America's favorite contact sport, football, incidentally has the highest level for associated injury. According to statistical studies conducted by the American Journal of Sports Medicine, the most prevalent of all injuries suffered by football players are knee injuries, followed by injuries to the ankle. Injury to the medial collateral ligament of the knee is the most common among these knee injuries. Meniscal perforations are next, followed by injuries to the ACL. Incidence of American foot ball injuries studies indicate, ACL injuries required surgery twice as many times as patellar or meniscal tears, 63% and 36% respectively.   Unfortunately, the typical therapeutic treatments utilized for knee pains in professional sports rely largely upon pharmacological interventions which further exacerbate the knee problem. Additional injury from running with knee pain is frequently unmitigated due to the use of painkillers and steroids. These drugs, although initially a welcome relief for knee pain, deceptively mask the usual signs indicative of compounding injury to the knee permanently damaging the ligaments of knees beyond repair.   Both visual and tactile recognition for knee injuries are realized through the consistent wearing of a knee brace. The continual pressure upon football players like Tim Tebow to suffer through the game and an athlete's inherently high pain tolerance are two primary reasons to employ knee braces for injury prevention.   Forceful muscle contractions surrounding the musculotendinous junction result in a muscle injury referred to as a strain. Research confirming strain injury mechanics shows increased energy absorption by stronger muscles, thus less prone to injury than muscles which are fatigued. Fatigue, improper warm-up prior to activity and previous injury are strongly associated with acute muscle strain injuries in clinical experience. A knee brace stabilizes the ligament during subsequent weight-bearing knee exercises gradually strengthening knee ligaments in rehabilitation. Providing stabilization and adjustable levels in limitations upon motion, a knee brace prevents hyperextension frequently associated with prior knee injuries.   If you're a football player, taking preventive measures against knee injuries could not only save you unnecessary pain, but knee braces can also increase your longevity in the sport itself.
