Furthermore, in a pilot study, this algorithm, called complementary limb motion estimation (CMLE), was applied to control an active knee
exoprosthesis.
About 1 year after the initial diagnosis, a knee disarticulation was performed and the patient was supplied with an
exoprosthesis. In this case, authors have discussed that using a prosthesis system instead of the allograft might have saved the limb of their patient [10].
The
exoprosthesis was set up such that in the coronal (frontal) plane, the long axis of the
exoprosthesis was in line with the abutment; in the sagittal plane, the long axis of the
exoprosthesis was vertical at midstance; and in the transverse plane, the foot was parallel to the nominal direction of progression at midstance (i.e., neither in- or out-toed).
(35,36) Osseointegration avoids common socket complications by using direct skeletal attachment of an
exoprosthesis to the residual limb (35) and has demonstrated success in transhumeral, transtibial and transfemoral amputations.
As a result of an increased desire for functionality for patients with transfemoral, transhumeral, and transtibial amputations [3,9-11], osseointegration technology has been developed for direct skeletal attachment of an
exoprosthesis to the residual limb.
