ABSTRACT: Methods of preventing and treating knee injuries have changed with the rapid development and refinement of knee braces. Prophylactic knee braces are designed to protect uninjured knees from valgus stresses that could damage the medial collateral ligaments. However, no conclusive evidence supports their effectiveness, and they are not recommended for regular use. Functional knee braces are intended to stabilize knees during rotational and anteroposterior forces. They offer a useful adjunct to the treatment and rehabilitation of ligamentous knee injuries. Patellofemoral knee braces have been used to treat anterior knee disorders and offer moderate subjective improvement without significant disadvantages. Additional well-designed studies are needed to demonstrate objectively the benefits of all knee braces. Knee braces should be used in conjunction with a rehabilitation program that incorporates strength training, flexibility, activity modification and technique refinement.
ABSTRACT: Although historical findings have some value in diagnosing internal derangement of the knee, a thorough physical examination can often rule out fracture and ligamentous and meniscal injuries. The Ottawa Knee Rule can help physicians determine which patients require radiography. Positive physical examination tests and findings of acute effusion suggest internal derangement. An abnormal McMurray or Thessaly test strongly suggests meniscal injury, whereas a normal Thessaly test may rule out meniscal injury. Absence of evidence of joint effusion significantly decreases the probability of internal derangement. Magnetic resonance imaging should be reserved for ruling out internal derangement in patients with suggestive historical and physical examination findings.
