In a bruised or torn meniscus, one should avoid doing exercises which involve knee flexion (bending of knee). Perhaps the second exercise you mentioned, ie "knee to chest exercise" require you to bend the knee. You must stop this exercise. Please do the exercises keeping your knee straight.
My suggestion would be:
- Straight leg raise- lie down on your back and raise your legs keeping the knee straight. hold it for 5 seconds and lower it. repeat it for at least 20 times.
- lie on your left side and again do straight leg raise.
- lie on your right side and repeat it.
- Leg press- Keep a pillow beneath your knee and press the pillow. hold it for 5 sec. repeat it for as many as times you could.
Hope this helps. All the best.
