Evaluation a range of the motion of knee during femoral lengthening by Ilizarov method.

Background. Extensory contracture of the knee joint is a constant problem during thigh lengthening procedures. Its occurrence is dependent on such factors as rehabilitation, the construction of the Ilizarov apparatus, the extent of the lengthening, and the etiology of the shortening. Material and methods. Between 1998 and 2001, 34 children were treated for thigh shortening. Contracture occurred in all cases. Results. The dynamics of the lengthening process were strictly associated with the development and elimination of any contracture that appeared. If the indicated rules are followed, extensory contracture of the knee joints always resolved within several months after removal of the Ilizarov apparatus. Conclusions. The importance of the proper rehabilitation program is equal to that of the surgical procedure. Limiting the number of impulses and localizing them is helpful in later rehabilitation.
