Patellar tendinitis and patellofemoral syndrome (PFPS) share a common cause: decreased quadriceps function and lateral patellar deviation. Chondromalacia is a condition where the cartilage on the posterior surface of the patella wears down; when combined with patellar tendon lesions, it exacerbates pain when going up and down stairs. It is possible to treat both conditions simultaneously conservatively without arthroscopic surgery, and strengthening exercises for the vastus medialis (VMO) are the core rehabilitation program. In Korean medicine, cartilage is related to the function of the body's fundamental energy governing bones, while tendons are related to the function governing muscles. If patellar tendinitis and cartilage damage occur together, it is highly likely that the underlying cause is a weakening of both of these functions. At Dongjedang, we establish a treatment plan that encompasses both conditions; locally, we facilitate the circulation of Qi and blood around tendons and cartilage using acupuncture, moxibustion, and pharmacopuncture, while systemically, we restore the entire muscle and bone structure using constitution-tailored herbal medicine that simultaneously nourishes both fundamental functions.
