I had knee surgery to remove 20% of my meniscus 2 months ago. while doing therapy at days my knee has some bruising and is inflated. what should i do?

Be patient: It is normal to have some swelling even 2 months after surgery such as a menisectomy. Make sure you follow the rice protocol - rest, ice, compression and elevation. The bruising could be just overdoing it at therapy. If the swelling persists or worsens, make a follow up appointment with your surgeon.

Evaluation: Contact your surgeon. May be you have infection, additional injury or overdoing physical therapy.
