a larger PTS than patients with a normal ACL. Furthermore, the clinical and radiological features of MD-ACL differed according to the knee OA status. A narrow intercondylar notch may be more closely associated with the development of MD-ACL without OA.

膝关节骨关节炎状态不同，膝关节前十字韧带黏液变性的临床和放射学特征也不同吗？

背景：前十字韧带粘液变性（MD-ACL）的病因和病理仍不甚明了。MD-ACL 可能与膝关节骨性关节炎（OA）有关，也可能与 OA 以外的其他机制有关。本研究评估了患有 MD-ACL 的膝关节与前交叉韧带正常的膝关节之间的放射学差异，并根据膝关节 OA 状态比较了患有 MD-ACL 的膝关节的临床和放射学特征：这项回顾性研究比较了 67 名 MD-ACL 患者（MD 组）和 67 名年龄、性别和 OA 等级匹配的前交叉韧带正常患者（对照组）的髁间切迹宽度指数（NWI）和胫骨后斜坡（PTS）的放射学特征。在亚组分析中，MD-ACL 患者被分为非 OA 亚组（41 人）和 OA 亚组（26 人）。结果显示，与对照组相比，MD-ACL患者的膝关节疼痛部位和特征、PTS和NWI均低于对照组：与对照组相比，MD 组的 NWI 更低（0.26 ± 0.03 vs. 0.28 ± 0.01，P < 0.001），PTS 更大（11.3° ± 3.0° vs. 9.2° ± 2.5°，P < 0.001）。在亚组分析中，非 OA 亚组（43.9%）和 OA 亚组（53.8%）最常见的疼痛部位分别是膝关节后侧和内侧。末端屈曲时的疼痛是两个亚组最常见的疼痛特征（非 OA 亚组，73.1%；OA 亚组，53.8%）。亚组之间的 PTS 没有差异（非 OA 亚组为 11.7° ± 3.2° vs. OA 亚组为 10.6° ± 2.7°；P = 0.159）。然而，非 OA 亚组的 NWI 低于 OA 亚组（0.25 ± 0.03 vs. 0.28 ± 0.02，p = 0.001）：结论：与前交叉韧带正常的患者相比，MD-ACL 患者的 NWI 更低，PTS 更大。此外，膝关节 OA 状态不同，MD-ACL 的临床和放射学特征也不同。髁间切迹狭窄可能与无 OA 的 MD-ACL 的发生更密切相关。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
