Hi sana,
mobilization is permitted even with a meniscal injury.
If you don't know the mulligan tecnique I'd suggest you to work hard on flex and ext of the knee(expecially on the ext because 90 degree in flex and 10 degree in ext are the minimum to keep on doing normal activities such as walking for example). Don't overstress the knee with fast and rude movement but act gently with decision because Pain could be caused by adhesions or inflamations.WOrk on the rotations with the knee bend at 70 degrees because knee,during the movement of flex-ext ,does a little rotation that you can help with.I hope to have been helpful.Don't hesitate to write me for everything: [email protected]
Bye
