surgical remodelling of a diseased joint. To prevent the ends of the bones fusing after the operation, a large gap may be created between them (gap or excision arthroplasty), a barrier of artificial material may be inserted (interposition arthroplasty), or one or both bone ends may be replaced by a prosthesis of metal or plastic (replacement arthroplasty). This operation may replace both joint surfaces (total arthroplasty) or only one (see hemiarthroplasty). See also hip replacement.
