They were allocated into 3 groups according to the duration of symptoms before surgery. Group A with symptoms lasting up to 24 months, B with 25–48 months and C with symptoms lasting for more than 48 months. The average age at the time of the operation was 68.9, 72.6 and 71.3 years, respectively. Forty-eight patients died and 18 refused or were not able to participate in the study. The average time of follow-up was 43.3 months, 42.2 in group A, 47.4 in B and 42.8 in C. No significant differences were noticed in the demographic, anesthetic and surgical parameters among the 3 groups. There were no mortality cases in the immediate postoperative period. The overall complication rate was 43.5%, nearly identical in all 3 groups. Two patients had cerebrovascular accident and 5 had myocardial ischemia but no one turned into infarction. Mild complications included 11 urinary retention, 24 urinary tract infections and 11 patients with superficial wound infection. Twenty-two patients were re-operated along the follow-up period. There was remarkable improvement in the perception of pain, walking distances and in the ability to perform basic activities of daily living in all 3 groups. Self-assessment of the final results disclosed 70% satisfied patients in group A, 67% in B and 67% in C.
