Any dislocation should be reduced as soon as reasonably possible. While a joint is dislocated, the metabolism of its hyaline cartilage is disturbed and synovial fluid functions are impaired. Hyaline cartilage may begin to degenerate during this brief period, and irreversible changes rapidly occur. Consequently, when old unreduced dislocations are finally reduced, normal and painless joint motion and function should not be expected.
