To evaluate return to sport (RTS), work (RTW) and clinical outcomes following lateral closing wedge distal femoral osteotomy (LCW-DFO) for symptomatic varus malalignment.Consecutive patients who underwent LCW-DFO malalignment between 12/2007 03/2018 were included. The International Knee Documentation Committee (IKDC) Score, Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), Lysholm score, Tegner Activity Scale, visual analogue scale (VAS) pain collected preoperatively at a minimum of 24 months postoperatively. RTS RTW assessed by questionnaire.Thirty-two (mean age: 45.9 ± 12.3 years), femoral-based (6.4 3.0°), included mean follow-up 72.7 39.1 months. patient collective significantly improved in IKDC (51.8 61.8 21.5, p = 0.010; 95% CI 3-21), WOMAC (26.7 17.6 12.5 13.5; < 0.001; 21-6) (46.5 19.4 67.9 22.8 points (p 0.01; 9-31)) scores final follow-up. VAS reduced postoperatively (4.8 2.3 2.6 0.002; 0-3)). Following LCW-DFO, 96% returned sports 5.3 2.9 Yet, shift lower impact compared one year was observed, with participating number high-impact disciplines 0.024) fewer hours 0.034). Twenty-three out 11.4 10.9 weeks, 18 reporting similar or superior working ability.Undergoing isolated enabled the vast majority along significant functional improvement mid-term However, patients' expectations have be adequately managed regarding limited probability after surgery.Retrospective case series; Level IV.
