What is Osteophytic ridging in lateral and patellofemoral compartments?

Osteophytic ridging in lateral and patellofemoral compartments refers to the presence of bony growths (osteophytes) along the edges of the lateral (outer) compartment and the patellofemoral compartment (where the kneecap meets the thigh bone) of the knee joint. These osteophytes typically develop as a result of wear and tear from osteoarthritis and can contribute to pain, stiffness, and decreased mobility of the knee.
