Use of a new high-activity arthroplasty score to assess function of young patients with total hip or knee arthroplasty.
The High-Activity Arthroplasty Score (HAAS) was specifically developed to assess subtle variations in functional ability after lower limb arthroplasty with particular regard to highly functioning individuals. The score was a 4-item self-assessment measure covering the 4 domains of walking, running, stair climbing, and general activities, with a possible score ranging from 0 to 18 points. The score was validated in 22 patients (total hip arthroplasty [THA], n = 11; total knee arthroplasty [TKA], n = 11) by comparison with the Oxford, Knee Society, Harris Hip, and Short WOMAC scores. The HAAS was then administered to 152 high-functioning arthroplasty patients (THA, n = 99; TKA, n = 53), all younger than 66 years. The HAAS produced a much wider range of scores, allowing greater differentiation of level of function between patients in assessing performance after TKA or THA.
