No evidence of patellar dislocation or osteoarthritis, meniscal tear or ligament damage. Great relief to hear this, but desperately searching for solutions. I've dialed back my mileage and run flat surfaces only to accommodate the knee pain for months, to no avail. Sought input from a sports medicine doctor who sent me for an MRI suspecting a medial meniscus tear. Clearly a meniscal tear is not the source of my ongoing pain.
