CONCLUSION
Depending on the degree of tibial deformity,
range of motion, position of the patella and
specific problems after an osteotomy total
knee arthroplasty can be more difficult if it is
the second operation after high tibial osteo-
tomy. But the degree of difficulty differs and
necessitates a classification of the knee befo-
re total knee arthroplasty. We hypothesize
that our classification system can help to
have realistic expectations according to diffi-
culty of the operation and outcome of TKA
after HTO.
