Recreational activity after cementless total hip arthroplasty in patients older than 75?years

摘要

Abstract Introduction This retrospective study aimed to compare activity levels before and at mid-term follow-up after primary cementless total hip arthroplasty (THA) in patients older than 75?years.Materials and methods A cohort of 79 patients with a mean age at surgery of 78?years (range 76–84?years) was evaluated 6.3?years (range 4–8?years) after cementless THA due to osteoarthritis and was followed up with a questionnaire to determine their activity level. Pre- and post-operative recreational activities were assessed at routine follow-up using the University of California, Los Angeles activity score, and the Schulthess Clinic sports and activity questionnaire. Post-operative health-related quality of life was measured using Veterans Rand 12-item survey (VR-12).Results Six years after THA, 72 of preoperatively active patients had returned to activity. Comparing activity preoperatively (before the onset of symptoms) and 6?years after THA, the number of disciplines and session length has decreased significantly. A significant decline in high-impact activities was observed, while participation in low-impact activities significantly increased.Conclusion The majority of patients maintained a recreational activity level in the mid-term after primary cementless THA. However, a change in disciplines toward low-impact activities was observed.
