Systematic Inspection of the Knee Joint Using the Lateral Approach
- 53 Downloads
The knee is flexed at 90° and is supported by a knee rest. The outer tube of the instrument is positioned transversely in front of the femoral condyle and pushes the intrapatellar fat pad forwards. The afferent and efferent lines are connected to the instrument and the optical system has been inserted into the outer tube. The initial orientation begins during the irrigation of the knee joint. As the Ringer solution flows into the joint the outlines of the femoral condyles become visible. The synovial membrane is progressively displaced by the fluid and the interior of the knee joint becomes visible. This process is repeated in a similar manner during gas filling of the knee joint. Here too, it is advisable to use the inside border of the medial femoral condyle as a landmark and starting point for examination of the knee joint.
