Patient reported activity after revision total knee arthroplasty.
A total of 335 patients underwent revision total knee arthroplasty (TKA) between 1995 and 2000 with a single implant design. These patients were surveyed regarding clinical outcome and activity level; 206 patients responded (62%). Average age at revision TKA was 69 years (range, 31-87 years). Average follow-up was 5.6 years (range, 3-9 years). Average University of California at Los Angeles activity level rating was 6.7 (range, 2-10). Satisfaction with activity level after TKA was 77%. Among the respondents, 126 (61%) indicated that their activities were limited by other joints. Patients younger than 70 years had higher University of California at Los Angeles activity level scores (P=.054) and Knee Society function scores (P < .001), but there was no difference in self-assessment of activity level vs peers (P = .81) compared to those older than 70 years. Patients most commonly reported participating in walking, stationary biking, swimming, and dancing. Twenty-three (12%) patients reported participating in heavy manual labor or sports deemed "not recommended" by Knee Society published guidelines.
