Tennis and racquet sports leave the foot and ankle susceptible to injury as they are put under considerable stress by the continuous side-to-side motion and quick stopping and starting which the sport requires. Different court surfaces also stress the foot and ankle in different ways.The most common injuries are blackened toenails, ankle sprains, stress fractures, plantar fasciitis, achilles tendonitis and heel pain.
Stress on the bottom of the foot can causes arch pain due to the ligaments of the sole of the foot becoming inflamed and painful. An arch support aids healing in this instance. Stress fractures may usually occur along the metatarsal bones due to the intense pressure and stress. The area becomes swollen causing severe pain when walking. Shin splints are small tears of the calf muscles that attached to the tibia bone along the shin. The muscle may also be torn away from its attachment to the bone causing pain. The condition is treatable with rest, ice, and elevation. These injuries tend to occur on harder court surfaces, and should be healed fully before resuming play. They can be rectified via the use of orthotics or supports.
The development of Achilles Tendonitis may be acute or chronic. A sudden significant increase in activity or the effect of long-term repetitive stress on the tendon may lead to the development of small tears in the tendon which is the most common injury in tennis when landing from a jump. A gel heel cup or a heel lift should be used when not playing tennis in order to alleviate tension on the Achilles.
