The meniscus is cartilage that provides a cushion between the femur (thigh bone) and the tibia (shin bone). A torn meniscus causes weakness in the affected knee. After surgery to repair a meniscal tear, patients receive physical therapy to strengthen the knee. Therapy can last anywhere from three weeks to four months.
During the restorative phase of physical therapy, patients work on strengthening muscles that support the knees, primarily the quadriceps and the hamstrings. The goal is for the patient to regain normal mobility, such as the ability to sit in and get up from a chair, or to go up and down stairs.
