Abstract

Objective

To investigate the gait modi?cation strategies of knee and core in patients after right ACL reconstruction for 2 years.

Methods

Thirty patients after right ACL reconstruction for 2 years and thirty healthy individuals were recruited to undergo 3-dimensional gait analysis.A 3D optical video motion capture system was used to record coordinate data from reflective markers positioned on subjects as they walked. Spatiotemporal gait and kinematic and kinetic variables of knee,trunk, pelvis and hip were calculated and further analyzed.
Result: The right side step length ,left side stride length,both side forward velocity ,both side step cadence ,both side percentage of swing phase of postoperative patients less than healthy controls(P<0.05). The left side and right side percentage of support phase of postoperative patients more than healthy controls(P<0.05). The maximum of internal and external rotation angles of right knee of postoperative patients more than healthy controls(P<0.05). During left support phase, the maximum of left knee flexion moment and left hip extension moment of postoperative patients less than healthy controls(P<0.05), and the maximum of left hip flexion moment of postoperative patients more than healthy controls(P<0.05).During right support phase, the maximum of right knee internal rotation moment and right hip adduction moment of postoperative patients more than healthy controls(P<0.05). During left support phase, the maximum of trunk anterior lean angles and trunk forward rotation angles of postoperative patients more than healthy controls(P<0.05), and the maximum of trunk posterior lean angles and trunk left lean angles of postoperative patients less than healthy controls(P<0.05). During right support phase, the maximum of trunk anterior lean angles of postoperative patients more than healthy controls(P<0.05), and the maximum of trunk posterior lean angles of postoperative patients less than healthy controls(P<0.05). During left support phase, the minimum of pelvis anterior tilt angles of postoperative patients more than healthy controls(P<0.05), and the maximum of pelvis left tilt angles of postoperative patients less than healthy controls(P<0.05). During right support phase, the maximum of pelvic left tilt angles of postoperative patients more than healthy controls(P<0.05), and the maximum of pelvic forward rotation angles of postoperative patients less than healthy controls(P<0.05).

Conclusion

These findings suggest that special and bilateral gait modification strategies of core and knee are apparent in patients after right ACL reconstruction. Some of these data of postoperative patients are still different from normal level. The results of this study may be helpful for improving the rehabilitation of ACL reconstruction.
