Causes of Runner’s Knee:
- Engaging in activities that require lots of knee bending such as jumping, running etc
- Excessive training (jogging, sprinting etc)
- Injuries
- Worn-out shoes, improper footwear, wrong-sized footwear
- Muscle weakness or muscle imbalance (between the quadriceps and the hamstring)
- Insufficient warming up of the knees before exercising
- Flatfoot
Symptoms for Runner’s Knee:
- Grinding or clicking sound produced when the knee is flexed (bend or straighten)
- Pain around the knee area during or after activity, and persists at rest
- Feeling of weakness or instability of the knees
- Pain during walking, squatting, kneeling, running or even at rest
- Swelling of the affected knee
Treatments (in general):
- Let the knee rest for as long as possible and avoid putting weight on the knee, until the pain has subsided totally
- Ice the knee to reduce swelling and pain
- Provide extra support by using elastic bandages, straps or sleeves and by compressing the knee
- Elevate the knee on a pillow when sitting or lying down to reduce swelling
- Stretch often and engage in strengthening exercises

Preventions:
- Strengthen the thigh muscle and do regular stretching
- Avoid running on hard surfaces such as concrete road
- Adopt a proper running form or technique such as bending your knees when landing or landing on the balls of the feet when jumping
- Wear appropriate footwear and use shoes with good shock absorption to reduce impacts
- Do a proper stretching and warming up before exercising
- Getting arch supports for your shoes may help with flat feet (able to get it from stores or can be custom made)
There isn’t a definite duration for recovery of Runner's Knee. The recovery rate depends to a large extent on each particular case (such as age, extent of injury etc).
