FROM OUR EXPERTS
Because bruises are usually the direct result of an injury, the following are important safety recommendations:
Teach children how to be safe.
Be mindful to avoid falls around the house. For example, be careful when climbing on ladders or other objects. Avoid standing or kneeling on counter-tops.
Wear seat belts in motor vehicles.
Wear proper sports equipment to pad those areas most frequently bruised (thigh pads, hip guards, and elbow pads in football and hockey; shin guards and knee pads in soccer and basketball).

Injuries to the anterior cruciate ligament are common among young athletes. Most of these ruptures occur as a result of a noncontact event. Usually, the athlete is landing from a jump with the knee in just the right amount of torque to rupture the ligament. But whether from a noncontact or contact injury, the exact mechanism of injury remains unknown. In this study, researchers used MRIs to identify patterns of bone bruising in athletes with ACL injuries. Studying the impact on bone at the time of injury was helpful. They compared the depth, location, and intensity of bone bruising with the amount of energy generated in the knee at the time of the injury. They found that there was much more bruising in the bone of the noncontact group. The greater amount of bruising in this group points to a larger amount of energy and more damage done with a noncontact injury. Most of the bone bruising associated with ACL ruptures in both groups occurred in the lateral compartment of the knee. The mecha...
Ligament injuries in the knee often have an effect on other parts of the knee. Upon impact, the surfaces of the knee joint may slam into one another, bruising the bones. These bruises are actually tiny fractures of the bone underneath the cartilage. X-rays don't often show the bruises on the bone, but MRI scans can. Researchers in Argentina set out to discover whether a bruised knee bone results in ongoing problems in the knee joint. They did an MRI scan on patients scheduled for surgery to repair a torn anterior cruciate ligament (ACL) in the knee. Participants were included in the study if this was their first knee injury and the MRI showed a bone bruise. Twenty-one people with a total of 29 bruises were found. The bruises were graded based on severity: type I being the mildest and type III being the most severe. Within two to three years after surgery, another MRI was done. Most (91 percent) of the milder bruises disappeared completely. Yet none of the type III bruises went away. Ev...
