“…Such compensatory strategies increase the risks of low back pain and muscle imbalance, which are recurrent concerns for individuals with lower limb amputations. Moreover, degenerative changes at intact joints, in particular hip osteoarthritis of the sound limb, could be worsened by such compensations [34,[44][45][46]. The modifications in gait kinematics found in the present study after osteointegration surgery suggest an overall improved movement quality and a reduced risk of the comorbidities usually associated with the transfemoral amputee condition.…”

The aim of the present case report was to provide a longitudinal functional assessment of a patient with transfemoral amputation from the preoperative status with socket-type prosthesis to one year after the osseointegration surgery. A 44 years-old male patient was scheduled for osseointegration surgery 17 years after transfemoral amputation. Gait analysis was performed through 15 wearable inertial sensors (MTw Awinda, Xsens) before surgery (patient wearing his standard socket-type prosthesis) and at 3-, 6-, and 12-month follow-ups after osseointegration. ANOVA in Statistical Parametric Mapping was used to assess the changes in amputee and sound limb hip and pelvis kinematics. The gait symmetry index progressively improved from the pre-op with socket-type (1.14) to the last follow-up (1.04). Step width after osseointegration surgery was half of the pre-op. Hip flexion-extension range significantly improved at follow-ups while frontal and transverse plane rotations decreased (p < 0.001). Pelvis anteversion, obliquity, and rotation also decreased over time (p < 0.001). Spatiotemporal and gait kinematics improved after osseointegration surgery. One year after surgery, symmetry indices were close to non-pathological gait and gait compensation was sensibly decreased. From a functional point of view, osseointegration surgery could be a valid solution in patients with transfemoral amputation facing issues with traditional socket-type prosthesis.

“…Alignment factors include the angular positioning of the knee, ankle, and foot, as well as the sagittal, coronal, and transverse planes. Precise alignment helps maintain proper joint mechanics, reduces stress on the residual limb, and improves stability and balance during walking and other movements (Schmalz et al, 2002;Zhang et al, 2019Zhang et al, , 2020. Prosthetic limbs must replicate the natural joint mechanics of the lower limb to ensure smooth and efficient movement.…”

“…Essential for superior performance and comfort of prosthetic limbs, proper distribution of loads and weight-bearing capabilities are of paramount importance. Designers must consider factors such as the alignment of the prosthetic limb, joint biomechanics, and gait patterns (Dipl-Ing et al, 2012;Simon et al, 2016;Edelstein and Chui, 2019;Mohamed and Appling, 2019;Zhang et al, 2019Zhang et al, , 2020Kobayashi et al, 2020;Siddikali and Sreekanth, 2020;Butowicz et al, 2021;Jarvis et al, 2021;Köhler et al, 2021;Pinhey et al, 2022). Load distribution plays a pivotal role in prosthetic limb design.…”

This literature review on the design of amputated lower limbs has covered various aspects related to prosthetic limb design. It has highlighted the need for continuous improvement and innovation in order to enhance user satisfaction, mobility, and overall quality of life. Biomechanical factors such as gait analysis, joint range of motion, force distribution, and energy efficiency were identified as crucial considerations in amputated lower-limb design. Socket design principles, focusing on comfort and proper load distribution, were found to be essential for achieving a well-fitting and functional prosthetic limb. Emerging technologies, including advanced materials, robotics, neural interfaces, and sensor technology, were explored as potential avenues for improvement. These technologies showed promise in enhancing functionality, control, and sensory feedback in prosthetic limbs. A user-centric approach was emphasized, involving users in the design process and incorporating their feedback and preferences. Affordability and accessibility were highlighted as significant concerns, calling for the development of cost-effective solutions. Long-term performance and durability were also emphasized, stressing the need for robust materials and quality control processes. The integration of neural interfaces and sensory feedback posed opportunities and challenges for achieving more natural limb control and sensation. To sum up, this literature review has furnished valuable perspectives on amputated lower-limb design, underscoring the significance of refining design principles, accounting for biomechanical variables, embracing emerging technologies, and integrating user input. Future directions include addressing affordability, long-term performance, and neural integration while leveraging advancements in materials, technology, and user-centered design.

“…Authors suggested that prosthetic misalignments increase the loading on the contralateral limb and, in the same way, the stance phase time and vertical GRF peak were different between misalignments and nominal alignments. Zhang et al [5] identified for transfemoral amputees an effect of the prosthetic misalignment in the intact hip and knee joint moments by following a within-subject analysis. In general, earlier studies have found a significant relationship between GRF parameters and prosthetic alignment conditions.…”
