PURPOSE: The aim of this article was to evaluate the resumption of physical activity and sports after valgus osteotomy for medial femorotibial osteoarthritis. METHODS: This series is composed of 83 patients, with 27 females and 56 males. The mean age was 50.4 ± 9.53 years (32-67) at the time of operation. Before the onset of symptoms of knee osteoarthritis, four (4.8%) patients practiced a competitive sport, 44 (53%) one (or more) recreational sport on a regular basis, 17 (20%) occasionally and 18 (21.6%) did not practice any sport but were active. Sixty-two opening wedge high tibial osteotomies were performed as well as 21 double level osteotomies for severe deformity. All the osteotomies were computer-assisted in order to reach the best overcorrection. RESULTS: At a mean follow up of 5.75 ± 1.3 years (five to nine years), 71 patients (85.5%) resumed sporting activities and 66 (79.5%) felt they had found a sporting level equal to the level prior surgery. The mean Lysholm score increased from 62.51 ± 15.53 points (30-100) pre-operatively to 90.49 ± 8.62 points (55-100) postoperatively (p < 0.001). The Tegner and UCLA scores didn't decrease significantly after surgery (4.53 and 7.14 pre-operatively versus 4.1 and 6.55 postoperatively, p = 0.07 and 0.09). The mean postoperative KOO score was 73.52 ± 17.20. The frequency of sports sessions per week (2.36 ± 1.6) did not decrease significantly after surgery (2.13 sessions, p = 0.34). On the other hand, the duration of activities decreased significantly from 4.68 hours/week ± 4.25 to 3.48 hours/week (p = 0.04). Of the patients who practiced running before surgery 85% (17 of 20) were able to resume this activity. CONCLUSION: This study demonstrates that knee osteotomies for medial femorotibial osteoarthritis allow the resumption of sustained physical activity such as jogging or skiing downhill in a majority of patients.
