Detailed Instructions: In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Q: Context: The aim of the study was to determine whether medial meniscal substitution with a polyurethane scaffold (Actifit(®️)) improves the outcome of medial meniscal-deficient varus knees undergoing open-wedge high tibial osteotomy.', '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 25 mm (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).', 'Both groups were comparable preoperatively. They had similar follow-up periods (31.2 months; 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.).\Question: Does partial meniscus substitution with a polyurethane scaffold improve outcome after an open-wedge high tibial osteotomy?
A:
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.
