Although knee injuries in professional soccer (football) have been extensively studied, the prevalence of knee osteoarthritis (OA) in veteran players is not well documented.
To investigate the prevalence of knee OA in retired professional soccer players in comparison with a group of athletically active military personnel.
Cross-sectional study; Level of evidence, 3.
A group of 100 veteran Greek soccer players aged 35 to 55 years (mean [±SD] age, 46.90 ± 5.9 years) were examined for knee OA and were administered the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire. A matched group of 100 athletically active military personnel served as a comparison group.
The sonographic prevalence of OA was significantly higher in the veteran soccer group (52%) than in the military group (33%) (n = 200; P = .010). This difference remained significant even after excluding participants with a history of knee surgery (44.1% vs 25.3%, respectively) (n = 151; P = .010). Femoral cartilage thickness was similar between the 2 groups (P = .473), while altered knee alignment had no effect on the prevalence of OA (P = .740). With the exception of perceived pain being more prevalent in the military group, there were no other statistically significant differences between the 2 groups in KOOS values.
Veteran soccer players had a higher sonographic prevalence of knee OA but better pain scores than a matched group of athletically active military personnel.
尽管职业足球运动中的膝部损伤已得到广泛研究，但资深球员膝骨关节炎（OA）的患病率尚无充分记录。
调查退役职业足球运动员膝OA的患病率，并与一组体育活动活跃的军事人员进行比较。
横断面研究；证据等级，3级。
对100名年龄在35至55岁（平均[±标准差]年龄，46.90±5.9岁）的希腊资深足球运动员进行膝OA检查，并对其进行膝伤与骨关节炎转归评分（KOOS）问卷调查。选取100名体育活动活跃的军事人员作为匹配组作为对照组。
资深足球运动员组OA的超声患病率（52%）显著高于军事人员组（33%）（n = 200；P = 0.010）。即使排除有膝部手术史的参与者后，这种差异仍然显著（分别为44.1%和25.3%）（n = 151；P = 0.010）。两组间股骨软骨厚度相似（P = 0.473），而膝关节对线改变对OA患病率无影响（P = 0.740）。除了军事人员组中感觉到的疼痛更为普遍外，两组在KOOS值方面没有其他统计学上的显著差异。
与一组体育活动活跃的军事人员匹配组相比，资深足球运动员膝OA的超声患病率更高，但疼痛评分更好。
