Knee joint recurvation due to non-fixed pathologies in the adjacent joints or secondary changes in musculotendinous and ligamentous structure of the joint were corrected by orthopedic and rehabilitative orthoses in addition to physiotherapeutic procedures.
Late-term outcomes of orthopedic and surgical treatment of the knee joint recurvation were followed-up for 1-8 years.
Diagnosis: ICP, moderate spastic diplegia, recurvation of both knee joints--Ist degree on the right and IIIrd degree on the left.
In particular, to differentiate knee joint recurvation caused by the equinovarus the crural extension is needed as the common center of mass projection will pass anterior to rotation center in the knee joint.
To differentiate primary pathological knee joint recurvation due to its anatomical alterations from the one caused by the equinovarus an infant stands on toe, the degree selected in accordance with severity of the equinovarus.
Presence of dynamic recurvation is defined by comparative analysis of gait of patients using orthoses and without them.
It should be noted that the knee joint recurvation can form due to anatomical alterations in the joint per se, including weakness of ligamentous apparatus or physiological posterior slanting of the tibial articular surface.
Method of motor abnormality correction is chosen following elucidation of the knee joint recurvation causes in children with ICP.
