The aim of this study was to establish the aetiology and circumstances of meniscal injuries in the general adult population. We studied a group of patients who underwent arthroscopy under the care of the same surgeon between 1991 and 1998 (1236 patients). The study group included 392 patients, aged 18 to 60 years, with no previous knee injury, surgery or arthritis, with normal X-rays and meniscal injuries proven at arthroscopy. No professional athletes were included in the study group. The patients with Sports injuries (mean age 33 years) accounted for 32.4% of cases. The patients with Non-sporting injuries (mean age 41 years) accounted for 38.8% of tears. 71.9% of these happened in activities of daily living (and half of this group sustained their tear by squatting or ascent from this position). Patients without identifiable injury (mean age 43 years) represented 28.8% of cases. Male:Female ratio was 4:1. Medial tears accounted for two thirds of cases. This type of study, not undertaken since the advent of MRI or arthroscopy, shows that in the general population, two thirds of meniscal tears occurred in the absence of sporting activities, frequently within the ambit of every day activities and in the absence of the classic injury mechanism. Ascent from a squat is a common mechanism of injury not widely described or emphasised.
本研究的目的是确定普通成年人群半月板损伤的病因及情况。我们研究了一组在1991年至1998年间由同一位外科医生诊治并接受关节镜检查的患者(共1236例)。研究组包括392例年龄在18至60岁之间、既往无膝关节损伤、手术史或关节炎、X线检查正常且经关节镜检查证实有半月板损伤的患者。研究组未纳入职业运动员。运动损伤患者(平均年龄33岁)占病例的32.4%。非运动损伤患者(平均年龄41岁)占撕裂病例的38.8%。其中71.9%发生在日常生活活动中(且该组中有一半是在蹲姿或从蹲姿起身时发生撕裂)。无明确损伤患者(平均年龄43岁)占病例的28.8%。男女比例为4:1。内侧撕裂占病例的三分之二。自MRI或关节镜问世以来尚未进行过此类研究,结果表明,在普通人群中,三分之二的半月板撕裂发生在无体育活动的情况下,且经常发生在日常活动范围内,并无典型的损伤机制。从蹲姿起身是一种常见的损伤机制,但此前未被广泛描述或强调。
