Many people can walk on a torn meniscus, but that doesn't mean it should be ignored. See a specialist if your knee catches, locks, gives way or stays swollen. Some tears heal with physical therapy, while others need arthroscopic repair to protect the knee.
Most patients start physical therapy within days of surgery. Walking without crutches usually returns within a few weeks, and return to cutting and pivoting sports typically takes about nine to twelve months, once strength and movement tests show the knee is ready.
See us promptly if your knee swells quickly after an injury, especially with a pop, or if you can't put weight on it. Get care the same day if the knee is red, hot and swollen with a fever, which can be a sign of infection.
