Work intensity and quality of life can be restored following double-level osteotomy in varus knee osteoarthritis

Purpose The purpose of this study was to assess changes in health-related quality of life (HRQL) and work intensity following double-level knee osteotomy (DLO). It was hypothesized that postoperative HRQL would be comparable to that of the general population and that work intensity can be restored i...

Description
Summary:Purpose The purpose of this study was to assess changes in health-related quality of life (HRQL) and work intensity following double-level knee osteotomy (DLO). It was hypothesized that postoperative HRQL would be comparable to that of the general population and that work intensity can be restored in the short term. Methods Twenty-four patients (28 varus knees; mechanical tibiofemoral angle: −11.0 ± 3.0° (−6.0 to −17.0), age: 49.1 ± 9.5 (31–65) years) who underwent DLO were included. The duration the patients were unable to work was evaluated. HRQL was measured with the SF-36 questionnaire, which consists of a physical (PCS) and mental component summary score (MCS). The pre- to postoperative changes in the PCS and MCS were analysed. The PCS and MCS were also compared to those of the general population, who has a reference score value of 50 points. The work intensity measured with the REFA classification and the Tegner activity scale were assessed preoperatively and at the final postoperative follow-up examination (18.0 ± 10.0 (5–43) months). Results The duration that the patients were unable to work was 12.2 ± 4.4 (6–20) weeks. The PCS improved from 32.1 ± 11.3 (14.5–53.3) preoperatively to 54.6 ± 8.5 (25.2–63.7) ( p
