[EX Q]: Question: Does partial meniscus substitution with a polyurethane scaffold improve outcome after an open-wedge high tibial osteotomy?
Answer: 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.
[EX A]:
no
