We performed total hip arthroplasty (THA) in 10 patients 80-years-old and older between 1998 and 2002. Seven hips were diagnosed with osteoarthritis, and 4 hips rapidly destructive coxopathy (RDC). The age of the patients operated on ranged from 80 to 85 years old (average, 81.4 years). The follow-up period was from 4 months to 4 years (average, 2 years and 6 months).
The clinical results were evaluated with the JOA scoring system score. The average value of pain subscore improved remarkably in comparison to the preoperative score. The average gait and ADL subscores, however, did not improve as much. Poor preoperative ADL values strongly influenced postoperative ADL improvement. There were no complications.
Patients with preoperative muscle strength deterioration, especially in cases of RDC, had little improvement in ADL after THA. As a result, we believe that THA should be performed as early as possible on patients 80-years-old and older.
