20 Assessment of the Knee Fluid in the Knee Bulge sign: medial aspect knee, displace fluid upward, tap lateral patellar margin and note fluid returnBallottment:force fluid into joint space; displace patella
21 Ballottment:force fluid into joint space; displace patella
23 Knee Support and Stability Anterior and posterior cruciate ligaments connect the inner surfaces of the head of the femur with the head of the tibia. They cross each other, anterior ligament extend from the inside of the lateral condyle of the femur to the medial side of the tibial head, and posterior ligament extend from the inside of the medial condyle of the femur to the lateral side of the tibial head.
26 Diagnostic Tests Arthrocenthesis Arthrography Aspiration synovial fluid; reduce pain; dx; treatmentAnalysis joint fluid: usual clear, high viscosity, scant fluidTeaching: no restrictions; consent form; slight painPost-op: RICEArthrographyRadiographic exam, use air or contrast medium:; 90-95% accuracyTeachingComplications: infection, allergyPost-op: Rest joint 6-12 hrs, use ice
27 Arthroscopy Therapeutic /diagnostic Visual recording; surgical removal of meniscus, foreign bodies, etcRare complications; depends on procedure, operative length, use of tourniquetTeachingPost-op care
