He denies having any difficulties with his left knee prior to the injury of June 13, 2002.,DIAGNOSTIC STUDIES: , August 2, 2002, MRI of the left knee showed low-grade chondromalacia of the left patellofemoral joint space and a posterior horn tear of the medial meniscus, likely degenerative in nature, and also grade II to III chondromalacia of the medial joint space.

He brought with him copies of x-rays taken July 16, 2007, of his left knee, which I reviewed and which showed marked narrowing of the medial compartment of his left knee with spurs on the margins of the joint medially and also spurs on the patella.  There was subluxation of the tibia on the femur with standing.,After his injury, he received treatment from Dr. X for patellofemoral syndrome with knee sleeve.
