Need help understanding MRI results.
Knee started hurting suddenly on 6/14 during lunge up and over stretch. Rested and all that for a few weeks then finally saw physicians assistant. Had MRI, results were not reviewed I was just referred to physical therapy for 4 weeks 2 x a week.
I feel like the catching is getting worse not better and only get pain when it catches which is usually during excessive walking, getting out of the car after long car ride, and during dance. I am a dance instructor. I teach 3x a week for 2 hours each.
This is my left knee. Here are the MRI findings, any help deciphering what they mean or if PT is really the best method of treatment is much appreciated.

FINDINGS: The anterior and posterior cruciate ligaments and medial
and lateral collateral ligaments are intact. There is a longitudinal
fissure in the anterior cruciate ligament anteriorly which is
probably developmental. No meniscal tears identified. No marrow
edema visualized. There is a fissure in the medial patellar
cartilage. This oblique fissure traverses approximately half the
thickness of the cartilage and results in a small flap. There is no
edema in the patellar retinaculum or lateral femoral condyle bone
bruise to suggest that the patient has had a dislocated patella
recently.
IMPRESSION: Small fissure in the medial patellar facet, otherwise
unremarkable exam.
