Knee braces do not treat meniscus tears, according to the University of Washington Department of Orthopaedics and Sports Medicine. However, after surgery to repair this injury, patients often feel more secure when wearing braces or splints for support. In addition, a post-operative brace helps protect the knee, according to WebMD.
Each knee has two menisci made of cartilage, Mayo Clinic explains. Severely twisting or rotating the knee can result in a torn meniscus. Sometimes, the tear heals with conservative treatment, including ice, rest and over-the-counter pain medication. Physical therapy improves muscle strength around the knee, providing increased stability. However, when the pain does not go away, or when the knee is inflexible and immobile, repairing the knee often requires surgery.
