Abstract
Intracondylar fractures of the proximal tibia have presented perplexing problems to the orthopaedic surgeon over the years. Much controversy still exists over the amount of incongruity which can be present in a joint without the eventual development of degenerative joint disease. One factor which is perhaps universally accepted is that prolonged immobilization of the knee joint in the presence of an intraarticular fracture can be damaging and that in the presence of incongruity a fully mobile joint is less likely to undergo degeneration.
