Abstract

Purpose: The meniscal vascularization remains poorly documented, particularly its origin. The aim of this cadaveric study was to describe the origin of the arterial vascularization of the menisci.

Methods: This is an anatomical study on human specimens. Twenty knees were used. The average age of the subjects was 82.7 years old (56-97). Ten knees were injected with latex-neoprene and ten knees were injected with colored gelatin mixed with India ink. The same protocol for dissection was used in all cases.

Results: The meniscal vascularization is provided by the genicular arteries of the knee originating from the popliteal artery. The superior medial, superior lateral, inferior medial, inferior lateral, and middle genicular arteries had constant pathways. A second middle genicular artery was found in 55% of cases. The inferior lateral genicular artery ran alongside the meniscal's periphery. The inferior medial genicular artery followed the proximal tibial metaphysis. In all dissections, a previously undocumented small artery originated from under the middle genicular arteries. This artery remained extracapsular and followed the medial meniscal periphery. This artery has been named the "medial capsulo-meniscal artery". The genicular arteries formed an extensive peri-articular anastomotic vascularization for the menisci and thus referred to the "peri-meniscal arterial archs". The lateral peri-meniscal arch was predominantly supplied by the inferior lateral genicular artery, while the medial peri-meniscal arch was mainly supplied by the medial capsulo-meniscal artery.

Conclusion: The peri-meniscal arterial archs are a vascular complex formed by the genicular arteries of the knee and an artery not previously described: the "capsulo-meniscal artery". These archs have a constant presence but their formation and distribution is different between the medial and lateral menisci.

半月板血管化:半月板弓周围的描述性研究。
目的:有关半月板血管化,尤其是其起源的文献仍然很少。这项尸体研究旨在描述半月板动脉血管的起源:这是一项对人体标本的解剖学研究。共使用了 20 个膝盖。受试者的平均年龄为 82.7 岁(56-97 岁)。十个膝盖注射了乳胶-新戊二烯,十个膝盖注射了与印度墨水混合的彩色明胶。所有病例均采用相同的解剖方案:结果:半月板血管由源自腘动脉的膝关节膝动脉提供。膝关节上内侧动脉、上外侧动脉、下内侧动脉、下外侧动脉和膝关节中动脉的路径恒定不变。55%的病例发现有第二条膝关节中动脉。下外侧膝状动脉沿着半月板外周运行。下内侧膝状动脉沿着胫骨近端干骺端运行。在所有的解剖中,有一条以前未被记录的小动脉源自膝关节中动脉下方。这条动脉仍在囊外,沿着内侧半月板外周。这条动脉被命名为 "内侧囊-半月板动脉"。膝状动脉为半月板形成了广泛的关节周围血管吻合,因此被称为 "半月板周围动脉弓"。外侧半月板周围动脉弓主要由下外侧膝状动脉供应,而内侧半月板周围动脉弓主要由内侧囊-半月板动脉供应:结论:半月板周围动脉弓是由膝关节的膝关节动脉和一种以前未曾描述过的动脉--"半月板囊动脉 "形成的血管复合体。这些动脉弓一直存在,但其形成和分布在半月板内侧和外侧有所不同。

期刊介绍: Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
