Articular cartilage cushions the femur (thighbone) and tibia (shinbone) where they meet in the knee, allowing them to move freely and easily. Chondromalacia patella is a softening or wearing away of the articular cartilage on the undersurface of the patella (kneecap).

Chondromalacia patella is more common in adolescents and young adults. Other factors that increase your risk of chondromalacia patella include:
- Participation in activities like running, skiing, cycling, or soccer that put repeated pressure on the patellofemoral joint
- Knock-knee abnormality of the leg
Talk with your doctor about the best treatment plan for you. Options include:
The knee will need time to heal. RICE is often the main part of treatment:
- Rest—Activities may need to be restricted at first.
- Ice—Ice therapy may help relieve swelling.
- Compression—Compression bandages can provide gentle pressure to help move fluid out of the area.
- Elevation—Keeping the affected area elevated can help fluids drain out or prevent fluids from building up.
Prescription or over-the-counter medications may be advised to reduce pain.
A physical therapist will assess the knee. An exercise program will be created to help recover and to strengthen the muscles in the leg.
In most cases, surgery is not needed. But surgery may be needed if other treatments are not helpful. Surgical procedures include the following:
- Moving the quadriceps muscle insertion on the lower leg to improve alignment
- Releasing the lateral thigh muscles and tightening the medial muscles
- Smoothing over the undersurface of the patella
- Implanting cartilage taken from one’s own knee
To reduce your chances of chondromalacia patella, take these steps:
- Maintain a healthy weight to reduce stress on your knees.
- Properly warm up before exercising or doing any physical activity.
- Maintain proper strength by exercising the quadriceps, calf muscles, and hamstring muscles.
- Use proper footwear for your sport. You may need orthotic support to help correct misalignment.
- Slowly increase activity to avoid stress on the knee.
- Use proper form and technique for any sport.
