Methods: Sixty patients with symptomatic varus knees those who underwent open-wedge high tibial osteotomies were prospectively studied. In 30 patients, the medial meniscus was left with a defect larger than 25mm (Group M). An Actifit® device was implanted (Group A) in the remaining 30 patients. Patients were functionally evaluated with WOMET, IKDC and VAS. Patient satisfaction was graded from 0 (not satisfied) to 4 (very satisfied). Results: Both groups were comparable preoperatively. They had similar follow-up periods (31.2months; range 24-47.5; n.s.). WOMET improved a mean of 53.4±8.4 and 42.4±17.2 points in Groups M and A, respectively (p=0.002). IKDC improved a mean of 56.7±12 and 50.3±15.6 points in Groups M and A, respectively (n.s.). VAS dropped 5.9±2.1 and 4.7±2.8 points in Groups M and A, respectively (p=0.006). Patient satisfaction averaged 3.3±0.8 and 3.3±1 in Groups M and A, respectively (n.s.). Conclusions: Patients with symptomatic varus knees were treated with open-wedge high tibial osteotomies, and a meniscectomy was improved more at short-term follow-up in most of the evaluated functional scores than those patients with concomitant implantation of a medial Actifit® implant. However, there was no difference in terms of patient satisfaction with the procedure. Based on the short-term functional results of this study, no data were provided to support medial meniscal substitution with a polyurethane scaffold when an open-wedge high tibial osteotomy is being performed. Level of evidence: Prospective comparative study, Level II.
