Purpose: To compare the clinical and radiological outcome of open-wedge high tibial osteotomy (OWHTO) with allogenous bone chips to a control group without bone void filler. The focus was on the rates and timelines of return to work (RTW) and return to sports (RTS), given the significance of these factors for the satisfaction of young and active patients. Methods: One hundred and ninety-five cases of OWHTO (112 cases with allograft vs. 83 cases without graft) with a follow-up of 17 +/- 4.8 months were included in this retrospective analysis. Various metrics were investigated, including time to return to full weight bearing, RTW and RTS rates and timelines, International Knee Documentation Committee (IKDC) Score, Cincinnati-Sportsmedicine and Orthopaedic Centre Score and Tegner Score. The time to bone union was determined on radiographs taken at 6, 16, 28 and 53 weeks. Results: Patients returned to full weight bearing after 8.8 +/- 4.8 weeks. RTW was possible for 92.8% after 13.7 +/- 12.3 weeks. 96.2% returned to sports after 22.7 +/- 8.3 weeks, but the number of disciplines and workouts per week diminished (p < 0.001, p = 0.006). A shift to low-impact and recreational sports was observed. Patients with allograft filling had earlier bone union (21 +/- 12.3 vs. 31.9 +/- 14.2 weeks, p < 0.001) and returned faster to full weight bearing (8.2 +/- 4.5 vs. 9.8 +/- 5 weeks, p = 0.013). There was no difference between groups in the IKDC Score (69 +/- 17.2 vs. 69.9 +/- 15.2, p = 0.834), Cincinnati-Sportsmedicine and Orthopaedic Centre Score (68 +/- 18.3 vs. 69.4 +/- 18.2, p = 0.698) and Tegner Score (3.8 +/- 1.5 vs. 4 +/- 1.5, p = 0.246). Conclusion: Allograft filling leads to faster bone union and return to full weight bearing but showed no significant advantage in terms of RTW/RTS, overall patient satisfaction and functional scores. The decision for or against filling the osteotomy gap, therefore, remains a case-by-case decision.
