Doctor's Notes on Chondromalacia Patella Symptoms, Treatment, Surgery, and Cure
Chondromalacia patella (patellofemoral syndrome) is the weakening and softening of the cartilage on the underside of the kneecap (patella) and is a common cause of knee pain, especially in women. Degeneration of this particular cartilage occurs because of improper alignment of the kneecap as it slides over the bone of the thigh (femur).
Symptoms of chondromalacia patella may include a vague discomfort of the inner knee area, that is aggravated by activity (for example, running, jumping, climbing, or descending stairs) or by prolonged sitting with the knees in a moderately bent position; a vague sense of tightness or fullness in the knee area, particularly if the knee is swollen; and if chronic symptoms are ignored, the associated loss of quadriceps (thigh) muscle strength and bulk may occasionally result in leg weakness.

Aerobic ExerciseAerobic exercise is moderate physical activity that's sustained for a few minutes with the goal of improving health. Walking, biking, swimming, dancing, and jogging are examples of aerobic exercise. Aerobic exercise has many benefits, including improving bone density, endurance, HDL, weight control, insulin resistance, balance, and odds of surviving a heart attack and reducing blood pressure, cancer risk, body fat, and triglycerides.
ExerciseExercise has been shown to reduce one's risk of heart disease, diabetes, colon and breast cancer, lower blood pressure and cholesterol, and reduce depression and anxiety. The Surgeon General recommends accumulating 30 minutes of exercise on a daily basis.
Joint PainJoint pain can be caused by injury or disease affecting any of the ligaments, bursae, or tendons surrounding the joint. Pain also occurs with joint inflammation (arthritis) and infection. Joint pain symptoms can be associated with local warmth, swelling, and tenderness. Treatment depends on the cause and can include rest, cold applications, medications, physical therapy, or surgery.
Knee InjuryKnee injuries may be caused by a direct blow to the knee or by twisting or stretching of the ligaments, tendons, and surrounding muscles. Knee pain and swelling are common symptoms and signs of a knee injury. Treatment depends upon the type of knee injury but usually incorporates rest, ice, compression, and elevation. Strengthening exercises and physical therapy may also be necessary.
Knee PainKnee pain has a wide variety of causes and treatments. Home care for knee pain includes protecting the knee from further trauma, in addition to resting, icing, compressing, and elevating the knee. In order to diagnose knee pain, the doctor may need to perform a physical exam; get a diagnosis with an X-ray, CT scan, or MRI; remove fluid; perform blood tests; or perform an arthroscopy. Treatment of knee pain depends upon the cause of the knee pain.
Magnetic Resonance Imaging (MRI)Magnetic resonance imaging (MRI) is a scanner that takes cross-sectional images of the body. It is used to evaluate tissues of the head, neck, chest, limbs, abdomen, and pelvis. MRI is a very safe procedure; sedation may be used for infants, small children, or adults who are claustrophobic.

X-RaysX-Rays are a form of radiation used to image solid forms inside the body. X-rays are administered by radiologists for many different routine tests, such as mammograms, checking for broken bones, upper GI series, and dental exams, among others. Radiologists carefully monitor the X-ray equipment to make sure the patient receives the smallest dose of radiation possible.
