Bursitis occurs when the bursa, a synovial-fluid-filled sac is inflamed. Though slippery and tiny, the bursa has a big job. It acts as a cushion and allows the bones, tendons, ligaments, and muscles to work together without friction. When these tiny water-balloon-like sacs become inflamed and swell, movement is painful.
What causes bursitis?
Many cases of bursitis in the joints result from repeated movement of the joint. It is a type of overuse injury.
But overuse injury is only one cause of bursitis.
Age, arthritis, gout, injury, or surgery are other factors. Being overweight also applies more pressure to the bursa.
The meniscus is a small horseshoe-shaped rubbery pad of fibrocartilage and collagen. These pads inside the knee absorb the impact of motion. Each knee has two of these miniature shock absorbers: the lateral and medial meniscus. Injury to these protective pads results in a meniscus tear.
How do meniscus tears happen?
Athletic training or competition can exert a tremendous force on the menisci. Running, jumping, squatting, or twisting motions can intensify this pressure. During these high-pressure or fast-paced activities, sections of the menisci can tear or move out of place.
But anyone can tear their meniscus. People who dance, play tennis, snowshoe, or ski are […]
You’ve heard that walking 10,000 steps is the best thing you can do for your health. But when you have sore knees, walking five miles may seem impossible.
The good news is that as few as 1,000 steps every day helps maintain mobility in your knees.
According to a study of 1,788 people with an average age of 67 years and a body mass index considered obese, walking just 1,000 steps each day made a difference. The daily exercise lowered the risk of loss of mobility by 16 to 18 percent——even when they were at risk of […]
Runner’s knee is a common overuse injury among runners and other people who put a lot of pressure on their knees when biking, jumping, skiing or dancing.
The condition causes the kneecap (patella) to move out of place. While it is in the misaligned position, it irritates the femoral groove and wears away the cartilage beneath the patella, causing knee pain.
Runner’s knee can be caused by:
Falling on your knee and moving the patella out of the groove
Overuse and repetitive bending and flexing the knee

From the jump ball that starts the game until the final buzzer, basketball sends ten players sprinting and dribbling up and down the court to sink a basket.
All the jumping, running and changing direction can take its toll on players’ bodies.
According to the Centers for Disease Control and Prevention’s National Health Statistics Reports, based on 2011 to 2014 data, basketball injuries topped the list of injuries (343,000) for people between the ages of 15 and 24 and ranked third (264,000) for players who were 25 years old and older.
Basketball’s fast-pace puts players at risk for many types […]
