Background: The differences in bony alignment of the lower extremities during gait compared to standing remain unclear.
Objective: This study aimed to evaluate three-dimentional (3D) lower extremity alignment in healthy elderly individuals during the stance phase of gait and compare it with static standing alignment.
Methods: Thirty-four knees (9 females, 8 males; mean age 73.
Article Synopsis
- Ongoing debate exists regarding the benefits of patellar resurfacing in total knee arthroplasty, especially with newer implant designs that are patella-friendly.
- The study compared postoperative outcomes for two groups: those who underwent patellar resurfacing (PR group) and those who did not (NPR group) using the same implant design, analyzing various demographic and outcomes data.
- The findings indicated no significant differences in recovery metrics between the two groups, but the NPR group showed earlier improvements in knee function, implying that patellar resurfacing might not be essential with modern knee prosthetic designs.
Background: Accurate measurement of bone alignment of the knee during walking provides ideal clinical information for diagnosis and treatment of knee joint disorders. To bring this ideal closer to clinical reality, we developed an image matching technique to measure the three-dimensional (3D) position of bones using anteroposterior radiography during the stance phase of treadmill walking.
Objective: To develop and validate an image matching method for evaluation of 3D knee alignment using anteroposterior radiography of artificial femoral and tibial bones.
Medial pivot total knee arthroplasty implants are designed to function in a similar manner to that of the native knee with a relatively fixed medial center of rotation and a less conforming lateral compartment that follows an arcuate path. Medial pivot implants in total knee arthroplasty have increased in popularity with many companies offering medial pivot or retrofitted medial congruent implants, and there are variations between the various medial pivot and medial congruent implants. Existing literature on medial pivot implants have demonstrated high survivorship and patient outcomes.

The purpose of this study was to clarify the stability of implanted knees during walking by comparing differences in dynamic instability during knee acceleration between individuals with or without previously experienced subjective instability, as measured by self-reported questionnaire.
Materials And Methods: We examined 92 knees with medial pivot implants.
