Draining a large knee effusion. You can enter knee medically, laterally, and either side of suprapatellar area. Note nearly horizontal angle of needle which may reduce a traumatic tap after much fluid is removed.

How to demonstrate tenosynovitis- milk it to increase pressure and show a fluid wave. Rheumatoid arthritis often has extensor carpi ulnaris involvement and is often associated with an ulnar styloid erosion.

When injecting a knee while pt is sitting, the infrapatellar fat pads are the hint of where to go either medically or laterally. Helps with landmarking.

Injection. Easy. Find point of maximal tenderness on palpating and should localize to that area with resisted extension of the wrist.
