Causes:
RUNNER’S KNEE (CHONDROMALACIA PATELLAE)
Definition:
Irritation of the under-surface of the
kneecap. This smooth cartilage normally
glides effortlessly across the underlying bone during bending and straightening
of the knee. However, in some people the
kneecap sits uneven and tend to rub against one side of the underlying bone,
causing irritation and pain and eventually wear and tear.
Causes:
- Tight lateral knee structures eg. the ITB
- Weak medial quadriceps muscle (VMO)
- Weak hip stabilisers
- Overpronation of the foot (biomechanics)
- Increased angle between the thigh bone and shin bone (Q-angle)
Symptoms:
- Pain when:
- Running, hill walking or going up or down stairs
- Kneeling or squatting
- Sitting for long periods
- Grinding or crunching sound when squatting or going up or down stairs
Treatment options:
- Rest,ice
- Ultrasound, massage,K-tape
- Strengthening of weak muscles
- Stretching of shortened muscles
