Hi - I've Had Arthroscopic Knee Surgery For Tears Of

Hi - I've had arthroscopic knee surgery for tears of the medial and lateral meniscus. After months of rehab, I have trouble going up or down stairs, and I have swelling on the lateral side just above the knee. Also, when I bend over to remove weeds from my driveway, I can feel rolling of tendons of tendons or muscles in my calf. I am wondering if I had something other than minor meniscal tears?
