研究背景：患者报告的结局指标（PROM）最近被认为是全髋关节置换术（THA）后的临床结局指标。虽然各种因素都与后THA和PROMs，步态参数，这是THA后的客观评估因素的关系，仍不清楚。Research question什么是全髋关节置换术后四周PROMs和步态生物力学因素之间的关系？方法45例THA患者，男6例，女39例。THA术后4周进行三维步态分析;评估手术侧在地板反作用力垂直分量第一和第二峰值时的关节角、内部力矩和下肢功率。使用日本骨科协会髋关节疾病评价问卷（JHEQ）对PROM进行评价。性别和步态速度作为控制factors.ResultsFor的JHEQ子域，运动之间的关系进行了分析，并提取步态参数与JHEQ分数，正相关的内部膝关节伸展力矩值在第一个峰值（r = 0.347）。JHEQ与第一个峰值处的髋关节内展力矩值之间无显著相关性。精神状态与第二峰髋关节屈曲角度值呈负相关（r =-0.373），与髋关节屈曲力矩值呈正相关（r = 0.348）。JHEQ总分和精神状态与第二峰髋关节屈曲力值呈负相关（r =-0.316，-0.444）。需要进一步的研究来验证步态参数是否可以改善THA术后早期的PROM。
BackgroundPatient-reported outcome measures (PROMs) have recently been considered as indicating clinical outcomes after total hip arthroplasty (THA). Although various factors are reportedly associated with post-THA and PROMs, the relationship with gait parameters, which are objective assessment factors after THA, remains unclear.Research questionWhat is the relationship between PROMs and gait biomechanical factors four weeks after THA?MethodsForty-five patients (six men and 39 women) who underwent THA were included. Three-dimensional gait analysis was performed four weeks post-THA; joint angle, internal moment, and power of the lower extremity at the first and second peaks of the vertical component of the floor reaction force were assessed for the operated side. PROMs were evaluated using the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (JHEQ). The relationship between the JHEQ score and extracted gait parameters was analyzed using gender and gait speed as control factors.ResultsFor the JHEQ sub-domain, movement was positively correlated with the internal knee extension moment values at the first peak (r = 0.347). There was no significant correlation between JHEQ and the internal hip abduction moment value at the first peak. Mental status was negatively correlated with the hip flexion angle value at the second peak (r = −0.373), and positively correlated with the hip flexion moment value (r = 0.348). Total JHEQ scores and mental status were negatively correlated with the power of hip flexion value at the second peaks, respectively (r = −0.316, −0.444).SignificanceThe results of this study may provide recovery guidelines to be used as an index for gait assessment in the early post-THA period. Further studies are needed to verify whether gait parameters can improve PROMs in the early post-THA period.
