Post-operative
rehabilitation should incorporate strategies to improve knee motion as the risk
of contralateral TKS found to increase with altered movement patterns after
surgery.
According to recent research results published in the Journal of Orthopaedic Research, individuals who have stiffer gait walking patterns showed higher chances of second total knee arthroplasty (TKA).
The contralateral limb is linked to the altered and asymmetrical movement patterns following the unilateral TKA, which overload the contralateral joints. The present study explored the association of biomechanical factors following the unilateral TKA with future contralateral TKA.
A total of one
hundred fifty-eight participants were selected and re-contacted for mean 5.89
years follow-up to evaluate if they had encountered a contralateral TKA. The
participants who did and did not go through contralateral TKA at follow‐up were compared for biomechanical variables from gait at baseline
using one‐way ANOVAs. The odds ratio was estimated for variables attained to
be important in the ANOVA models. Participants who went through contralateral
TKA had less knee extension excursion and less knee flexion excursion at
baseline on the treated side during walking. Also, less knee flexion excursion
on the contralateral limb at baseline was seen among the persons who went
through contralateral TKA. Further, a 9.1% reduction in risk of future
contralateral TKA was noticed for every additional degree of knee flexion
excursion on the contralateral knee at baseline.
