T. Visuri et al., HEMARTHROSIS OF THE CLINICALLY STABLE KNEE DUE TO SPORTS AND MILITARYTRAINING IN YOUNG RECRUITS - AN ARTHROSCOPIC ANALYSIS, Military medicine, 158(6), 1993, pp. 378-381
Findings of an early arthroscopy performed in 108 consecutive hemarthr
otic and clinically stable knees were analyzed. The patients were youn
g conscripts, the mean age being 19.9 years. Fifty-seven of the knees
were injured during military training, 36 in different sports activiti
es, 9 at falls, and 6 in motorbike accidents. The lesions were divided
into ''primary'' (lesions needing operative treatment or the supposed
most common lesions in incidence) and ''secondary'' (other lesions).
An average of 1.6 lesions were observed per knee. Dislocation of the p
atella was the most common diagnosis in 38 (35%) cases. Dislocation of
the patella was associated with military exercise (p < 0.001). Lesion
s of the anterior cruciate ligament (ACL) were observed in 37 (34%) ca
ses. ACL ruptures were related to sport activities (p < 0.0001).
