The kinematics and stability of single-radius versus multi-radius femoral components related to Mid-range instability after TKA

There continues to be some dissatisfaction with the function of total knee arthroplasties (TKA). “Mid‐range instability” has been linked to multi‐radius femoral components allowing transient ligament slackness and instability during knee flexion. Single‐radius designs have been introduced to avoid t...
