To evaluate the relationship between limb function and radiographic evidence of stifle osteoarthrosis (OA) in dogs.
The relationship between force platform data and radiographic OA score was evaluated on 2 separate days using regression analysis. Interday variation was also assessed.
Forty-one dogs with visible lameness and radiographic evidence of stifle OA.
Force platform data were collected at a velocity of 1.7 to 2.0 m/s for 5 trials on day 1 and day 8. Radiographs taken on day 1 were scored using a previously reported OA scoring system.
No significant relationship was found between force platform data and OA score. No significant differences were found between any day 1 and day 8 force platform values.
Although radiographic evidence of stifle OA provides evidence of pathology, it does a poor job of representing limb function. In addition, the absence of significant differences between day 1 and day 8 values in this population of dogs supports use of only a single force platform evaluation before measuring a treatment effect.
The presence of OA in the stifle joint does not correlate with clinical function; radiographic outcome should be used cautiously as a predictor of clinical outcome.
评估犬后肢功能与后肢骨关节炎（OA）影像学证据之间的关系。
使用回归分析在两个不同日期评估力平台数据与影像学OA评分之间的关系。还评估了日间差异。
41只患有明显跛行且有后肢OA影像学证据的犬。
在第1天和第8天以1.7至2.0 m/s的速度收集力平台数据，共进行5次试验。使用先前报道的OA评分系统对第1天拍摄的X线片进行评分。
未发现力平台数据与OA评分之间存在显著关系。第1天和第8天的力平台值之间未发现显著差异。
虽然后肢OA的影像学证据提供了病理学证据，但它在反映肢体功能方面表现不佳。此外，在这群犬中第1天和第8天的值之间没有显著差异，这支持在测量治疗效果之前仅使用单次力平台评估。
后肢关节OA的存在与临床功能不相关；影像学结果作为临床结果的预测指标应谨慎使用。
