The arthroscopic camera light can assist with finding the correct location. With the leg in a valgus position to put the MCL on stretch, enter the skin at one location with the 18 gauge needle. Do not make multiple skin punctures. Through the one poke hole in the skin, feel for a "gritty" sensation while walking the needle anterior and posterior. The needle tip will periodically contact the bone and pie-crust the MCL in the process to improve medial compartment arthroscopic visualization. This technique has not led to any clinical MCL laxity or medial sided knee pain at final follow-up in our experience. Pie-crusting has many benefits beyond improved visualization. The technique also allows for protecting the medial compartment structures while using instruments and it facilitates performing various procedures as demonstrated in this video.
