Three-dimensional gait characteristics of patients after unilateral total knee arthroplasty

Abstract: The purpose of this study is to evaluate the gait characteristics of bilateral limbs after unilateral total knee arthroplasty (TKA) using three-dimensional (3D) dynamic capture technology. Forty-two patients who underwent TKA were selected from the Orthopedic Medical Center of The Second Hospital of Jilin University from November 2018 to May 2019. We used a 3D dynamic capture system to measure the gait characteristics of patients at 3 months after TKA. The data, including relative position and direc… Show more

“…While this offers a patient-specific goal for recovery, it does not account for the effect of pre-operative pain and deformity on gait dysfunction and walking discomfort, nor how these variables may influence a patient’s self-selected intensity and duration or the efficiency of physical activity [ 45 ]. For example, advanced OA patients present with lower limb kinematic and kinetic asymmetries during walking that are not corrected by TKA [ 13 , 14 , 15 ], and gait asymmetries in step length and excursion remain despite pain alleviation with arthroplasty [ 13 , 46 ]. This is possibly due to neuromuscular dysfunctions that have embedded in motor programming over time [ 47 ].…”

“…Step counts are reported to recover as fast as 6 weeks following TKA [ 11 ]. However, range of motion deficits and gait asymmetries persist for at least 3 months post-operatively [ 13 , 14 , 15 ]. Therefore, measuring step count alone provides only a partial indication of physical function recovery following TKA.…”
