“… 1 , 2 Although TKA can lead to decreased pain, increased knee range of motion (ROM), and eventually, improved physical function and quality of life (QOL), 3 physical function (e.g., quadriceps and hamstring strength, and knee ROM) decreases immediately after TKA. 4 , 5 A stiff knee gait (SKG), in which there is reduced knee flexion during walking, 6 , 7 increases energy cost and decreases walking speed. 8 It has previously been revealed that there is a temporary postoperative decrease in walking ability, including walking speed, followed by a recovery time of several months to 1 year.…”

The Honda Walking Assist® (HWA) is a light and easy wearable robot device for gait training, which assists patients’ hip flexion and extension movements to guide hip joint movements during gait. However, the safety and feasibility of gait training with HWA after total knee arthroplasty (TKA) remains unclear. Thus, we aimed to evaluate the safety and feasibility of this gait training intervention using HWA for a patient who underwent TKA. The patient was a 76-year-old female who underwent a left TKA. Gait training using HWA was conducted for 18 sessions in total, from 1 to 5 weeks after TKA. To verify the recovery process after TKA surgery, knee function parameters and walking ability were measured at pre-TKA and 1, 2, 4, and 8 weeks after TKA. The gait patterns at self-selected walking speed (SWS) without HWA at pre- and 5 weeks after TKA were measured by using 3-dimensional (3D) gait analysis. The patient completed a total of 18 gait training interventions with HWA without any adverse complications such as knee pain and skin injury. The postoperative knee extension range of motion (ROM), knee extension torque, SWS, and maximum walking speed were remarkably improved. Regarding gait kinematic parameters, though this patient had a characteristic gait pattern with decreased knee ROM (called stiff knee gait) preoperatively, the knee flexion angle at 5 weeks after TKA showed knee flexion movement at loading response phase (LR; called double knee action), increased knee ROM during gait, and increased knee flexion angle at swing phase. In this case, the gait training using HWA was safe and feasible, and could be effective for the early improvement of gait ability, hip function, and gait pattern after TKA.

“…Benedetti (2003) suggested that many patients do not regain normal joint function following TKA even during low-level activities such as walking [18]. Even years post-operatively, patients exhibit slower gait, decreased stride length, and abnormal flexion/extension moments particularly during the stance and swing phases [11,17,18].…”

“…Typically, kinematic analyses are carried out within gait laboratories and require specialist equipment such as force plates and 3-dimensional motion capture systems. Such systems can uncover detailed information about movement kinetics and kinematics [11] but are hugely expensive and difficult to access in routine orthopaedic clinical practice. Distinct mechanical patterns associated with knee replacement instability have been demonstrated using a simple loaded extension of the knee [12].…”

“…Nolte et al [ 30 ] pointed out that kinematic alignment which is based on the alignment of the prearthritic lower limb can allow better restoration of knee physiological function. Ullrich et al [ 31 ] studied the long-term data of gait characteristics and moment-knee angle relations in female total knee replacement patients, and they found that the patients showed significant gait deficits during constant and self-selected walking speeds and lower average absolute values in the moment-knee angle relations of the knee extensors and flexors. Baldwin et al [ 32 ] developed subject-specific finite element models from imaging data.…”

Total knee replacement (TKR) has been performed for patients with end-stage knee joint arthritis to relieve pain and gain functions. Most knee replacement patients can gain satisfactory knee functions; however, the range of motion of the implanted knee is variable. There are many designs of TKR implants; it has been suggested by some researchers that customized implants could offer a better option for patients. Currently, the 3-dimensional knee model of a patient can be created from magnetic resonance imaging (MRI) or computed tomography (CT) data using image processing techniques. The knee models can be used for patient-specific implant design, biomechanical analysis, and creating bone cutting guide blocks. Researchers have developed patient-specific musculoskeletal lower limb model with total knee replacement, and the models can be used to predict muscle forces, joint forces on knee condyles, and wear of tibial polyethylene insert. These available techniques make it feasible to create customized implants for individual patients. Methods and a workflow of creating a customized total knee replacement implant for improving TKR kinematics and functions are discussed and presented in this paper.
