Majority of patients with Progressive Collapsing Foot Deformity(PCFD) have symptoms pertaining to the knee. Malalignment at the foot will have effects on the alignment of the knee. In this case control study, we compare the alignment of the knees between patients with PCFD and controls.
Sixty subjects, 30 PCFD and 30 controls, underwent radiographs in which the tibiofemoral angle and radiological parameters of PCFD were assessed. Parameters of PCFD were correlated with the tibiofemoral angle.
Mean tibiofemoral angle was 3.8° among the cases and 4.8° among the controls which was statistically significant(P = 0.001). Varus knee alignment was seen in 41 out of 60 limbs with PCFD which was statistically significant(P < 0.001). The tibiofemoral angle correlated significantly with the Meary angle(P = 0.03) and the talonavicular coverage angle(P = 0.003).
PCFD is associated with varus knee malalignment. This varus deformity early in adulthood may lead to deleterious effects like medial compartment osteoarthritis in later life. Early intervention for such patients may help avoid this knee damage.

大多数进行性足塌陷畸形（PCFD）患者有与膝关节相关的症状。足部的力线不正会影响膝关节的力线。在这项病例对照研究中，我们比较了PCFD患者与对照组的膝关节力线。
60名受试者，30名PCFD患者和30名对照组，接受了X线检查，评估了胫股角和PCFD的放射学参数。PCFD的参数与胫股角相关。
病例组的平均胫股角为3.8°，对照组为4.8°，差异有统计学意义（P = 0.001）。60条患有PCFD的肢体中有41条出现膝内翻力线，差异有统计学意义（P < 0.001）。胫股角与Meary角（P = 0.03）和距舟覆盖角（P = 0.003）显著相关。
PCFD与膝内翻力线不正有关。这种成年早期的内翻畸形可能会在以后的生活中导致诸如内侧间室骨关节炎等有害影响。对此类患者进行早期干预可能有助于避免膝关节损伤。
