TOTAL ARTICULAR REPLACEMENT ARTHROPLASTY - A 3-YEAR TO 10-YEAR CASE-CONTROLLED STUDY

One hundred eighty-four cemented primary total articular replacement a rthroplasty (TARA) resurfacing total hip procedures were performed by a single surgeon from 1981 to 1985. One hundred seventy-four hips had a mean follow-up period of eight years (range, 3.5-10.4 Sears). Osteoa rthrosis was the predominant diagnosis (79%). Failure was defined as a hip needing additional surgery because of an implant failure and occu rred in 13.2% of the patients. No statistically significant difference was found between preoperative etiology, patient gender, or the side of the hip involved between the revised and unrevised patients. The re vised group was seven years younger at the time of TARA implantation t han the group that was not revised (55.7 versus 65.3 years), with sign ificance to the p < 0.01 level. Survival analysis demonstrated an 87.1 % chance of survival at seven years, decreasing to 84.5% at ten years. The cemented TARA hip replacement has a better intermediate to long-t erm success than other resurfacing designs reported using cemented fix ation. However, this does not compare favorably with the longevity of cemented Charnley total hip replacements reported at similar intervals .
