title: Function and quality of life in patients with recurvatum deformity after primary total knee arthroplasty: a review of our joint registry.
abstract: The aim of this paper is to assess function and quality of life in patients with recurvatum at 2 years after primary total knee arthroplasty. This prospective study involves 2587 total knee arthroplasty from 2004 to 2008 with 2-year follow-up. Patients' demographics, diagnosis, implants, range of motion, laxity, and knee and SF-36 scores were recorded. Recurvatum deformity of 0°, 1° to 5°, 6° to 10°, and more than 10° were classified as grades 0, 1, 2, and 3, respectively. Grade 1 had similar functional scores to grade 0 but significantly better SF1, SF4, SF5, and SF8 when compared with grades 2 and 3. Patients with mediolateral translation of more than 5 mm were more likely to have grades 2 and 3 recurvatum (P = .01), indicating global laxity. Postoperative recurvatum of more than 5° significantly impacts function and quality of life of patients.
