Abstract

Objective: The aim of the present study was to determine physiological reference values for the morphology of the patella and to analyse these parameters according to patella position in healthy knee joints.

Material and methods: Healthy knee joints of 409 patients (mean age, 52.3 years [± 16.8]) were analysed retrospectively on MRI images for Insall-Salvati index (ISI), sagittal patella thickness (PTS) and patella length (PLS) as well as axial patella thickness (PTA) and patella width (PWA). Differences between patellar diameters were analysed depending on ISI, side, age and gender.

Results: Mean PTS was 20.1 mm (± 2.4), PLS 44.0 mm (± 4.4), PTA 21.8 mm (± 2.4) and PWA 44.5 mm (± 4.7). Depending on the vertical patellar position (ISI), all patellar parameters (p < 0.01) showed significant differences between patients with a patella alta, norma and baja. In general, a smaller ISI showed higher measured values for the patellar parameters. There were no significant differences for the laterality. Only PTS showed a significant age difference (p = 0.031). All parameters were significantly larger in male compared to female knees (p < 0.001).

Conclusion: Reference parameters for the patella morphology are reported. Concluding from the results, a relationship between vertical patellar position and patellar morphology seems to exist. This finding should be taken into account in diagnostics and therapy of patella disorders.

成人膝关节髌股关节生理形态的核磁共振成像分析。

研究目的本研究旨在确定髌骨形态的生理参考值，并根据健康膝关节中髌骨的位置对这些参数进行分析。材料和方法：对 409 名患者（平均年龄 52.3 岁 [±16.8]）的健康膝关节进行 MRI 图像回顾性分析，包括 Insall-Salvati 指数 (ISI)、矢状面髌骨厚度 (PTS) 和髌骨长度 (PLS)，以及轴向髌骨厚度 (PTA) 和髌骨宽度 (PWA)。根据 ISI、侧位、年龄和性别分析了髌骨直径之间的差异：平均PTS为20.1毫米（±2.4），PLS为44.0毫米（±4.4），PTA为21.8毫米（±2.4），PWA为44.5毫米（±4.7）。根据髌骨垂直位置（ISI），所有髌骨参数（p 结论：髌骨形态学参考参数的变化与髌骨垂直位置（ISI）有关：报告了髌骨形态的参考参数。根据结果得出结论，髌骨垂直位置与髌骨形态之间似乎存在关系。在诊断和治疗髌骨疾病时应考虑到这一发现。

期刊介绍： Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration. This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
