Hey there Sarah.. I have never heard of this either, so I looked it up on Mayo Clinic.com.. (I love that website) but anyway, this is what it says for treatment:
Treatment of patellofemoral pain often begins with simple measures. Rest your knee as much as possible. Avoid any activities that increase the pain, such as climbing stairs. If needed, take nonsteroidal anti-inflammatory pain relievers, such as aspirin or ibuprofen.
To speed your recovery, your doctor may recommend specific exercises or physical therapy to strengthen the muscles that support your knees, such as your quadriceps, hamstrings and the muscles around your hips. Sometimes physical therapy may include electrical stimulation to strengthen your muscles. In other cases, knee braces or arch supports are recommended.
When you exercise, choose activities that go easy on your knees, such as bicycling and swimming. Your physical therapist may show you how to tape your knee to reduce pain and enhance your ability to exercise.
If these measures aren't effective, surgery may be an option.
- Arthroscopy. During this procedure, the doctor inserts an arthroscope — a pencil-thin device equipped with a camera lens and light — into your knee through a tiny incision. Surgical instruments are passed through the arthroscope to remove fragments of damaged cartilage.
- Realignment. In more severe cases, a surgeon may need to open your knee to realign the angle of the kneecap or relieve pressure on the cartilage.
Here is the website if you'd like.. I don't know if this helps out at all, but I thought it might be worth a shot.. 
Do you have any appt yet with the ortho?
