Side-to-side differences of three-dimensional knee kinematics during walking by normal subjects.

Ino T, Ohkoshi Y, Maeda T, Kawakami K, Suzuki S, Tohyama H - J Phys Ther Sci (2015)

Bottom Line: [Purpose] The purpose of this study was to determine the normal range of the side-to-side difference in three dimensional knee kinematics measured by the point cluster technique (PCT). [Subjects] The subjects were twenty-one healthy normal volunteers without knee pain or an episode of injury to the legs. [Methods] The subjects were tested bilaterally at a self-selected normal walking speed and six degrees of freedom knee kinematics were measured using the PCT, and the 95% confidence intervals of the average side-to-side differences in flexion-extension (FE), adduction-abduction (AA), internal-external (IE) rotation, and anterior-posterior (AP), medial-lateral (ML), superior-inferior (SI) translation in each stage of the gait cycle were determined. [Results] The average side-to-side differences and their 95% confidence intervals in rotation/translation in each stage of the gait cycle were determined.The side-to-side differences in AA rotation and AP translation of the tibia were significantly larger in the swing phase than in the stance phase. [Conclusion] The side-to-side differences in AA rotation and AP translation were highly dependent on the stage of the gait cycle.Therefore, the normal ranges of the side-to-side differences in knee kinematics in each stage of the gait cycle, in particular AA rotation and AP translation of the tibia, is useful information for evaluating knee kinematics during walking.

Mentions: For clinical application, the knee kinematics of a case with the posterior cruciateligament injury (PCL) were also evaluated. A 37 year-old male suffered a knee injury whileplaying rugby football. The case showed grade-3 positive in the posterior drawer test, andposteromedial rotatory instability11). TheMRI images indicated a PCL injury. At two months after injury, evaluation of 3-D kinematicsduring walking was performed using the same procedures described above. Based on theside-to-side differences of kinematic data during each stage of gait, the tibia of theinjured leg was shifted posteriorly in AP translation during 20% to 60% walking cycle, andshifted internally in IE rotation during 0% to 60% gait cycle (Fig. 3Fig. 3
