Total joint arthroplasty in the extremely elderly: hip and knee arthroplasty after entering the 89th year of life.

The goal of this study was to evaluate the complications and efficacy of total joint arthroplasty in the extremely elderly and compare the survival with the normal age-matched population. One hundred one joint arthroplasties (45 total knee arthroplasties [TKAs], 56 total hip arthroplasties [THAs]) were performed in 83 patients 89 years old and older. Over an average follow-up period of 2.5 years, 26 (31%) of the patients died. Three patients (3.6%) died within the first 2 months' postoperatively. The perioperative medical complication rate (excluding deaths) was 14%. Significant improvements were noted in pain scores, Harris Hip Scores, and Knee Society Scores. The survival of patients in their nineties who undergo total joint arthroplasty is at least equal to the survival of an age-matched population for 2.5 years following surgery. With careful patient selection and patient care to minimize medical complications, total joint arthroplasty can be an excellent option for patients who are age 89 and older.
