According to Dr. Gelber, you can use a knee brace for a lateral meniscus tear or a medial meniscus tear. And he specifically recommends using a knee brace for a meniscus tear after surgery (rather than as a preventative measure). “Where I use knee braces the most in relation to the meniscus is after surgery, where we can use braces to limit weight bearing bending to less than 90 degrees,” he says. “This can help prevent additional shear forces across the healing meniscus.”
