Knee pain is very commonly seen in sports people and the elderly. More often than not knee pain is a result of either joint surface wear and tear due to repetition/age, cartilage or meniscal damage through sporting injuries or wear and tear or muscle strains in the thigh, hamstring and calf regions.
If the knee does not have time to recover between intensive sessions of exercise/sports/competition then it will slowly become inflamed and irritated. After years of this pattern, ‘wear and tear’ will develop and cartilage or meniscal damage will become more permanent.
If the knee has very sharp pain after a sporting training session/game then the possibility of genuine ligament, cartilage or muscle damage becomes greater. Rapid twisting or changing of directions in football, hockey, netball, basketball, rugby and racket sports may over stress these structures and require treatment.
Arthritic pains, which gradually develop over years often, give rise to symptoms such as morning stiffness, pain walking and pain bending the knees.
Muscle strains often result from overload of the muscles and tendons either from training or spontaneous game/competition situations. These are clear because moving the joint will cause pain in the muscle each time and you will begin to avoid specific movements.
Knee pain can also be referred from the lower back through compression of nerves that exit the spine or through the muscles controlling the hip.
