Document Summary

Taking a history (subjective: mechanism of injury, contact or non-contact. If non-contact, decelerating, cutting, landing: position of foot, planted, odd landing, slipped, sounds (i. e. pop or crack, able to weight bear, continue playing, locking, giving way since, locking = meniscus, giving way = ligament. History: nature of any swelling hemarthrosis, bleeding into the joint, typically occurs more quickly that synovial effusion/capsular swelling, noticeable swelling < 4 hours post-injury, noyes et al. (1980) In adults, 72% were acl tears: patellar dislocation next most common, fractures, meniscal tears, capsular tears may be the cause. In pediatrics, suspect patellar dislocation: past history of trauma, surgeries. Inability to walk 4 steps: high-speed injuries, younger patient who may avulse a bony fragment, clinical suspicion of loose bodies. Subluxed or dislocated patella: patella shifts from its normal position, most often shifts laterally. If patella is dislocated, slightly flex the hip and slowly extend the knee: usually the patella relocates.
