本研究的目的是确定Skyline X线片在诊断髌股骨关节炎中的有用性。此外，我们想评估髌股捻发音作为这种情况的临床体征的有用性。77名计划接受膝关节手术的患者接受了标准的前后位、侧位和天际线X线检查。术前还记录了临床髌骨-股骨捻发音的存在。在手术中，他们的髌股关节根据有无骨关节炎分为两组。将侧位和天际线位X线片以及髌股捻发音与手术结果进行单独比较。天际线视图的敏感性为79%，特异性为80%。侧位片的敏感性为82%，特异性为65%。髌股捻发音作为诊断膝关节炎的敏感性为89%，特异性为82%。在诊断髌股骨关节炎的敏感性和特异性方面，两种影像学视图之间没有统计学显著差异。因此，我们不能推荐skyline视图作为所有疑似髌股骨关节炎病例的常规放射学检查。
The aim of this study was to determine the usefulness of the skyline radiograph in the diagnosis of patellofemoral osteoarthritis. Additionally, we wanted to assess the usefulness of patello-femoral crepitus as a clinical sign of this condition. Seventy-seven patients scheduled to undergo knee surgery had standard antero-posterior, lateral and skyline X-rays of their affected knee. The presence of clinical patello-femoral crepitus was also documented preoperatively. At the operation, their patellofemoral joints were graded into two groups according to the presence or absence of osteoarthritis. The lateral and skyline view X-rays as well as patello-femoral crepitus were compared individually against the operative findings. The skyline view had a sensitivity of 79% and a specificity of 80%. The lateral view had a sensitivity of 82% and specificity of 65%. Patello-femoral crepitus as a sign had a sensitivity of 89% and a specificity of 82%. There was no statistically significant difference between the two radiological views in terms of sensitivity and specificity in the diagnosis of patellofemoral osteoarthritis. Hence, we cannot recommend the skyline view as a routine radiological investigation in all cases of suspected patellofemoral osteoarthritis.
