In a previous article we discussed chondromalacia patellae. A knee injury, often occuring in teenage girls, sometimes due to sports. Today we’ll go even further and discuss how and why chondromalacia patellae can occur when running.
Sometimes chondromalacia patellae can occur because the upper leg muscles (the M. Quadriceps Femoris) is too weak. That’s why you should do exercises that will make the quadriceps muscle more powerful. Because the M. Quadriceps will get stronger, you should also do exercises for the hamstrings (the antagonist).
Sometimes the Quadriceps and/or hamstrings can be too tight. If that’s the case, you need to make them longer.
The surface where you run can be of importance aswell. The road shouldn’t be higher on the left or right side, as that will make you run like there’s a difference in leg length. Make sure the underground isn’t too hard either!
Too much pronating will cause a lot of stress on the knees. If that’s the case, you are probably wearing the wrong kind of running shoes.
Running uphill or suddenly raising the distance, puts a lot more stress on the knees too.
