|Chondromalacia of the Knee|
|Copyright © Nucleus Medical Media, Inc.|
- Birth defect in knee alignment
- Weak quadriceps
- Muscle strength imbalance between the inside and outside of the thigh
- Direct trauma
- Participation in activities like running, skiing, cycling, or soccer that put repeated pressure on the patellofemoral joint
- Knock-knee abnormality of the leg
- Acute or chronic knee pain that worsens slowly over time
- A popping or cracking sound as the knee is flexed and extended
- Increased pain when climbing stairs, squatting, kneeling, or running
- Pain and stiffness in the knee after it is flexed for a long period of time
- 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.
- 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
- 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.
