We performed a case-control study with the purpose of establishing the pressure patterns in the soles of the feet of patients with ankle osteoarthritis, determining whether the pattern changed after treating the arthritis with ankle joint fusion (arthrodesis), and whether the change is significant. We also studied the benefits of ankle fusion with respect to the Short-Form 36-item Health Survey and the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale. The study included 18 participants (9 in the study group and 9 in the control group) to reach statistical significance with a 95% confidence interval (CI). A demonstrable increase was found in both forefoot and hind-foot pressures in the study group preoperatively compared with the control group. Also, a demonstrable increase was found in the pressure in both the forefoot (mean difference 50.56 ± 267.39 kPa) and the hindfoot (mean difference 57.44 ± 160.27 kPa) from preoperatively to postoperatively. This difference was not statistically significant (p = .59 [t(8) = 0.57]; 95% CI 256.10 to -154.98) for the forefoot pressures and for the hindfoot pressures (p = .31 [t(8) = 1.08]; 95% CI 180.64 to -65.76). The Short-Form 36-item scores significantly improved from preoperatively to postoperatively (p = .000054 for the physical component and p = .018 for the mental component). The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale score also improved significantly (p = .0000005). The foot pressures, as measured by using the insole sensors, showed an increase in forefoot and hindfoot pressures that was not statistically significant.
我们进行了一项病例对照研究，目的是确定踝关节骨关节炎患者足底的压力模式，确定在通过踝关节融合术（关节固定术）治疗关节炎后该模式是否改变，以及这种改变是否显著。我们还研究了踝关节融合术在36项简短健康调查和美国矫形足踝协会踝 - 后足量表方面的益处。该研究纳入了18名参与者（研究组9名，对照组9名），以在95%置信区间（CI）达到统计学显著性。与对照组相比，研究组术前前足和后足压力均有明显增加。此外，从术前到术后，前足（平均差异50.56±267.39kPa）和后足（平均差异57.44±160.27kPa）的压力也有明显增加。前足压力（p = 0.59 [t(8) = 0.57]；95% CI 256.10至 -154.98）和后足压力（p = 0.31 [t(8) = 1.08]；95% CI 180.64至 -65.76）的这种差异无统计学意义。36项简短健康调查评分从术前到术后显著改善（身体成分p = 0.000054，心理成分p = 0.018）。美国矫形足踝协会踝 - 后足量表评分也显著改善（p = 0.0000005）。使用鞋垫传感器测量的足部压力显示前足和后足压力增加，但无统计学意义。
