The aim of this study is to determine the prevalence of pathologic findings in asymptomatic knees of Kangoo Jumpers by using a 3T MRI and to compare them with age and sex-matched controls who do not regularly participate in any impact sports.
Both knees of 18 Kangoo Jumpers were examined by 3T MRIs in a total of 36 MRI scans. The control group was comprised of 20 volunteers from the same age group and with similar weights who did not participate in any competitive sports, in a total of 40 MRI scans. Two orthopedists and one radiologist independently assessed all images for the presence or absence of any abnormalities.
In 32 (88.9%) of the 36 Kangoo Jumpers' knees, one or more abnormalities were observed. The most prevalent abnormality was bone marrow edema, which was detected in 32 knees (88.9%). The other significant findings were quadriceps tendinopathy (80.6%), patellar tendinopathy (63.9%), gastrocnemius tendinopathy (63.9%), infrapatellar fat pad edema (75%), suprapatellar fat pad edema (63.9%), meniscal signal change (72.2%) and cartilage damage in the patellofemoral joint (72.2%). There were no statistically significant differences in terms of joint effusion (8.3%), ganglion cysts (8.3%) or tibiofemoral joint cartilage injury (0%).
This study reveals many types of knee MRI findings of asymptomatic Kangoo Jumpers compared to the control group. These MRI findings may be associated with acute knee injuries or chronic joint problems such as osteoarthritis, which may develop in long-term follow-up studies.
本研究旨在使用 3T MRI 确定无症 状 Kangoo Jumpers 膝关节的病理表现，并将其与年龄和性别匹配、不经常参加任何冲击运动的对照组进行比较。
对 18 名 Kangoo Jumpers 的双膝共进行了 36 次 MRI 检查。对照组由来自同一年龄组且体重相似的 20 名志愿者组成，他们不参加任何竞技运动，共进行了 40 次 MRI 检查。两名骨科医生和一名放射科医生独立评估所有图像是否存在任何异常。
在 36 名 Kangoo Jumpers 的 32 个（88.9%）膝关节中，观察到一个或多个异常。最常见的异常是骨髓水肿，在 32 个膝关节（88.9%）中检测到。其他重要发现包括股四头肌肌腱病（80.6%）、髌腱病（63.9%）、腓肠肌腱病（63.9%）、髌下脂肪垫水肿（75%）、髌上脂肪垫水肿（63.9%）、半月板信号改变（72.2%）和髌股关节软骨损伤（72.2%）。关节积液（8.3%）、神经节囊肿（8.3%）或胫股关节软骨损伤（0%）在统计学上无显著差异。
与对照组相比，本研究揭示了无症状 Kangoo Jumpers 膝关节的多种 MRI 表现。这些 MRI 表现可能与急性膝关节损伤或慢性关节问题如骨关节炎有关，这些问题可能会在长期随访研究中发展。
