Dull, aching pain around the front of the kneecap (the patella) where it connects to the lower end of the thighbone (the femur). Causes of Runner’s Knee include the kneecap being out of alignment, overuse, previous injury or weak thigh muscles.
The term “shinsplints” refers to the pain that develops along the inside of your shin (the tibia bone). It’s also known as medial tibial stress syndrome (MTSS). Shinsplints commonly affects runners, aerobic dancers, and people in military boot camp. It’s caused by repeated movements during exercise cause muscle fatigue.
You may be more likely to develop MTSS if you have flatfeet or abnormally rigid arches, have “knock-knees” or “bowlegs”, are a frequent runner or an aerobic dancer.
