It’s certainly common sense to surmise that amateur athletes are more susceptible to knee injury than the anyone else. Even professional athletes are not immune. Professional tennis player Lindsay Davenport had to withdraw from the Olympic singles competition because of a knee injury.
Golf superstar Tiger Woods recently returned to the PGA Tour after several months of rehabilitation from knee surgery. NFL quarterback Tom Brady missed nearly an entire season for the same reason, a knee injury.
Although they’re all nearly back to full strength, they haven’t seen the last of knee problems. An established fact is that injuries such as these increase the risk of developing knee osteoarthritis.
Osteoarthritis, or “wear-and-tear” arthritis, is caused when the cartilage that protects your bones wears away. This can become extremely painful when it occurs in the knees. You don't have to be an athlete to develop osteoarthritis, but the injuries suffered in sports have been found to increase the risk of this happening. A study conducted by the Department of Neuroscience and Locomotion in Linkoping, Sweden shows that individuals with previous knee injuries possess a higher risk of developing osteoarthritis of the knees.
For this population-based case-control study, they investigated, with respect to sports activity and previous knee injuries, the risk of knee osteoarthritis. In the study, 825 cases with x-ray verified osteoarthritis, were matched (age, sex, and residential area) with 825 controls from the general population. Mailed questionnaires, asking for sports activity after the age of sixteen, knee injuries, and other variables were collected and analyzed using logistic regression models. It was concluded that knee injuries were the factor for increased risk of osteoarthritis.
Aside from the effects of the previous or existing knee injury, osteoarthritis symptoms include:
. Stiffness (especially morning knee stiffness)
. Knee pain that gets worse when running or climbing stairs
. Limitations in range-of-motion
. A “crunching” feeling in the knee when active
. Inflammation, and fluid build-up, in advanced cases
All of these symptoms will greatly impact athletic performance while playing sports.
Sadly, knee injuries can't always be prevented. However, certain precautions, if taken, can put the odds back the athletes’ favor. Performing any or all of the following suggestions will help with this as well as with athletic performance:
. Get the right equipment. There are lots of shoes designed specifically for the sport, not running shoes, with good cushioning and inner and outer side support.
. Use good technique while playing to reduce the risk of turning or twisting the wrong way or angle.
. Stretching is a great way to warm-up the muscles and joints. Work some active, or dynamic stretching into your routine like jogging around the court and doing side shuffles. This will help prepare your body for the physical strain of playing.

No one can control everything that happens during competion. Armed with this information though, players can take steps to reduce the likelihood of developing osteoarthritis of the knee, thus making it possible to remain competitive well into the later years.
If you suspect that you have knee osteoarthritis, it is critical to seek the urgent consultation of a local sports injuries doctor for appropriate care. To locate a top doctor or physical therapist in your area, please visit our Find a Sports Medicine Doctor or Physical Therapist Near You section.
